notes
Review panel.
WP01 RF
modulator CFT
or PSI second hand
or Scandinova Buy back
PB prefers scandinova buy back proposal. complete system. old modulator really old. scandinova has difficulties. modulator may be will not run at 4 microseconds. Early scandinova modulators, not the best.
This modulator had also some known breakdown. Reparied but still risk. and no warranty from PSI.
PSI will test before shipment and quite a lot of effort.
modulator can give the pulse, but klystron.
Chiara (CERN) confirms that it would work.
Qing to decide which option tomorrow.
For recruitement: 3 candidates for Digitale electronics engineer.
Any radiation producing equipment has to be declared. Must BE ADDEDD TO FUTURE CFTs.
Diagnostics
Vacuum
Mec. Eng.
PSS cabinets will move water sink.
N.Benoist is drawing the internal part of the tunnel. cable trays to be considered.
WP05
no crane but beam of metal for movement of klystrons.
HPM Installation of QCM? forklift not ok for safety.
BJ use MEDIACO company? robot or rollers. This is authorized
WP06 Operation
planning removal of row material storage
will move to ESRF 11, before summer. The sooner the better.
PB: could make inventory? count how many plates are available.
HPM: ESRF 11 and 12 are temporary?
BJ: yes, temporary, but can be kept forever. Checked by YG and PC.
temporary permission cna be renewed every 5 years.
BJ: in CDR there is a line about reliability / maintainability . Cryogenics are part of it.
BJ: Need to discuss for example in ASDMM how to handle cryogenics. may need group of people for cryogenics tasks.
GLB: can expect some issues. cryogenics not planned at the moment.
design by ISDD, application by IDM, maintenance by Vacuum,
COLD project could be a justification to organize the expertise.
CB: QQ is aware about the issue, but there is no decision at the moment.
Bertrand Pellisier is the reference of for cryo in the COLD project.
Faraday cage is not mandatory to move, said TB.
PW: Need to know from SAFETY if RF-units have to be fenced.
ADE: if faraday cage moved, could simplify installation for example of BOC.
BJ: could move away faraday cage to an other location.
KEeep Faraday cage in place untill Cryomodule arrives and decide then.
WP 07
there will be a new interlock meeting next week.
PB: who will be responsible for interlock hardware. for PSS herve. for hardware interlock who will be responsible?
MD: there is advance.
PB: some one needs to build it.
MD: we need to know exactly ho to collect all interlock. Need to think about centralization and how to work with it.
PB: needs fast interlocks (RF) and slow interlocks (temp , water)
Add this item to the list of actions for WP07.
ADE: could be a part of the task of the COD LLRF.
David Frichet could provide solutions.
WP08
3D scan of the floor and walls.
Planning to install HLS next shudown in May
meeting next Tuesday about FSI.
meet also Markus from DESY (XFEL alignment).
WP10
magnets. new pre-design documents.
50A for quads. (not more than 100A)
GLB
10-15% for cycling will be enough.
if magnet is saturated 15% is better.
CDR:
SL to take Magnets docuemnts and update section
Vacuum for waveguides? piumping port is CF40.
any RF grid? yes. shielding to avoid RF leak to ION pump.
There are minutes attached to this event.
Show them.
