1. Post-mortem of shutdown work (R. Brown)
Due to the cooling water problems (see PSMB meeting
of last week), it was not possible to complete all the programmed magnet tests
in the PS Ring. R. Brown presented slides
listing day-by-day all the problems encountered during the 2 weeks' test period
and concluded with ideas for the future. He pointed out the lack of time in
case of a serious problem. The PSMB agreed that the test period is too short
and should be extended by one or two weeks, and based on the experience of
the last years, a schedule should be made (including a safety margin) for
the whole PS Complex and regular follow-up meetings (weekly, or daily; depending
on the evolution of the tests) should be organized. A coordinator will have
to be nominated (Action S. Baird). Now that the shutdown period is
longer than before, the work will have to be organized differently and J.P.
Delahaye encourages all the PS Group Leaders to think about this subject.
2. Follow-up of previous meeting and matters arising
- Meeting DG - PS Management : following an earlier exchange
of views (October 2001) the PS was the first in the series of the divisional
meetings with the Director-General. This meeting took place last Friday,
12 April 2002. After a presentation of PS Management's main concerns, in
particular on the Sector reorganisation, by J.P. Delahaye, the DG replied
to main issues raised and explained his ideas on the reorganisation of CERN.
Following this meeting, J.P. Delahaye recalled the mandate of the PS and
SL/OP groups for studying the location of the new Control Room, if possible
on the Meyrin Site. A written proposal on this subject is required soon.
- Administrative Meeting : will take place this Wednesday 17.4.2002
on Staff Review for career paths A to E. The proposals for ESPs (Exceptional
Service Premiums) are to be sent to J. Boillot by Tuesday 16.4.2002 at the
- Review Committees : J.P. Delahaye announced the Memberships of the various Advancement Committees (SSAC, TEACC, etc.). The list will be published in the weekly bulletin.
- Individual Training Plan : this year's MAPS exercise is well underway
and J.Boillot reminds supervisors of the need to provide the data by filling
in the Individual Training Plan sheet as requested. If it is in paper form,
the Group Secretaries could enter the data into the database.
- Research Board : J. P Delahaye reported some points of the Research Board which took place on 11th April 2002.
- n-TOF : a Memorandum of Understanding is under preparation
: n-TOF 2 was authorized for a total intensity of 1018 p.
- ISOLDE : the recommended 80 shifts were accepted. This results in
a backlog of 500 shifts in total. For 2002, 350 shifts are scheduled,
where both spectrometers (GPS and HRS) will be used in push-pull mode.
The RILIS (Resonance Ionisation Laser Ion Source) is used for 50 % of
- HARP : results will only be presented at the next SPSC. The Committee
insisted on the fact that HARP will not continue after 2002.
- NA60 : due to detector problems they may not be ready for the lead
ion run in September.
- The DG presented the cuts in the physics programme and on R&D.
The users complained about the severe cut in physics and are prepared
to help CERN by finding other funds (e.g. EU funds).
- 120 MeV H- Linac (first part of SPL): using this (room-temperature)
Linac as PSB injector would lead to a substantial performance increase.
M. Spiro of DAPNIA, Saclay, may offer help on this project in the framework
of an EU collaboration.
- 90 MCHF advance payment by Switzerland : 22 MCHF of interest will
be saved : could this be used for R&D?
- K. Schindl informed the PSMB that the Laser 100 J, 1 sec repetition
rate, for the Laser Ion Source has arrived Monday 15 April 2002 from Russia.
- PIL/LEIR : C. Wyss asks for a detailed list of 2002 expenditure
before releasing funds for these projects. Action : S.Maury
- AD "baby-sitting" : the wire chambers of the AD ejection line could be equipped by a remote observation system like the one in the East Hall.
- Startup : no major problem with the startup of Linac and PSB. An
excellent intensity level (for ISOLDE) was achieved on schedule.
- Magnet tests : the uncompleted magnet tests (see point 1 of the
Agenda) have been scheduled for Tuesday 16 April from 8 a.m. to 4 p.m.,
so no PSB beam will be available during that time.
- Robots : the two ISOLDE robots are now equipped with new individual
control units delivered and installed by local companies. The programs used
these units have been revised and further improvements are underway. This
work forms part of the ISOLDE consolidation project and the objective of
these actions is a more reliable operation of the robots.
- NuFact : the liquid target test took place on Saturday 13
April 2002. One more test was scheduled for Monday morning (15 April 2002)
to measure the momentum transfer between the incoming proton beam and the
4. Report from the LHC Technical Board
K. Schindl presented a summary
of the LHC TB meeting of 9th April 2002, including the reports of the
various sub-committees. Of particular interest for PS division was a meeting
of the LCC (LHC Commissioning Committee) on the LHC Ion Programme. It became
clear that the performance with lead ions will be rather marginal due to various
limiting effects, but that the users insist on the importance of a high luminosity.
As for the other (lighter) ions, there is no clear answer yet on the guidelines
to follow. The overall ion project is not yet mature and therefore needs a
Project Leader and a comprehensive Design Report. A review of the LHC Ion
Project (organized by C. Wyss) with external reviewers will be held later
