ACCSYS Project – Status Report for September 2015
1.
TOTAL ACCSYS PROJECT STATUS
1.1
Executive Summary
The ACCSYS project continues to work to the schedule with large contracts
near signature, work continuing on in In Kind Collaborators and the further development
of IKC Heads of Agreement. Final touches were put on a Accelerator Division
reorganization in which the Lead Engineers and some Work Package staff are gathered
into accelerator technology groups such as the Linac Group. This is in response to a
recommendation from the annual review and should allow better integration of the
beam line components. Our quarterly Technical Board meeting was held. Topics
included: alignment plans, Work Package highlights, IVDR status, presentation of the
proposed reorganization and the baseline lattice. Final details of the 2016 budget were
also worked out during the month.
The IVDR review for Spoke cryomodules and the PDR1 for the Accelerator
Cryoplant were held on schedule in September as was the CDR for the L3 IOT.
Numerous staff from ESS and our collaborating institutions presented
papers at the 2015 SRF Workshop. A tutorial on cryogenics and cryomodules was also
presented.
Highlights from work packages include: finalizing the new release of the
linac lattice (WP2), testing of prototype#1 by SDMS (called “Germaine) by Uppsala in
the horizontal cryostat HNOSS. Measurements showed that there is an issue in the RF
pickup line: Uppsala team found out that the pick-up antenna was unscrewed and they
fixed it (WP4), The copper coating process of the power couplers is being qualified in
different suppliers on samples before coating the final pieces (WP5), Kick off in Bilbao of
kind contribution for normal conducting RF held (WP8), Detailed list of vacuum
instrumentation for the ion source and LEBT was created and sent to Cantana for
approval, after that, ESS will buy the hardware. (WP12) Working on text related to
Safety and RAMI deliverables to be included in various IK agreements. (WP13), Working
with Bob Lench (CF) on the requirements process used by CF/ACC for electrical systems.
(WP15). Assisted RF group with different cooling solutions for the stubs. (WP16). The
HoA between ESS and Elettra has been completed and sent for signatures. (WP17).
1.2
Project Wide Issues & Mitigations

RFQ for 3rd party support, i.e. framework / call-off agreement with one of
the notified bodies in Sweden, is delayed. ACCSYS requirements are clear
and stated in writing, however as an integrated approach for the entire
ESS is foreseen the requirements from other divisions have to be taken

into account as well. For WP11 and also WP4/5 such an agreement in the
very near future is very important.
Need for a mechanism to establish service contracts for activities such as
hoisting and rigging
Installation planning sees major issues with wish to install in tunnel
(assembly and test) and transport of equipment into tunnel in the same
areas
Need of common ESS requirement(s) on cable radiation hardness (can
drive cost). ETB is now giving work on “standards” priority.

Focus for the next 3 months
During October - December of 2015, ACCSYS will continue technical work and planning
associated with the existing work packages. Work on IKCs will continue with an
emphasis on the writing of detailed technical appendices and the signing of final
agreements. CDRs for the RFQ and MEBT components along with the second PDR and
HAZOP reviews for the Accelerator cryoplant and the PDR for the LWUs are planned.
Selection of the Test & Instruments Cryoplant vendor is expected. The installation of
equipment in the new RF integration lab at LU will be a major activity. Implementation
of the new line organization structure and other Annual Review recommendations will
continue. Planning for installation and commissioning activities will continue.
Recruitment efforts will continue.

2.2
Variance explanation
Accelerator Project is Behind Schedule and Under Budget.
However, there is no impact on final delivery on-budget and on-time due to the present
CV and SV values. The bulk of the schedule varience is due to a late invoice from the
Accelerator Cryoplant vendor (7.2 MEuros) this is expected in October and the vendor is
on schedule to meet all their delivery dates.

PLANNING STATUS



4.
Several paths are close to the critical one identified. In particular, they include
the delivery of RFQ, MB and DTL.
The detailed installation planning study is on-going inside the accelerator
integration group. A really preliminary version is available in P6.
The development of high level “Ready for Installation” for components is
underway.
COST STATUS
4.1
Variances for at completion budget
The cost objective for ACCSYS is 512 M€. The plan until EOC now shows 512 M€.
5.
RISK STATUS
5.1
Changes is Risk Status during the month
Two new risks were added this month to the register
•
“The ESS designed 660 kVA modulator doesn’t meet specifications and
more standard commercial items have to be purchased” – potential cost
risk of up to 6 MEuro
•
“Venting of Helium into tunnel causes ODH or other hazards” – safety risk
These new risks formally document existing risks and recognize that the EES
designed modulator is the baseline choice. Treatment plans are being developed for
both these new risks.
The probability of one risk was reduced this month:
7(31)
Document Template
Document Number ESS Monthly Project Status Report
Date
2015-10-22
•
“Installation & commissioning is time consuming or results in defective
components”
The probability of this was reduced from 65% to 35% due to the new schedule in
which we have access to the Front End Building and Gallery 9 months ahead of
schedule – this significantly reduces schedule risk
A mechanism for capturing positive cost risks (i.e. opportunities) has been found in
Exonaut. This involves identifying cost risks with negative numbers thus lowering the
overall cost exposure – Response to an Annual Review recommendation

Highlights for the WP this month include:
Peo Gustavsson and Walter Wittmer visited ESS Bilbao on the 15. and 16. Of
September. Discussed where the in-Kind contract for the MEBT for WP 11.3, the
planning of upcoming CDR’s and communication between ESS Lund and ESS
Bilbao and the role of the WP 11.3 team at Lund.
Frank Hellström and Walter Wittmer visited LNS Catania on the 29. and 30. Of
September. The main topics of the discussions where the in-Kind contract for the
ISRC and LEBT WU 11.3.2, the detailed schedule and the L3 beam line interface
between the LEBT and RFQ.
On the 22 the CEA team visited Lund. As part of this visit the in-kind contract for
the RFQ was discussed. A first draft was presented by the WP 11.3 team and
working visit at CEA agreed upon from the 5. to the 7. of October.
A study was initiated to investigate the possibility of pulsing the corrector
magnets in the DTL. In the positive case air-cooling would be sufficient for the
magnets that would significantly simplify the integration into the drift tubes.
Further progress on L4 interface requirements has been achieved. Agreement
has been reached between ESS and its in-kind partners concerning the design
defining requirements.

Prototype cavities:



Prototype#1 by SDMS (called “Germaine”): The cavity was tested by Uppsala in
the horizontal cryostat HNOSS. Measurements showed that there is an issue in
the RF pickup line: Uppsala team found out that the pick-up antenna was
unscrewed and they fixed it (cavity opening under a laminar flow).
Prototype #2 by ZANON (called “Romea”): The cavity is ready to be baked at
120°C for 48 hours with the new and dedicated blanket system designed for
insuring as much as possible a good temperature homogeneity all along the
cavity during the process. The cavity cryo test is schedule for early November.
Prototype #3 by ZANON (called “Giulietta”): the cavity is presently being used
for warm test of the CTS (version with the long stack of piezo).
Power coupler tests:


The first pair of power couplers assembled on the conditioning test bench has
been baked for 48 hours at 155 °C. A vacuum of 1. 10-9 mbar has been reached.
The whole assembly has been prepared for transportation to CEA Saclay
(scheduled mid October) to prepare for the high power conditioning.
Cold Tuning System (CTS):

On-going tests off the new piezo stack (longer stack) at room temperature on
Giulietta.
Cryomodule:




The aluminum thermal shield has been received and assembled without
difficulties to the vacuum vessel.
The cryogenics valves and the heat exchanger have been received.
The temperature sensors (Cernox) have been received and they will be
calibrated (planned for end October) in our dedicated cryo station for
thermometers calibration.
The thermal screen fabrication is a little bit delayed and delivery is still expected
for mid July instead of end June.
Others


The vacuum furnace for cavity hydrogen degazing and/or cavity heat treatment
was delivered to IPNO. Installation of the furnace ancillaries is ongoing (cooling
water, electrical supply). First operation of the furnace is scheduled for
November. After qualifying tests on samples and “old” cavities, the first
treatment of an ESS cavity (spoke or elliptical) should be possible starting from
January 2016.
The modulator fabrication of the 2.8 MW, 352 MHz, pulsed RF power source is
achieved (by DTI-Sigmaphi). Delivery to IPNO is scheduled for October 22th. A
test campaign off the whole RF source will then take place for about 2 months.

After that, the source will be fully operational and available, well in advance, for
the conditioning of the series of spoke power couplers.
Procurement for the series:

Writing the technical and administrative specifications for the niobium and for
the cavities procurement for the 26 spoke units is almost finished. The issue on
VAT exemption is presently delaying the publication of the call for tender.
Publication is now expected for mid November. Actions have been taken together
with CEA and ESS to solve the VAT issue.

article 3.3 of the PED and the maximum working pressure of 1.43bara required by
the cryogenic supply let a very small range to place safety valves for the protection
of the rupture disc. The risk is limited at the cooling down phase that needs to be
optimized in order to avoid changing the Service Pressure of the cryomodules.

WP6: Beam Delivery Systems
Accomplishments
 The raster magnet system Critical Design Review is to be held on October 8th. A
major effort has been put into preparing a technical data package that completely
covers the system (technical details, procurement and schedule, etc.).
 In terms of beam physics studies, the minimum attainable beam size in the HEBT
was investigated following a request from Stephen Molloy. Additionally, the PBI
taskforce led an interview on the topic of the A2T Proton Beam Instrumentation in
relation to the PBI taskforce. As interviewees, we presented the commissioning
strategy of the A2T section, both the DC quadrupoles and the AC raster magnets,
and discussed the necessity of individual units of PBI.
 The future of the WP06 and in particular the imminent open call for tenders of the
raster system was discussed with Peter Ladd who visited Aarhus University
September 18.

DB Elettronica power station for Uppsala University tested. Some issues found
(see below), otherwise working
•
Kick off of Elettra in kind contribution for Spoke power station held in good
spirit
•
Kick off of Bilbao in kind contribution for normal conducting RF held
•
Many contacts with WP 3, 4, and 5 regarding interfaces. Good progress.
•
Early access to gallery seems to be confirmed.
Issues
•
WP 8 needs re-planning to address the early gallery access, especially this is
important for our partners
•
During discussions with WP 3, 4, and 5 it has become clear that there are
several unsolved scope issues: RFQ distribution, Coupler arc detectors,
multipacting detector, cavity control electronics
•
Scope of Bilbao contribution for distribution system RFQ and for CEA Saclay
contribution RFQ has to change. The boundary between the contributions is
moving and this will move cost between the contributions
•
Unclear who is in charge of the RFQ conditioning.
•
The 704 klystron prototype prices show a risk that the tender returns for the
medium beta klystrons can be higher than expected
•
AD has a new organization. It is unclear who is handling the gallery integration
issues under this organization
•
Hard to complete the handling of the stub design by the RF group due to
unclear boundary conditions and competing requirements – shielding, fire,
temperature

•
Contract with LU after 2016 desired, funding to be investigated
•
Continued problems with getting procurements processed, especially low value
(1-10 k€)
•
WP 8 needs re-planning. This will take time.
•
The in-kind document downloads on the webpage are only pdf, no word source
templates. This is becoming a problem for all our partners.
•
AD will contribute to a Physica Scripta special issue and we have been handed
chapters to organize. There is a clear risk that this will grow beyond control and
fill all available time at the expense of other activities
Current & Near Future Variances in Project Plan


Many PDR, CDR, and TRR were put into primavera before the review but they
are now out of place or out of linking. Mitigation replan
It is unknown when the RF systems have to be ready in more detail. This would
help focus planning and work efforts. Mitigation: the linac group has been
handed this question

The klystron prototype plans show delays. Need to be modified, since the
suppliers do not expect delays – mitigation: modify P6 with planners
Alignment between G milestones and WP 8 plan seems to be missing
sometimes – mitigation: go over the plan

the Test Readiness Review for the spoke cavity prototype has been
postponed due to the delays in RF source delivery
new (later) delivery dates for the modulator and the klystrons will require an
adjustment of the TS1 planning
WP11: Cryogenics
Accomplishments

The PDR-1 has taken place on 2-3rd SEPT 2015 at ESS. The committee concluded
that the design appears to meet the specifications and no technical showstoppers
were found. Several recommendations are addressed in the final report.

Critical corrections / adjustments of the long-lead items to be purchased (heat
exchangers, warm screw compressors, cold turbo compressors) were done and
incorporated. Linde Kryotechnik can proceed with the procurement, we are waiting
on their invoice.

The reference points in the cold box have been provided to LKT on 1st October.

The fixed support design in the CTL has been provided to LKT on 11 September.

The new layout in the cold box hall has been received and it turns out that it is
possible to design the transfer line without an additional elbow.

Further progress on OCT documents for warm helium storage tanks.

Progress on OCT documents for warm piping system and installation as well as on
overall flow sheets.

Update of cryo naming convention with some more equipment names and stringent
numbering.

Translation of AFS documents, relevant for the cryogenic system, triggered. First
document is finished. This brings us in a much better position for understanding the
authorities requirements during the operational phase and what to prepare now in
the construction phase.

Meeting between cryo section and quality devision to address safety valve testing
requirements during the operational phase and compatibility with our operational
schedule. Decisions have been taken on where defensively double safety valves are
needed (warm and cold tanks) and where not (CDS) with still some uncertainties
(coldboxes, compressors) which will be looked in more detail with regard to checking
period and impact on operation / required shut-down of sub-systems.

information to make it consistent with TMCP technical specification ESS-0034501.


Researched data on cryogenic turbo-expander failure rates, and sent information to
Alex Garcia (target project RAMI guy) for his reference. We will continue meeting to
further discuss TMCP RAMI issues.
Issues

The end box of the CDS for the spoke linac sticks into the DTL section. Any potential
clashes are being investigated.

The technical annex to the HoA (and IKC agreement) between ESS and CNRS has
not been agreed yet (the recent modifications proposed by CNRS were not approved
by ESS Legal Office)

Design phase of the CDS for Spoke Linac has not started (rescheduling of the CDSSL project will be discussed with IPNO on October 20th),

Revision of Option 1* (cost update, integration of future backup-compressor system)
is delayed, but expected in October

Cost for improved sound isolation of cryo compressor building G.04 not yet clear and
who pays is also not yet resolved. Sound hoods for the compressor skids are not yet
completely excluded but highly unlikely for different reasons.


Potential delay in of CDS-EL detail design package (until end of October 2015) which
may cause the CDS-EL CDR to delay into early next year.
Please note that the design and procurements of the ACCP and its long lead items
are on track. We are only missing the invoice from Linde and so it appears to be a
delay but it isn’t!
Currently no change in “Ready to install dates” expected.

safety aspects within the entire ESS project. Currently ACCSYS project (Safety
work package) is discussing detailed planning to support the licensing process
with the Swedish radiation safety authority. Status is reported at the ACCSYS
weekly management meetings.
Organized a meeting between Max-IV and ESS safety representatives to discuss
licensing processes with the Swedish radiation safety authority. Objective was to
gain knowledge from Max-IV project (see meeting minutes ESS-0039121).
Conclusion was that the meeting was useful and we should continue with regular
meetings in the future.

The project plan has finally been reworked to include the signal cabling and
racks. In addition to this, the plan is now better aligned with the actual deliveries
so that these can be linked to our RFI dates. This was not a small amount of
work for our planners, Lena Gunnarsson and Luisella Lari, who were really
helpful despite the extra load this placed on them. We appreciate their assistance
– and their patience.
Grounding system

Nothing new.
Electrical systems

WP 15 is working with Bob Lench (CF) on the requirements process used by
CF/ACC for electrical systems. CF desires to set a new baseline (ACC system
engineers, via Eugene Tanke, are involved).
Cabling and Racks



Meetings held with ICS, HPRF, PSS, INFN (Catania- Ion Source) and MPS groups
to discuss space allocation, cooling-, power-, backup power and EMC-shielding
for racks. The information collected will be used to guide the revision of the rack
standard document and rack procurement.
Meeting with Rittal (one of the possible rack suppliers) about cooling, that has
led to the conclusion that the current cooling concept is very likely to change.
The duct bank for the cables from GSA to A2T has been redesigned, due to the
decision that GSA should house the least possible amount of electronics.
Issues


We need to create a new requirement for CF stating that cable ducts shall be
provided for PSS, MPS and ICS-signal cables installed between the Accelerator
Building and the A2T Area in the target.
Ambiguity on acceptable cable insulation materials. Decision to be taken from safety
department.
Current and Near Future Variances in Project Plan


Work unit deliverables need to be linked with “Ready For Installation” (RFI) Dates in
the P6 plan.

MEBT-WTRC interface requirements are uploaded into DOORS.
o Phone meeting was held 20150928, where ESS Bilbao stated that they don´t
want to be constrained by water, ESS is complicated enough. Further
discussions are planned for in October. ESS Bilbao has no experience
operating their equipment at 30 °C and they cannot test at this temperature.
Started working on presentation for DESY energy workshop in October.
Started doing some planning for the PSI workshop regarding energy efficient proton
drivers. Had phone meeting with Mike Seidel.
Discussed WTRC-IS/LEBT requirements with Frank Hellström, Aurelien, Georg Hulla,
Edgar and INFN Catania.
o INFN Catania will test their solenoids at 30 °C and in case degradation in the
magnetic fields are shown then we will look into two options; i) new
solenoids, or ii) reconsider cooling temperature.
Met with Michelle Everett and Fredrik Bergstedt regarding cooling water for labs and
instruments halls. Discussion was mainly about interface locations
Assisted RF group with different cooling solutions for the stubs.
Discussed instrumentation with Jonas Widing, section coordinator electrical design
in design and integration support division.
Worked on Klystron gallery cooling water P&IDs. MBL and HBL sections are first to
be drawn. Tunnel and Test stand P&ID will be started somewhat later.
Attended ACCSYS technical Board meeting
Attended several kick-off meetings and phone meetings with suppliers of loads and
circulators
Have met several times with Luisella and Lena to
o Implement and discuss re-planning
o Implement procurement template
o Align with staff plan
o Aligning with other WPs
Met with Anders Pettersson and Alexander Holmes from the sample environment
team in scientific activities division. Discussed needs for cooling and location of
interfaces. Sample environment requires a “utilities manifold” by each instrument.
They need to be highly flexible since each instrument will be used to look at very
different types of samples.
Selection of sustainable materials

A meeting including procurement and in-kind office was planned for put was
postponed. The plan is out for review and can hopefully be released soon. The plan
is to meet people/work packages in small groups and discuss implications and
support.

WP17: Power Converters
Accomplishments
1)- 330kVA modulator prototype – Ampegon contract
The modulator is under construction phase. Due to the problems found with the high
voltage insulators of the high voltage transformers, the contractor has decided to
change the design and use other types of materials. Tests with the new insulators have
to be done in order to check if the insulation withstanding capability is appropriated. The
production of all components related to the HV oil tank assembly (tank, frames, etc.)
have been postponed until the new transformer is validated.
2)- Reduced scale modulator prototype
Four offers have been received for the tender related to the construction of the HV oil
tank assembly.
Three offers have been validated from the technical and commercial points of view. The
winning company was AQ Elautomatik AB, located in Lund, for the short delivery
schedule and lowest price (below our estimations).
A meeting was organized with AQ Elautomatik in order to coordinate the manufacturing
process. ESS has asked the company to manufacture 5 parts amongst the most difficult
ones to be machined in order to qualify their subcontractors.
