ISOLTRAP:

• Platform replacement preparations: VITO laser tube (high section) and tall pillar removal to be organised. VITO has been informed (Mark, Magda, Nikolay) -> Action!
• Emergency wall cutting/carrotage: VIC scheduled for 15/04. Wall cutting/core drilling scheduled for week 18 (27-30 April) (Severin/contractor). Crane needs a lock-out during 3-4 days (after CM1 handling and in line with ISOLTRAP activities but RILIS activities to be checked)
  - Attention: This is now clashing with the foreseen crane modification / RILIS laser tables removal: Suggestion - Dismount the PUMA equipment Friday 24th April and re-mount them in week 19 (4-8 May). The modification of the drum and electrical box and brackets will need time anyway during which the laser tables and ISOLTRAP wall cutting can take place in week 18 (27 - 30 April).
• Preparations mezzanine side done: Ready for CE work apart from cable tray bracket and pipe holders on the ISOLTRAP side - Action.
• This weeks ISOLTRAP filling in coordination with the ISCOOL green cage dismounting.
• ISOLTRAP platform replacement work: 18th June scaffolding - first platform part to finish ~22 July.

WISARD:

• planning to come 15 - 19 June to mount the setup for off line data taking
• week 27 (29 June) to cooldown the magnet
• taking data wk27-29 until July 19
• Verification: clash with ISOLTRAP work? No crane need.

Beamlines:

• Clarification on defined escape routes under the beamlines ongoing (in the frame of the new pillars for the new RILIS barrack). (Kati, Andreas Herty DSO/BE, Letizia Di Giulio DSO/EP, et all.)
• Reminder of compressed air issue at GHM (hissing sound - mail Laura 20/3)
  • Can the compressed air be stopped at GHM and kept at GLM - Guillermo will replace the valve at a convenient moment (after ventilation is back / pumping can be started)
• VITO is preparing move of magnet to 275, timing will be adapted taking into account other hall activities - as of week 19?
• VITO move of equipment
  • Clarify duration and extend - during week 16 (13 - 17 April) the Jura wall side of the HIE tunnel up up until the crossing cable tray needs to be clear for handling (nacelle) in the frame of the CM1 dismounting from the tunnel.
• ISOLTRAP platform
  • Wall cutting emergency exit - wk 18
• Proposal to meet next week to check general status of the hall and see what needs removal before cryomodule - 1 April 16h30
• PUMA - drilling of holes in the floor
