Platform EPC:
- Interconnections racks / patch panels ongoing. Existing HT cable bundles being pulled up. Modification bracket under vertical cable tray: Oscar
- Modification of false floor: leave certain width in front of remaining blue racks (remaining cables). Brianstorming with Oscar.
- Modification passage floor (new beams and metal floor) to be installed at the end of cable campaign.
- Expected delay 3 weeks.
REX/HIE ISOLDE preparations CM1 transport:
- All Cryo services dismounted on the tunnel roof and top-plate (removal flexibles, structure, protection burst discs, etc.).
- XLN03 & 02 vacuum chambers disconnected. TPs removed (point of gravity).
- BI cables disconnection ongoing. Solution for storage (palette/on roof) being worked on (BI).
- Thursday/Friday 26/27 March: Handling intertanks XLN02 & 03 from machine onto palette / roof.
- CM1 Radiological aspects (mainly for the work in SM18): List of isotopes seen by HIE ISOLDE 2015-2025 provided by OP (Simon, Alberto) to RP (Fabio)
- Meeting (SRF, RP, OP, TSO) held Mon 23/03:
wk 13: List of identified isotopes seen by HIE ISOLDE back to OP (Fabio)
wk 14: Response OP on intensities of these isotopes and estimation of losses in CM1
wk 15: estimation RP (Fabio) on what to expect in terms of contamination and activation of CM1 -> Philippe Bertreix HSE/RP transport aspects for the authorities
Info tunnel roof opening & transport CM1 -> SM18:
- Week 16 (13-17 April):
Opening/closing Tunnel roof & CM1 handling in the hall - handling tools and vehicles (cherry picker, etc.), heavy use of the overhead crane
Wall Jura side to be clear of cupboards and toolboxes (access wall top side) -> VITO been informed (Magda, Mark, Nikolay)
CM1 will be standing from 15 - ~23 April in the handling zone next to the yellow RP buffer zone: vibration and inclination sensors + wrapping for transport
- Week 17 (20- 24 April):
Transport CM1 from ISOLDE 170 to SM18 - special transport (truck & trailer) arriving ~23/24 April (tbc). Heavy use of the overhead crane during handling in the 170 hall (CM1 onto pendulum/trailer).
SAS and handling zone to be empty (users will be informed). Parkingt to be empty (IBDRS project been informed)
- RILIS planning kept in the loop (Carlotta Porzio), ISOLTRAP planning kept in the loop (Arthur Jaries)
Planning REX/HIE: 170 REX HIE planning | Document 3383102 (v.1)
ISOLDE cooling water:
- Cooling water stopped since no load
- Requirements:
- REXEBIS: Not until after summer
- CRIS mid-April till mid-May (for lasers and TP's) -> chilled water/AC in the laser room 508 will stay available.
- SRF amplifier circuits (B199) have been purged (Alexandre/contractor)
Vacuum pumping / ventilation:
- For the investigation at EBIS to find an assumed leak its vacuum system will need to be restarted (Guillermo): When will the ventilation system be back operational so the primaries can be restarted? (resume mid-April?)
Work in he 170 HT room:
- Julien Parra-Lopez: Replacement of the GPS and HRS target heating power supplies. Request for handling in week 16 of a few pallettes up to the HT room: Discussed with transport. Will be coordinated around the CM1 activities (roof opening/closing and CM1 handling in the hall).
Beamlines:
- RC6 EN/EL cabling work has started. Estimation 1 week+. No clash with other activities. VIC done.
HRS field control and measurement:
- Request from Marco Buzio TE/MSC to house a full 19" rack. Proposal in ex-entrance 170 R-020 with cables through existing passage (if fits with Ar/N2 and AC tubes).
Discussed at the ICL meeting (19/03). Other position in the new rack next to the new HRS Separator door was brought up but doesn't seem to be an option in the end (CAO beam switching occupation, cable length HRS probes, TE/MSC requires full rack space).
