Recommendation (iii)
The UNILAC upgrade will provide one order of magnitude greater
beam intensities than today. This is a major improvement which
will greatly enhance the program to search and study super heavy
elements.
The realisation of this up-grade is considered highly important and
the committee lends it its full support.
LINAG, the SPIRAL2 driver is another attractive possibility
as it fully matches the specification of the needed high intensity
stable ion beam facility,
a significant amount of beam time is foreseen to be used for the
production of high intensity light and medium mass stable ion beams
This project is recommended as a first step to the desired facility as
well as its future upgrade to heavier masses (LINAG2)
It is an important proof of feasibility and test bunch for all technical
issues related to very high intensity heavy ion beams.
Recommendation (iv)
It is clear that the use of the upgraded UNILAC and the very intense light and
medium beams from LINAG is an attractive short-medium range perspective
for the community from the point of view of the physics opportunities
and also from the point of view of the possibilities of testing and
improving instruments and methods.
The long term goal for a new dedicated high intensity stable ions facility
in Europe is considered to be one of the important issues to be discussed
and considered in the next Long Range Plan of the nuclear physics
community. In this context, the importance of an complementary
low-energy-high-intensity stable-beam facility dedicated to
Nuclear astrophysics studies needs also to be considered.
Recommendation (v)
In order to be ready for this new project it is also highly important that
research and development on the various related keys issues such
as target, spectrometers and ion sources, are initiated and organised
at the European in synergy with future RNB projects:
1. Development of High current ion sources
2. Development of high power thin targets
3. Improvement of the ion-optical properties of the separator
with respect to high transmission and reduced background.
3. Increase of the detector granularity and installation of an
appropriate signal processing and data acquisition system.
ECOS
‘ Network within ENSAR’
The objectives of ECOS:
--Bring together and coordinate the expertise that is available in the European
countries in order to achieve the research and developments activities needed
in all aspects related to the production and use of high intensity heavy ion
beams.
--Optimize resources and manpower for the up-grade and development of
various stable ions beam facilities in Europe in order to
optimize their scientific output. From this point of view, NA02-ECOS has a
direct link to the TNA delivering stable ion beams to the users community in
Europe. These are GSI, GANIL, LNL/LNS, JYFL , ALTO and KVI
Description of work
Task 1 High power thin-target technology
The maximum usable primary beam current with thin targets is among others determined by the long-term stability of the thin
targets under irradiation. High beam intensities lead to a considerable heating of the targets, and, hence to thermal stress, possibly
phase transitions, oxidation or reduction of the chemical compounds and diffusion into the target backing respectively.
We propose to study these phenomena in detail and to compare for example the performance of thin actinide targets as function of
the production method (painting, spray-painting, electrolysis, electro-deposition, evaporation and sputtering), the used chemical
compounds (oxide, carbide, others) and backings/coatings respectively. The way is to bring together labs that use different
techniques for target preparation and those that can test the target performance under “real” conditions.
For this task ECOS will have the duty to organize the collaboration and exchange of expertise on the development of high power
target technology
Task 2 Synergies in Super Heavy Element Research
The study of Super Heavy Elements (SHE) is one of today’s most challenging interdisciplinary research fields. It brings together
nuclear physics, atomic physics, chemistry and theoretical physics. Over the last years researchers from the different disciplines have
continued to strengthen exchange of ideas. The ECOS community proposes to use this Network in order to enhance synergies among
the research groups on a European scale.
For this task ECOS is aiming for bringing together the groups with research activities on SHE using high intensity ion beams for an
exchange of new ideas and techniques related to the use of very high intensity stable beams.
Task 3 Organisation of bi-annual ECOS Workshops
In order to optimize resources, two workshops will be organised with parallel sessions dedicated to all aspects of the technical
developments and research activities using stable ions beam facilities in Europe. The second workshop will be coupled to the NA
town meeting
Task 4 Coordination of stables Ion beam facilities in Europe
This third task is aiming for coordination and organization of the network.

The ECOS Network Activity in the ENSAR
framework of the EU FP7 program has among
others with its Task 2 the objective to promote
synergies in the field of Super-Heavy Element
(SHE) research, described as follows:
"For this task ECOS is aiming for bringing
together the groups with research activities on
SHE using high-intensity ion beams for an
exchange of new ideas and techniques related to
the use of very high intensity stable beams. In
particular, Task 2 will propose an optimisation of
resources (beam time, target technology,
detectors) in the field of SHE research among
TNA facilities."
The ENSAR-ECOS Workshop on FUture SuperHeavy Element Strategy – FUSHE 2012 is one
very important milestone in this process. It will
provide a forum for the SHE community to
discuss and define the future strategy to reach
the common goal – the establishment and
investigation of the region of spherical shellstabilised super-heavy nuclei – the so called
“Island of Stability”.
FUSHE 2012 May 13th – 16th 2012
Workshop Structure and Goal
•
The workshop
- attended by  90 participants from all institutions involved in SHE research
worldwide –
was organised in 7 x ½-day sessions with a strong emphasis on discussions
including Theory, Experiment and Instrumentation arguments
 The sessions were organised as a combination of invited talks followed by a
topical discussion for the subjects:
 SHE Synthesis
 Nuclear Structure of SHE
 Chemistry
 Atomic Physics and Alternative Approaches

As a main deliverable of the workshop a paper laying out the – near and far future strategy in SHE research will be produced and published
