ISOLTRAP:

• Work started Thursday 18/06 with the scaffolding and removal of the alu staircase from 1st to 2nd floor.
• VITO laser beam pipe integrated in the scaffolding
• Removal of the 2nd wooden floor and installation of the alu new structure, floor plates and 'garde-corps' went according to plan and is all in place.
• Next phase: re-installation of the alu staircase and replacement of the 1st wooden floor for the new alu structure and floor plates
• Timeline: activities until 18/08
• Emergency exit ladder part to be installed (Severin)

WISARD:

• taking data wk27-29 until July 19
• Coordinated with ISOLTRAP & RILIS work.
• Small modification done 07/07 to the zoning of the dewars manipulation for the WISARD platform: gaining ~30cm to move the dewars further onto the platform. This improves significantly the safety (large dewar was on the very edge when craned in place) (Filippo Cappelletti EN/THE).
• Please inform Transport in time when wanting to remove the inner structure (Yann Seraphin).

COLLAPS/CRIS platform:

• COLARIS p;atform 3D integration being finilized as well as laser rooms.
• Discussion on solutions and calculations ongoing with CE for stability and type of pillars for the mirrors.
• Costs and budget alloctaion being addressed.
• AC solutions for the laser labs being looked into (cheap versus expensive verus stability and integration).
• Timeline: CE design and quotation by the end of the summer, ECR ready by the end of the year, start platform construction Jan '27

IDS:

• Solution for the falling plastic not yet in place. Proposal closure of the openings with alu plates: Severin to be contacted

VITO:

• Temporary installation of a HT cage next to the REXTRAP timing rack foreseen for a few months
  
  

Beamlines:

• RC6 MR-Tof installation work continuing (Lukas / Alex)
• Cabling work in the RC6/RL7 area few details to finish as of next week when cable team is back
• Old 9 GAP RF cables going to be removed - in parrellel with RILIS work as of next week.
• RL7 installation work on supports and equipment continues
• Solution found for the AC distribution. Discussion on final AC power cabinet position (next to RL7 or on the wall). Rollable final connection of the 125A lines so no permanent cable tray installation.
• Cable work would start end of Aug wk33/34. PUMA transport not realistic before Sept anyway.
• Installation of new PUMA related RP monitors at the end of the RC6 and next to PUMA (at the Miniball side). Permanent installation (Jerome Cantet EN/EL). Meeting in situ (to be) scheduled for Thursday 16/07 (availability stakeholders (PUMA / RP / Miniball/ Carlotta))

Infrastructure / cooling and chilled water cut (IBDRS related) (dates:  19/08   -  May '27 ?  - news?   ):

• Compressed air to be kept (isolate 198/199 area from 170 area)
• 508 AC will be cut affected: Laser labs 508 will be affected
• Possible solution being studied with flexibles to connect existing chiller over the roof and keep the present configuration of AC for 508 (Alexandre Fournier CV). Transparent to the users and avoids complicated installation of an individual AC unit for VITO (and no AC for other setups nor ICR) - news?
• 170 demi water 27 degrees will be cut: COLLAPS, VITO, PUMA will be affected
• 170 raw water 20 degrees will be cut: Timeline fits with LLRF characterization measurements of the REX RF structures (D. Valuch, G. Piccinini) & Solid State amplifier commissioning as of Sept/Oct '27 (G. Piccinini)
• Timeline should fit with Cryo tests foreseen Q4 2027 in the frame of the integration of the LHe dewar and restart of the Cryo plant - 27 demi cooling water needed (N. Guillotin, T. Dupont)
