6a. Origin of the proposal
Beta-decay studies of exotic nuclei are one of the main goals of the DEcay SPECtroscopy
(DESPEC) setup to be installed at the Low Energy Branch (LEB) after the Super FRagment
Separator (Super-FRS) of the FAIR facility. The intense beams of exotic nuclei that will become
available at the Super-FRagment Separator (Super-FRS) of the FAIR facility will give the
opportunity to study the nuclear structure and dynamics of extremely neutron rich nuclei. The
different exotic beams will be separated using (Super-FRS) and finally stopped in the
implantation detectors for the measurement of their β-decay properties with the help of
different devices being devolved under the DESPEC collaboration.
The knowledge of the β-decay strength function Sβ(E) and the properties of nuclei lying far from
the stability contributes decisively to our understanding of nuclear phenomena in the nuclear
structure, astrophysics and nuclear technology fields. Special interest has evoked on the study of
exotic nuclei in the neutron rich side where the nucleo-synthesis r-process take place or the
evolution of the shell structure is unknown as it approaches the neutron drip line. The accurate
measurement of the half-lives, magnetic moments, masses, distribution of decay probabilities
and particle emission probabilities provides essential data for the determination of the full βstrength distribution in exotic nuclei.
All of the experiments anticipated within the DESPEC collaboration involve implantation prior to
the decay. In most cases this will involve active DSSD systems. There is a need for such a system
to correlate implanted ions and subsequent generations of charged particle (β, p, α) decays
where high rates can be expected. In general such a system will also require high resolution,
both for signal to noise discrimination and because the physics (e.g. 2p decay studies) demands
such precision for comparison with theory.
The decay of very neutron-rich nuclei is, however, owing to the high Qβ and relatively low
binding energies of the daughter nuclei, often associated with delayed neutron emission from
the population of unbound states in the daughter nuclei. As a result β-delayed neutron (βdn)
emission becomes the dominant decay mode at the neutron drip line. The decay probability,
energy and branching ratios of βdn are essential to map the β-strength function Sβ(E) of nuclei
far from stability. Moreover, the delayed neutron emission of neutron rich nuclei plays an
important role in the nucleo-synthesis r-process as well as in the kinetic control of advance
reactors (e.g. decay heat calculation).
Beta delayed neutron emission is important in terms of nuclear technology, since it is one of the
key features for the safe operation of actual nuclear power plants. Moreover a detailed design,
safety assessment and operation of more advanced reactor concepts such as Accelerator Driven
Systems (ADS) or Fast Reactors, proposed for the transmutation of Nuclear Waste, will certainly
benefit from improved nuclear databases. Delayed neutron data obtained at FAIR will allow us
to complete the international nuclear data libraries and serve as input to more accurate delayed
neutron summation calculations and more detailed Monte Carlo simulations.
Fig. 1. The beta delayed neutron and gamma ray emission process.
The beta-delayed neutron emission leaves the final daughter nucleus not only in its ground state
but also in excited states (as shown in Fig. 1), which immediately de-excite via gamma ray
emission. Indeed, valuable and complementary information on the nuclear structure of both the
final and the emitter nuclei is obtained with the combined detection of the neutron and gamma
rays. Thus, the goal of an ideal beta delayed neutron experiment is to measure individual
neutrons with high efficiency, good energy resolution and in coincidence with the gamma rays
measured with a high resolution gamma-ray set-up. Such an experiment would allow the
reconstruction of the complete energy released in the decay chain. However, experimental
difficulties arrive when trying to detect neutron and measure its energy with high efficiency and
low energy threshold.
Therefore, in order to map the full decay strength, a system for detecting neutrons with
energies up to some 20 MeV with good efficiency and high energy resolution is required. In
order to determine the neutron emission probability and energy, a time-of-flight spectrometer
based on scintillation detectors have been proposed for the DESPEC project. This report is
devoted to the design and technical description of a Time Of Flight (TOF) MOdular Neutron
SpectromeTER (MONSTER) for performing neutron spectroscopy at DESPEC at FAIR. High energy
resolution, high efficiency as well as n-γ discrimination and cross-talk rejection capabilities are
the main requirements for such a spectrometer.
Another important area we like to address is the isospin dependence of nuclear level density
(NLD). NLD is one of the important ingredients of all statistical model calculation. The excitation
energy and angular momentum dependence of nuclear level density is explored to an extent;
however very little is known to the isospin dependence of NLD. The set-up proposed for DESPEC
will give suitable opportunity to study NLD by detecting the evaporated neutrons of neutron rich
nuclei in-coincidence with daughter nuclei in the DSSD
6b. Definition of the problem:
A schematic view of detectors required for the decay spectroscopic studies are shown in Fig. 2.
The neutron detector array forms the outer part of the focal plane detector system of the
DESPEC facility. At DESPEC the beams will be stopped at the implantation device, typically a
silicon strip detectors. Each implanted ion will be identified using the information gained from
the Super-FRS ancillary detectors and the implantation setup. The β-decay spectroscopy will be
performed by measuring the β-delayed radiation (mainly γ-rays and neutrons) correlated to the
β-particles detected at the implantation setup. Since the study of the r-process nuclei is one of
the highest scientific priority of the DESPEC, the development of a modern high efficiency
neutron detector array is necessary for the measurement of β-delayed one- or multi-neutron
branches. Another important aspect is the detection of β−n−γ coincidences to identify the levels
in the A-1 (-2,-3) nuclei which is inaccessible by the β−γ spectroscopy alone.
Fig. 2: Schematic top-view of the experimental set-up for “complete” spectroscopy with
stopped beams. This set-up will be situated in the Low Energy Cave.
Even at FAIR, the production cross sections of very neutron rich nuclei will be relatively low
compared to those of stable nuclei. For these reasons, efficient and selective techniques are
essential in the determination of decay properties of β-delayed neutron emitters. High
efficiency Double Sided Silicon Strip Detectors (DSSSD) and germanium detectors have been
proposed for the β and γ-ray detection. The MOdular Neutron SpectromeTER described in this
report is proposed for performing the β-delayed neutron spectroscopy.
For measurement of neutrons in the environment of γ and β fields, liquid scintillator
based neutron detectors are the best candidates because they have good pulse shape
discrimination property. Among liquid scintillators, BC 501A (EJ301) has excellent pulse
shape discrimination property.
Proposed neutron TOF Array: MONSTER (MOdular Neutron SpectromeTER):
A neutron detector array MONSTER (MOdular Neutron SpectromeTER) has been proposed for
the measurement of the beta decay properties of neutron rich isotopes at the DESPEC (decay
spectroscopy) experiment. The spectrometer will be sensitive to β-delayed neutron with
energies ranging from 100 keV to 20MeV and allow reconstructing its energy by time of flight.
MONSTER will consist of ~ 200 numbers of BC501A liquid scintillator based neutron detectors. It
has been decided that VECC along with other Indian collaborators (BARC and Panjab University)
will make 50 such cells for MONSTER array in collaboration with CIEMAT – Madrid. The
performance of the individual cell will be characterised at both the laboratories, with neutron
and γ - ray sources, and with reference monochromatic neutron beam at the neutron metrology
facility of the PTB-Braunschweig. The final array will be installed at the LEB, in conjunction with
other detectors for DESPEC.
The experimental set-up and technical specifications:
The neutron energies will be determined by a standard time-of-flight technique whereby the
“start” is provided by the β–detector (silicon or plastic scintillation detector) and the “stop” by
the neutron detector module(s). The spectrometer will require some ancillary detectors (Fig. 2):
silicon or plastic scintillation detectors for the β-particles and an array of Ge detectors for
detecting γ’s. These should be placed close to the source and the amount of dead material
should be minimised, imposing restrictions on the construction of the beam pipe. The digital
data acquisition system will be used, and the pulse shape analysis of the BC501A light output
will provide discrimination of n- γ event.
Coincident β-n and β-γ-n events will be recorded in order to determine the delayed neutron
emission probabilities, energies and decay schemes. The energy of the delayed neutrons will be
derived from the time difference between β-trigger and a signal in the neutron spectrometer.
The γ-ray background in the neutron detectors will be rejected by time-of-flight (for prompt
coincident gammas) and by the pulse-shape analysis.
The overall strategy that is being adopted in designing this array is the following:
•
•
•
•
High detection efficiency, which allows detecting neutrons emitted by exotic nuclei produced at
very low yields.
High energy resolution, in order to reveal fine structure of neutron emission in nuclei with high
level density.
Low energy detection threshold, which allows for improved detection efficiency at the energy
range of β-delayed neutrons, from tens of keV up to 20MeV.
Neutron-gamma discrimination capability, because of neutron emission competes with gamma
de-excitation
•
•
Modularity, in order to distinguish between single and multiple neutron emission events (β-n, β2n, β-3n,…), by applying cross-talk rejection
Low sensitivity to gamma radiation and background events
6c. Objective and connection to the main FAIR experiment:
The main objective is to study the structure of unstable nuclei using decay spectroscopy. The
Facility for Antiproton and Ion Research (FAIR) at Darmstad will offer completely new possibilities
for the exploration of phases and structures created by the strong interaction. The Nuclear
Structure, Astrophysics and Reactions (NUSTAR) collaboration has been formed to investigate the
full scope of the nuclear many-body problem.
The Super FRagment Separator (Super-FRS) is one of the major facilities in FAIR. The intense
beams of exotic nuclei that will become available at the Super-FRS of the FAIR facility will give the
opportunity to study the nuclear structure and dynamics of extremely neutron rich nuclei. One
of the major activity at low energy branch of Super- FRS is DESPEC project under NUSTAR
collaboration, which will allow to study the structure of exotic nuclei through their decay.
Decay studies lie at the very frontier of the field of exotic nuclei, since once the existence of an
isotope has been demonstrated, the next elementary information we seek is how it decays.
Experiments can be performed with very high sensitivity and key physical information can be
gleaned from a relatively small number of events. The Super FRS system will allow the fast (
<=100ns), efficient transportation of short-lived exotic nuclei, with clean in-flight particle
identification.
The accurate determination of the beta decay strength function Sβ(E) for nuclei lying far from
stability is important for many facts of nuclear structure physics, nuclear astrophysics. For
example, β-decay by neutron-rich nuclei plays a key role in the astrophysical r-process, during
which heavy elements are built up by successive neutron capture and β-decay. At FAIR studies of
very neutron-rich exotic nuclei lying along whole new swathes of the r-process path will be
possible. The key physical information sought from these nuclei are the β -decay half-life, β delayed neutron branching ratios, and neutron separation energies. Decay studies using the highly
efficient Super-FRS with implantation detector systems will be able to address the first two issues.
Such studies will also be vital to provide valuable information on the development of nuclear
structure between β - stability and the r-process path, as well as the first insights into the
evolution of shell structure towards the neutron drip line.
6d. Deliverables:
Modular neutron spectrometer will consist of 200 neutron detector cells containing liquid
scintillator. Cylindrical cell will be of 8 inch in diameter and 2 inch in thickness. The cylindrical cells
will be coupled with light guide followed by a 5 inch photomultiplier tube (Hamamatsu R4144).
Each detector will be coupled with a digitizer, indigenously developed within the collaboration.
Neutron energy will be measured using time of flight method, using start from silicon detector and
individual stop using neutron detector. We will make 50 such neutron detector cells along with
the respective electronics details of which are discussed in sec. 9.
6e. List of components to be developed in India:
Under the Indian collaboration we are planning to design, develop and fabricate 50 number of
MONSTER module. Moreover, we will also participate in the development of DAQ for the digitizer.
7. Importance of the project in the context of Indian activities (both technical and physics):
We have a strong synergy as far as neutron detector development is concerned. The detectors for
the MONSTER array will have slightly different design and dimensions with reference to detector
developed in VECC.
The readout electronics and data acquisition of the MONSTER detectors will be based on digital
electronics. Participation in the present project will give opportunity to learn more about the
present day’s state of the art of digital electronics.
The proposed neutron array, MONSTER (MOdular Neutron SpectromeTER), will be used for the
measurement of the beta decay properties of neutron rich isotopes at the DESPEC (decay
spectroscopy) experiment. Participation in Decay spectroscopy experiment will give the
opportunity to study the properties of exotic nuclei in the neutron rich side where the nucleosynthesis r-process take place or the evolution of the shell structure is unknown as it approaches
the neutron drip line.
8. Review of the expertise available with proposed group/Institution in the subject of the project:
VECC has almost decade long experience in the development of different types of neutron
detectors viz. (i) 4π neutron multiplicity detector and (ii) time of flight (TOF) neutron detector
array. The 4π Neutron multiplicity detector developed under SUCCUP (super conducting cyclotron
utilization project ) phase I allows to measure, event by event, with high efficiency, the number of
neutrons emitted in a nuclear reaction. These observables provide information about the energy
deposited in a nuclear reaction and collisional impact parameter. On the other hand, TOF neutron
detector array, which will be developed under SUCCUP phase II, is capable of measuring neutron
energy and angular distribution, which will be useful for the study of nuclear reaction mechanism
in general, and study of dissipative nuclear dynamics, in particular.
Under the TOF neutron detector array development programme, an array of 50 detectors is
being set up, which may be augmented in future. The detectors are liquid scintillator (BC501A)
based, having excellent n-γ discrimination property and time resolution. Prototype detectors of
different sizes have been fabricated in SUCCUP phase I and their properties have been studied for
finalizing the detector geometry. On the basis of these studies, it was decided that a combination
of 5" and 7" detectors will be used for the TOF array at VECC. The detectors are being built at
VECC.
The similar modular neutron detectors will be required for the proposed setup at FAIR. Thus, we
have the expertise and the know-how to build neutron detector array necessary for the
proposed physics goal at the FAIR. The experience gained at VECC will be used to develop the
neutron detectors for MONSTER array for DESPEC project under the NUSTAR collaboration.
Moreover our other collaborators from BARC and Punjab University are also involved with
similar project in their respective institutions.
Methodology:
9a. Methodology of the implementation of the full project:
Preliminary R&D on the different types of neutron detectors have already been done
extensively. Details summary of which is already reported in the TDR. On the basis of these
studies, the design of the neutron detector cells have been finalized. The MONSTER
spectrometer will consist ~ 200 of detector cells, and India will provide 50 such detector cells. It
is expected to be execute this development in several phases in several years. The first phase
consisted of a batch of 30 individual modules for the demonstrator version of the spectrometer.
The second phase will consist of 20 detector modules and the third phase will consist of 50
modules. Finally a last phase will include the development of rest of the detector modules.
9b. Plan of R&D:
Ciemat- Madrid, have done extensive R&D on different properties of scintillators (as described
in TDR), electronics and the mechanical support structures and on the basis of these studies, the
design of the detector cell , electronics and mechanical support structures have been finalized.
The technical design and specifications of the MONSTER Spectrometer for DESPEC is presented
here :

Under the proposed project, few proto-type detectors will be first developed and tested.
Performance test will be done on pulse height resolution, pulse shape discrimination, efficiency
measurements, pulse height response for mono energetic neutrons.
Prototype detector development at VECC, India.
The Indian collaborators developed first proto-type MONSTER cell. The actual photograph of the
MONSTER cell is shown in Fig. 4. The cell was initially coupled with Photonics PMT XP4512B and
tested. It will be replace by the Hamamatsu PMT R4144 (decided by the collaboration), which is
already ordered.
Figure 4. Proto-type MONSTER cell developed at VECC.
The proto-type cell was tested with analogue electronics. The pulse shape discrimination property
was measured with 241Am-9Be neutron source.
Figure 5. Pulse shape discrimination spectra.
The pulse shape discrimination property has been tested with zero cross- over technique. The
pulse shape discrimination spectrum was extracted at a threshold of 150keVee, shown in Fig.5.
Fig. 6 shows the figure of merit vs. pulse height threshold applied. Figure of merit initially
increases and then it saturates at a threshold of 150 keVee. The intrinsic time resolution of the
detector has been measured using a 60Co source with a 1" thick BaF2 detector. The intrinsic time
resolution is shown in Fig. 7. The intrinsic time resolution of the MONSTER cell was found to be
700 psec. The more detailed testing, such as efficiency measurement and pulse height resolution
are being done.
Figure 6. Figure of merit vs. pulse height threshod.
Figure 7. Intrinsic time resolution.
ii) Electronics:
Readout electronic and data acquisition will be based on digital electronics. R&D efforts have
already been started at CIEMAT Spain, to develop low cost digital electronics for both charge
(QDC) and time (TDC) measurements. Very good performances have already been demonstrated
for single - channel cards, and it is envisaged that within 3 years very low-cost multi channel
capabilities will be available for a 200 scale detector array.
The main parameters, energy deposited and time will be obtained by processing the digitized
signals by using appropriate algorithms. Charge integration, pulse shape discrimination and
timing algorithms have already been tested with signals digitized with commercial flash-ADC
boards. Specific logic condition on the individual signals like amplitude or charge over a
threshold will be used to provide the trigger for the acquisition and allows establishing time
correlations with implantation detector and other detectors. However a trigger solution based
on analogue fast electronics is also considered for specific measurements.
Front-end electronics
The readout electronics scheme proposed for MONSTER is shown in Fig. 8, is based on digital
electronics and standard commercial fast electronic modules. Anode signals will be digitized at
1GSample/s sampling rate and 12 bits resolution. The main parameters, energy deposited and
time will be obtained by processing of the digitized signals by using appropriate algorithms.
The digitizer board is under development having an energy branch derived from the PMT
dynode signals and a timing branch derived from the PMT anode signals, and R&D is being done
to improve its performance. In both cases the signals are processed individually and hardware
summed.
Figure 8. General electronics scheme. TFA: Timing Filter Amplifier, CFD: Constant Fraction Discriminator,
GDG: Gate and Delay Generator.
The timing information will be used to provide the trigger for the acquisition and allows
establishing time correlations with implantation detector and other detectors. In order to allow
for a minimum threshold trigger the timing signal must be derived from the analogue sum of all
detector module signals. On the other hand the best timing performance for the correlations is
obtained from the individual modules.
High voltage supply and gain stabilization system
Of particular importance for the performance of the spectrometer and the accuracy of the
results is the stabilization and matching of the gain of the different photomultiplier tubes. The
accuracy of the reconstruction of energy spectrum requires a good matching between the
energy spectra of the individual modules. It is required to keep gain variations of the PMT below
0.5 % in order to avoid noticeable distortions of the spectrum. Gain variations will be monitored
using a stable reference light signal. The remotely controllable Power Supply System like
SYS2527 from CAEN equipped with A1733 and A1535D HV cards will be used.
Data acquisition system
A data acquisition system is under development for digitizers to be used with MONSTER. It is a
version of the Data Acquisition for Integral SYstems (DAISY) of the Unidad de Innovación Nuclear
of CIEMAT. The software has been developed with the QT- application framework and the main
features of its design are the modularity and scalability.
iii) Mechanical support and shielding
The mechanical support structure for the spectrometer has been designed under the following
criteria: low mass, mechanical stability and robustness, versatile for different flight paths and
reproducibility of single detector position, scalable and easy assembling. It will be made of a
high purity aluminium alloy in order to reduce the background due to neutron induced reactions
in the structure.
Our Plan:
Initially, at VECC , 4nos. of such detectors will be developed. After successful performance of
these detectors (to be tested at VECC and PRESPEC Campaign), India in total will fabricate 50
such detectors for the array. Another 30 detectors are ready by CIEMAT Spain. India will also
participate in testing and in beam experiments to be performed by CIEMAT using array of 30
detectors. We will also participate in the testing of the digitiser and the development of the
DAQ. After completion and installation of whole array, we will participate in different DESPEC
experiments to be performed at DESPEC setup at LEB of Super -FRS.
In- beam performance test:
After the characterisation of the individual cells at the laboratory, the detector will be first used
at the IGISOL facility at the University of Jyvaskyla (JYFL), for the measurement of the β-decay of
87,88
Br, 94,95Rb and 137I. Fig. 9 shows schematic of the experimental configuration that will be
used at JYFL.
Fig. 9. Schematic view of the setup proposed at JYFL.
In the PRESPEC campaign and in other proto-type test the following points will be investigated.
-
-
-
Performance of the detectors in real conditions: degradation of the time resolution,
electronic noise with and without beam, blinding of the detectors due to Bresstrahlung
radiation and other possible effects.
Determine the sources of background. The magnitude, time correlation, multiplicity and
energy distribution of the sources of background which limit the technique, will be
measured.
Determination of the energy resolution and the energy threshold of the MONSTER in the
combination with the implantation set-up. The energy resolution depends directly on the
time resolution and energy threshold of the implantation set-up (start signal) and the
neutron detectors (stop signal). It will be preferred to use the AIDA DSSSD array if available
at the time of the test beam. Implantation detector such as the RISING DSSSDs could be
used alternatively.
9c. Production Plan (if R &D is successful): After the successful proto-type testing with both
conventional analogue electronic s as well with commercial digitizer, detector fabrication will be
started in batches and 50 numbers of detectors will be indigenously developed in two/ three
batches. The charecterisation of these detectors will be done at VECC, PU and BARC.
9d. Time schedule of the R&D and Production:
We are expecting to finish our R&D during 2014 -2015 and will be able to start our production
2016 depending upon the monitory sanction of the project.
