1. Follow-up of previous meeting and
- Safety ASACUSA experiment : concerning a possible installation
of a flammable gas detection system in the AD for an ASACUSA experiment,
G. Daems reported that the matter is now in the hands of TIS Division
who will see if a local solution, just covering the experiment, is feasible.
- Electron cooling design study : M. Chanel and J. Bosser are preparing
the papers for a Novosibirsk collaboration for the LEIR electron cooling.
This will be followed by a special technical meeting on the subject. It
has been decided by the Director of Accelerators that the documents for
the global study and manufacture, estimated at 1.5 MCHF be prepared for
presentation at the Finance Committee in December 2002. J.P. Riunaud asked
for a planning of the different stages to make sure that this deadline
can be met.
- LHC-TCC Meeting
: as mentioned at the PSMB meeting of 6.5.2002, the space manager for
the Accelerator Sector, W. Erdt, asked for space requirements for stocking
LHC project equipment. B. Allardyce replied on behalf of the division
that PS had no particular needs. However, following the LHC-TCC meeting
of 17.5.2002, G. Daems said that there was perhaps a misunderstanding
on this matter and that requirements concerned also PS and not only LHC
equipment. B. Allardyce will check this point.
- ISOLDE target area : a request has been received from nTOF to
use the ISOLDE target area (bldg 179) for target manipulations. This would
entail an upgrade of the target area to a Class B safety area. M. Lindroos
is very positive about accommodating such manipulations as, for safety
reasons, it is much better to focus such activities in one place at CERN
and in addition nTOF and ISOLDE will belong to the same group in the future.
nTOF will provide the budget for this upgrade to Class B. The ISOLDE Consolidation
Project foresees a more elaborate upgrade to Class A at a later stage.
- ELEC Meeting : J. Gruber attended a recent ELEC
meeting where, following a recommendation from Task Force 2 and ELEC,
the new structure of the EST-DEM
(Development of Electronic Modules) Group, composed
of three sections (Design of Electronic Modules, Photolithography &
Microconnectics Technology and Assembly Workshop) was presented. Another
subject concerning PS was the increase of licenses for the High
Frequency Structure Simulation software from six to eight.
- PSB : the vacuum leak in the PSB had been repaired faster than
expected and S. Baird thanked everyone who contributed to this repair
outside normal working hours. The effective help from people outside
PS (LHC, ST, TIS) was particularly appreciated.
- nTOF beam parasiting on East Hall cycles : S. Baird proposes
to do a parasitic MD on Thursday to improve conditions so that the slow
extraction gets less perturbation from the nTOF beam. Difficulties are
probably due to running at 20 GeV/c instead of 24 GeV/c. J.P. Riunaud
proposed that MD time should be systematically devoted to tests for any
- Transformer : S. Baird enquired about the repair of the transformer
of the magnetic septum PE.SMH57 in the PS. This is the element that seriously
limits the slow extraction (energy 20 GeV/c instead of 24, fewer cycles
to the East Hall). The repaired transformer should become available by
July 2002. J. Gruber replied that work is on schedule and no indication
has been received on a possible delay. A stop of one day will be required
for the installation. As a one week stop of the East Hall is scheduled
for week 30, this would be an ideal time for installation. J. Gruber will
check on the transformer.
- PS mean radial position : the DSC of the CODD system was rebuilt,
giving rise to a problem, possibly due to a change in the TG8 driver.
Moreover, some PS pick-up stations were disconnected by error from the
analogue signal observation system during the removal of the normaliser
plug-ins. Both faults are being tackled.
3. Highlights of the EMIS (Electromagnetic
Isotope Separators) Conference
M. Lindroos attended the 14th EMIS Conference held in Victoria, Canada
from 6 to 10.5.2002 and gave a summary
of topics discussed, which included new RIB (radioactive ion beam) facilities,
recoil and in-flight separation, ISOL systems, ion traps, experimental systems
and applications. The next conference will be held at GANIL in 3-5 years
time. For the present time and until around 2007/2008 (when TRIUMF's
ISAC II facility,
GANIL and MAFF,
Munich are expected
to start working), ISOLDE continues to be the leading facility in the world,
offering more than 600 isotopes for nuclear physics, and a concentration
4. Meeting on the future of REX-ISOLDE
J.P. Riunaud reported on the meeting
of 5.6.2002 concerning integrating REX-ISOLDE in the next long-term plan
(Council, December 2002) as a new CERN facility. Agreement was reached on
requirements (in terms of manpower and funds) in PS Division, presented
by M. Lindroos, for running such a facility. A draft paper will be prepared
by participants for discussion at the ISOLDE Collaboration Meeting on 24
September and approval at the Collaboration Meeting of 26 November before
presentation at the SPC and inclusion in the long-term plan for the December
5. 2002 CAS
6. PS Information, July 2002
K. Schindl presented a list
of articles suggested for the next issue of the "PS Information",
edited by D. Manglunki. If the authors agree, contributions, in English
or French, should be sent to E. Durieu-Thiry by 21 June. Any other suggestions
for articles are welcome.
