Platform EPC:

• Interconnections racks / patch panels ongoing. Old racks removed (except last: holds the vertical cable tray. To be replaced by pillar(s)). 
• Existing HT cable bundles being pulled up.
• 2 blue doors recuperated (under stairs) for the remaining short row of blue racks (2 doors missing).
• Modification of false floor: leave certain width in front of remaining blue racks (remaining cables). Who will modify?
• Expected delay 3 weeks (?)

REX/HIE ISOLDE preparations CM1 transport:

• All top-plate services dismounted (SRF cabling (done by Mathieu Therasse with Daniel not available - many thanks) + tuner plates & coupler motors, instrumentation cabling, etc. (Mathieu Therasse).
• Water and DC for the correctors XLN02 & 03 .0200 (Alexandre Cretin) disconnected.
• This week: Cryo dismounting work on roof and top-plate (removal flexibles, structure, protection burst discs, etc.). 
• Next week:
  Remaining vacuum (XLN03 vacuum chamber connections), BI cables disconnection,
  Thursday/Friday 26/27 March: Handling intertanks XLN02 & 03 from machine into the hall/wooden storage box. 
  To be verified: by BI if Intertank units XLN02 & 03 fit in the wooden box. Check with Transport and VSC if small TPs can stay connected.
  
  
• Discussions on Radiological aspects (mainly for the work in SM18) started: OP will provide the list of isotopes 2015-2025 to RP (Fabio Pozzi) (this week). Isotopes of interest will be identified by RP, OP will then estimate the amount of those particular isotopes seen by the CMs (as per CM4 refurbishement in LS2). Meeting date to be organised next week to discuss between SRF, RP, RP transport and OP.

(remaining info from last week) 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)
  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)

(remaining question from last week) ISOLDE Hall cooling water (27 degrees users Low E side. HIE side: no cooling water):

• CV is facing difficulties with the demineralization as well as general functioning of the hall (Low E user side) cooling water: Decided to stop the system if not needed and collect information for cooling water needs. Restart time and resources will be significant.. Small loads (several kWs) can run on circulating in the circuit without full system operational - load to be defined.
• ISO-House ask around:
  - 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.

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: To be well coordinated with transport around the CM1 activities (roof opening/closing and CM1 handling in the hall).

Beamlines:

• RC6 EN/EL cabling work starting next week for 1 week+. No clash to be expected with other activities. VIC done.
