Presentation of I. Leconte
Following notes of discussion during the presentation.
Date of Test of Mod0 is unknown
Mod3 on Section RI: soon coupler installation (in the tunnel). Will need crane for PFN modulator 3 in Winter 2027
Winter SD noisy corings in PINJ
Booster upgrade Winter 2027 if magnets arrive. Summer 2028 full installation if magnets are late.
JG: how many days for magnet removal? Winter SD may be not enough (many days, but few can be used)
IL: 2 teams will work in parallel
Acustic barrier installation at linac tunnel end to reduce noise level in LB1 below the acceptable levels for SAFETY. LB1 should be ok. Acustic barrier will be installed in any case as a preventive measure.
Drilling of LB1 cores is postponed to March 2027 to avoid overlap with removal of crane above quadrupole in booster tunnel.
PC: will test material stored in LB1 to free space for coring activities by removing the material that is no more activated and move it to ESRF 12
ADE: SAT SBand 8th Jan 2027. But can be moved if needed. RF-unit will be delivered in December.
PC: must clearly solve coactivity issues. A separation between linac and cold project installation may be envisaged.
BJ: 2-4th November dismantling of Faraday cage. TBC with planning and company.
SRE connection on Monday (28 September) Should be ok.
2days ok for installation of 2 cranes? + test? Alvaro: last time 1 day but really just enough. This time 2 cranes 3 days.
Crane for PFN modulator 3 waits Winter 2027. No quotations yet.
Can we install Cranes during USM? PC and SR reply: YES, it can be done. Respecting rules and coactivities (EXT+ESRF, EXT+EXT). Can also stop works temporarily is USM priorities demand it.
Maps are shown to safety for the installation of a safety corridor around the Crane installation. 3m from crane to opposite wall. 1m needed for corridor around fenced area. It may FIT. This allows coactivity for works at height in a confined region, but not for noisy works of work with dangerous products, for example.
Some works for preparation of corings could be anticipated to USM (not the coring but the preparation before the coring takes place)
Crane installation will be noisy, but only for small times (holes in the roof).
In the list of corings to be done:
1 Coring LESS as use of faraday cage exit hole for entrance of LN2.
1 coring MORE for LN2 gas extraction (not in drawings yet)
1 coring missing in TZ
Tank-LN2 installation will be modified according to drawings when CFT. Location of tank and pipes not final in drawings.
TB: how much space needed around coring? Some installation (water) presently being put in place is very close to the coring locations. Alvaro will check that there is enough space with F.Favier.
PC: PSS will be modified to allow PINJ works when RIPS is ON.
PC: LN2 extraction will not be enough in case of LN2 leak. Oxygen detector for every person entering the linac tunnel. Modification of infrastructure in time is not feasible. Actual ventilation OK for small leaks.
ALGE could mark position of coring, cranes, etc.? GC: OK to do this before SD.
YG: should find a person that coordinates works with maters planning. For every intervention: name of intervention, Group, person responsible.
I.Leconte accepts to cover this role. BUT: no info in due time -> no works take place.
M.D.: the person responsible should also be at the work location during the works themselves.
