1. Follow-up of previous meeting and
report : M. Chanel distributed copies of the draft PIL/LEIR report
which is also available on the web.
Some chapters are still missing and will be added as soon as available.
J.P. Delahaye asked Group and Project Leaders to read carefully to make
sure that nothing has been forgotten and that they can accept responsibility
for the part that concerns each group. Any additions or modifications
should be given before the end of this month so that the final report
can be made. M. Chanel and S. Maury will arrange a meeting at the beginning
of April entirely dedicated to this subject. Appendices concerning details
on the reflection on different types of sources, individual budgets are
being added and will be available on the web pages.
- DSP recommendations
: J.P. Delahaye (unable to attend the first part of the meeting last
week) has studied the recommendations of the DSP working group and proposes
to accept all the recommendations without further discussion. M.E. Angoletta
will be appointed "Ms DSP" for PS, assisted by the other experts
of the working group, J.L. Gonzalez, E. Peschardt and J. Serrano to help
selecting DSPs/COTS boards on a need-only basis. These people should also
follow up their recommendations on training, seminars and other methods
of information. This proposal was accepted.
- CERN Meetings : J.P. Delahaye said that this is a very important
week for CERN and the division depending on the results of the SPSC (18-19.3.02),
Finance Committee (20.3.02), Committee of Council and Council (21.3.02)
Meetings; the main subject of discussion being the unfreezing of the 5%
of the 2002 CERN budget which was blocked in December 2001 until a detailed
scenario for LHC funding over the next 8 years was presented by the Director-General.
The two scenarios mentioned last week will
be presented to Council. Regarding the 5% which was blocked, three results
can be envisaged : a) the money is unblocked and reallocated to where
it was taken, b) the money is unblocked but the total reallocated to LHC
or c) the preliminary long-term plan is not accepted and a decision delayed
until June, following a probable consultation with the external review
committee. A memo has been addressed to the DG by the division leaders
of EP, EST, IT, PS, SL and ST on the consequences if the 5% if not unblocked
or if it is reallocated to LHC. As far as PS is concerned, the ion runs
would be jeopardised as it will not be possible to run the machines at
the end of the year, and consolidation, maintenance, as well as R&D
will be very badly hit.
- Future linear collider : following a remark from D. Boimond concerning
CLIC, J.P. Delahaye clarified the situation concerning future linear colliders.
Physicists at Snowmass 2001 were
unanimous that the next big machine should logically be a 500 GeV centre-of-mass
Linear Collider which Americans would like to build in the USA with European
collaboration, since they contributed to the LHC. Three studies are at
present being considered (TESLA, NLC
/ JLC, CLIC),
based on different technologies which are compared by an International
Review Committee (ILC-TLC).
The choice of the most appropriate technology and best location is not
yet decided. TESLA is certainly the
most advanced project and aims for a decision in 2003 so that work can
on the other hand is aiming at much higher energies (centre-of-mass energies
of several TeV) and will not be ready to submit a proposal until 2010
- German Delegate to Council : G. Geschonke informed the PSMB that
he had invited the German Delegate to visit CTF and that this visit will
take place on Wednesday (20.3.02). The French Delegate also visited PS
when at CERN for the last Finance Committee.
Students 2002 : the selection of summer students started today
at 2.30 p.m. Supervisors have been notified.
- Seminars PS/SL : J.P. Delahaye is pleased to note that seminars
are now being held in common by PS/BD
and SL/BI groups
(BDI Forum) and encourages this kind of initiative as a first step towards
the accelerator sector restructing.
- Photos PS machine : S. Neboux had informed the PSMB that photographs
in the PS machine taken by R. Brown have been put together on web
pages by J. Belleman.
- ISOLDE beam alignment : until now this task has been carried
out by C. Chollet, PS for historical reasons instead of by the EST/Survey
Group. In view of C. Chollet's retirement, this activity should be
taken over by the centralised survey service which is responsible for
all beam alignments. However, EST have replied that no one is available
to do these alignments and other areas may be also be affected in the
future. M. Lindroos and C.E. Hill have had discussions and meetings with
the Survey Team over the past two months and although a solution was found
for the alignment to be made for the 2002 start-up, a long-term agreement
has not been reached. J.P. Delahaye will address a memo to the EST/SU
Group Leader to state our position: lack of personnel in a centralised
service should not lead to redeploying divisional staff on this kind of
- Windows 2002
migration : B. Frammery said that about 80% of PCs in PS have been
migrated to Windows 2000. PCs previously belonging to EP which came under
the responsibility of PS with the transfer of ISOLDE will be transferred
to the PS inventory and then upgraded in preparation for Windows 2000.
- Server Security : a meeting will take place next Friday (22.3.02)
between members of PS and IT to define a clear policy and respective responsibilities
in the matter of access security.
: J. Gruber attended the Electronic Engineering Committee last week and
will give a summary at next week's PSMB.
- LCC : M.
Chanel attended the LHC Commissioning Committee held on 13.3.02 and it
was decided that he will give a summary of the meeting at the next PSMB.
- Industrial Services : J. Boillot, on behalf of F. Perriollat,
announced that a meeting concerning PS Industrial Services will be held
on 27.3.02 at 10.30 to explain the current situation, the new way of working
and presentation of the teams by the two groups of firms. The invitation
is essentially for the CERN staff requesting work from the industrial
services teams, but other people are free to attend. An invitation will
be sent to the division.
- Team Leaders : on the same subject, G. Daems asked if the mandates
of the team leaders and managers could be clarified at this meeting, as
it is not always obvious who is responsible for what.
- PS posters : B. Allardyce said that about fifty posters of photographs
of PS machines, facilities and installations have now been put on the
walls of the corridor on the first floor of buildings 6/10 and that this
is the end of what can be done for the moment. Everyone is very grateful
to H. Koziol for undertaking the task of choosing suitable photos and
writing the texts. J.P. Delahaye said that the posters are appreciated
by all and give an excellent idea of what has been done in the division
during the last 40 odd years. B. Frammery suggested that posters be placed
also in the corridor of building 8, where group visits pass on their way
to the main control room. Unfortunately, it is not possible to continue
for the moment, but this suggestion will be taken into account for the
2. Follow-up of the PS
complex shutdown work
- Tests at ISOLDE : M. Lindroos presented a possible
scenario for the tests requested at the PSB beam dump and at the ISOLDE
GPS front end during the first day of the ISOLDE start up on 11 April.
SL/BI Group have asked to test an ionisation chamber for the LHC beam
loss monitors in the PSB beam at the PSB beam dump and PS/PP to make liquid
mercury tests at the GPS front-end. K. Metzmacher pointed out that the
new high-voltage power supplies will have to be tested (starting 2.4.02)
and that it is not possible to guarantee that everything will work in
time for these tests. The PSMB accepted and support these tests, but with
the reservations made by PO Group.
- Corrosion : K. Metzmacher also reported a corrosion problem discovered
on the patch panel connecting the PS main supply to the magnets last week.
It is not clear what the problem is, perhaps the insulation, and although
not dangerous it must be cleaned and repaired before the start-up.
- Start-up meetings : S. Baird said that because the PS
is starting up one month later than the PSB this year, there are two start-up
meetings: Wednesday, 3.4.2002 for the PSB and 24.4.2002 for the PS.
- Linac 2 : E. Jensen said that work continues to check equipment
following the leaks on RF equipment due to the high water pressure but
that no damage has been found so far.
- Hardware tests: these tests start today for a period of three
weeks. The machine is closed mechanically to carry out tests.
3. Operation Support in 2002 (Supervisors, ISOLDE, AD)
S. Baird gave a presentation
on the organization of operation which included a list of accelerator supervisors
for 2002, proposals for 2002 and a longer term solution for ISOLDE EiCs,
AD operation in 2002 and later, and LEIR operation in the future.
- Accelerator supervisors : it was noted that a relatively large
number of supervisors are available for all machines except ISOLDE and
AD. A discussion followed on the role of Technical Supervisors and J.P.
Delahaye asked for more reflection on this point before any decisions
- ISOLDE EiCs : with 2 front-ends fully operational at least 5
EiCs would be needed in 2002. The ISOLDE collaboration and EP will fund
an associate to ensure running of the laser ion source for the whole running
period this year. The ISOLDE physics coordinator has scheduled the same
number of shifts this year as last year even though the running period
is 30% shorter. Experiments in the fixed target programme have, in a similar
way, preserved the number of shifts as in 2001 during the shorter 2002
running period. This practice is questionable as CERN has decided on a
30% cut in the 2002 running period and programme. J.P. Delahaye
will send a memo to the ISOLDE co-ordinator to
inform him that with our limited manpower it is not possible to maintain
the number of shifts in 2002 unless extra resources can be found.
- AD : it was proposed to move to an operation piquet service in
July 2002 like the model used for LPI . Some doubts were expressed on
introducing this during the holiday period and it was felt safer to wait
until September. S. Baird will have further discussions with T. Eriksson
and S. Maury.
- LEIR : a preliminary proposal for LEIR operation from 2003 to
2008 was presented.
2002 : all people nominated by Group Leaders were accepted, lump sum
reimbursement of CHF 2000.
2002 : all people nominated by the Group Leaders were accepted, lump
sum of CHF 2950 for subsistence and registration fee, plus travel expenses
(with a maximum reimbursement of CHF 5000).
