1. Follow-up of previous meeting and
- PSMB 22.05.2002 : no comments
on the summary of last week's meeting.
- Morzine : a short summary was presented by S. Myers at the end
of the three-day meeting in Morzine and has been distributed to members
of the PSMB. A more detailed summary of decisions taken and suggestions
made is in preparation, subject of course to the approval of the new division
by Council in June. The new AB Division should be composed of nine groups,
and a decision is pending regarding two units (SL/EA - Experimental Areas
and SL/MR - to be renamed Technical Co-ordination). During the Morzine
meeting, the nine groups presented their mandates and proposed organigram
including sections but without giving names in all cases.
Every effort was made to select the positive aspects of each Division
for the new organization. Full agreement was reached regarding the PS/CO
philosophy of maintaining a rigorous standardization of controls. People
dealing with controls should also be regrouped in the new Controls Group
as far as possible, instead of whole controls sections in several groups.
The new Accelerator Group proposes to continue with the present PS system
of machine supervisors with 4 to 5 per machine instead of 7, from the
Operations, Accelerators and possibly other groups. However, this will
occupy each supervisor for roughly 30% of his time instead of the current
20%. No consensus was reached on the ten posts allocated to the Accelerator
Sector for the magnetic measurements and further discussion will be required.
No final agreement was reached regarding a common control room in 2003.
J.P. Delahaye has asked Group Leaders to communicate the results of the
Morzine meeting to the members of their groups.
Several PS and SL groups plan to act as single units immediately whenever
possible, although the official date of the restructuring will be 1.1.2003.
: following the request from the REX-ISOLDE collaboration for CERN to
take over the exploitation of this facility, a PS
technical meeting was held on 30.05.2002 to discuss the resources
needed, in preparation for the meeting with the collaboration. PS needs
an increase in the staff complement of 5 FTEs (full-time equivalents)
and 170 KCHF per year to take over this job. B. Frammery raised the point
concerning the conversion of the REX-ISOLDE controls system which would
come at a critical time (2003/2004). He proposed to check whether REX-ISOLDE
could continue to use the existing controls system and convert to a standard
system as late as possible, in order to avoid a peak manpower request
in 2003/2004. Action : M. Lindroos, B. Frammery.
- CTF3 : G.
Geschonke reported that recombination of electron bunches by means of
an RF deflector had been demonstrated in CTF3 using only half the energy
of EPA (insufficient deflector amplitude), with promising results. Results
are very preliminary (just in time for EPAC) and clearly appropriate studies
have to follow. Congratulations to the OP and CTF3 teams.
- ATRAP : Dr.
Richard Wagner, Director of the Forschungszentrum
Jülich, is visiting the ATRAP
collaboration at the AD this afternoon, including visits to the MCR and
AD control room.
: R. Garoby reported excellent results on improved CLIC accelerating structures
with tungsten irises, which have reached up to 150 MV/m accelerating gradient
(for some 350 MV/m surface field).
- Safety : G. Daems mentioned a safety problem in the AD where
the ASACUSA experiment
intends to use hydrogen. However, originally it was decided that no flammable
gas would be used in AD and, therefore, no flammable gas detectors are
available. It would cost about 200 KCHF to install a detection system.
More discussions will take place this week.
- CAS : a
decision concerning participation in 2002 CERN Accelerator Schools has
to be taken at the next PSMB. Group Leaders should send their nominations
to T. Kehrer by the end of the week for the CAS basic course "Introduction
to Accelerator Physics", Sesimbra, Portugal, 9-20.9.2002 and the
International US-CERN-Japan-Russia Accelerator School course on "Linear
Accelerators", Long Beach, California, 6-14 November 2002.
- PS beam : S. Baird said that it was estimated that no beam would
be available until this evening due to a major vacuum leak in the PS booster,
near the injection septum magnet. The time will be used to determine the
location of the leak, and to decide on a repair strategy. Note that the
leak would be acceptable for proton operation, but has to be fixed for
lead ion operation later this year.
3. Report from the SPSC
J.P. Riunaud presented a summary
of the SPSC of 21.05.2002, which was also attended by J. Feltesse, Chairman
of the SPC. A report
was given on the 158th
meeting of the Research Board and the SPSC considered that a stop of
the PS in 2005 was detrimental to AD experiments. Status reports on the
PS, SPS, experiments and schedules were given. Concerning the PS, HARP has
now started physics data taking with promising results; they have to stop
by end 2002. DIRAC does not get the expected statistics if staying with
a primary beam of 20 GeV/c and, therefore, asks for an extension into 2003.
ASACUSA, one of the AD experiments, stated that a stop in 2005 would disintegrate
4. Status of the PS budget and
new PPA codes
B. Allardyce presented the status of the PS budget. The funds frozen at
the beginning of the year have now been returned to the division. However,
no budget has yet been made available for PIL/LEIR. Everything should be
ready to launch the electron cooling design study and calls for tender as
soon as funds are allocated.
Comparisons of total payments, commitments and project commitments as compared
to the years 1996 to 2001 were given. Spending is under control for the
B. Allardyce also explained the new
PPA codes which will replace the present ones as from January 2003.
The modified CERN-wide codes lack granularity for PS purposes, therefore,
one proposes to introduce sub-PPAs in case of need. It was once more stressed
that when allocating PPA codes to staff members, the limitation to three
codes and a minimum of 15% are detrimental to portraying a correct picture
of the workload.
