• Cables
  • For suspending the cables SCE has said they can easily attach them onto the scaffolding - however, this would mean they would still require suspension for 1 week as the time it takes to detach the cables, then build scaffolding, then attach cables to scaffolding this would be the estimated lead time.
  • A new on-site visit will be requested in order to see if a temporary frame can be built over the beamline in order to rest the cables on that, but there is limited space
    • If possible / space allows, mechanical protection over the beamline is preferabe as this would then protect even from the construction of the scaffolding itself
• Protection of equipment
  • The idea is this will now be done by RBS. Timeline still TBD.
• Working footprint attached
  • This shows the area that will be worked on taking into account both the dismantling as well as the construction phases
• GPS exhaust vac pipes
  • Re-routing not possible
  • plan b - will design a permanent shielded box
• Dismantling
  • CV
    • require 2 weeks
    • space for 2 pallets for dismantling of AC units and ducts
    • Route for removal of pallets?
  • ACE
    • 3 weeks end of may/ early june
    • green cage and light structure
    • Route to be defined and location of pallets to be defined
• Integration
  • Meeting tomorrow afternoon for revision of current integration
• Planning
  • Carlotta to come up with a master plan which integrates all groups on a weekly block schedule
  • This can then be circulated among relevant groups by management
  • ECR for EP cage change?

14:30 → 14:40 Machne related activities in the experimental hall

Speakers: Erwin Siesling (CERN), Simon Mataguez (CERN)

• request by Daniel Valuch for CV assistance to purge the cooling water system for the SRF amplifiers (in B199). To be checked with Xavier Decrand (retour 26 Jan).
• HIE tunnel visit by Rustan Calming EN-EL: future cable work.
• HIE tunnel BCAM system (MATHILDE) disconnected (Antje Behrens, Alexandre Beynel: BE-GM Survey). Survey planning OK for CM1 dismount (start Mon 2 March).
• Test for fitting of the lifting pins for the CM handling tool today in the HIE tunnel (Mathieu Therasse).
• Replacement of the RC4.FC90 unit foreseen today has been postoned RC4 was under vacuum. VSC (Guillermo Fernandez) wants to be present during the intervention. Vacuum acceptance test to be performed? Opened the N2 bottles for venting process (Erwin). BI wondering who to contact for OP related issues.

14:40 → 14:45 Experiments related activities in the experimental hall

Speakers: Erwin Siesling (CERN), Hanne Heylen (CERN), Oscar Fjeld (CERN)

Ongoing

• Visit has been carried out for the cutting of the ISOLTRAP wall for a future emergency exit: Severin d'Armancourt, contractor, Arthur Jaries, Erwin Siesling
  - position and size have been decided on and are indicated on the wall (ISOLTRAP side).
  - the existing services on the ISOLTRAP side will stay in place and moved down only when the full new platform floors have been installed. The power outlet on the Mezzanine side will need to be moved (action to be taken by E. Siesling). Ethernet cable for the WiFi antenna will need to be moved during cutting and re-routed once the work has finished.
  - cutting of the concrete will be done by carrottage rather than saw and will require blockage of the crane for ~4 days. Transport  to be consulted for the handling part well in advance.
  - activity foreseen mid-April, after CM1 dismounting and transport has finished. Replacement of the ISOLTRAP platform is to start after that (Arthur Jaries).
• Emptying of the ISOLTRAP platform advanced well (Arthur Jaries). Filling line will be installed to the top floor after which transport of dewars to the top floor isn't necessary anymore (will be in place before wall cutting).
• Wisard measurement campaign: Monday 26/1 - 8/2
  • Handling for transport of dewars
• Cleaning
  • Containers (red, blue, cables), scrap metal containers (to be moved)
  • Big equipment plans
    • Gandalph - move out ISOLDE before end of February
    • Edingburgh chamber in HIE-ISOLDE - team is coming here in February to dismantle -> also metal boxes in SAS
    • Miniball clovers - move out before end of January
    • IDS boxes in SAS - stuck in administrative loop with customs, some progress
    • MIRACLS at LA2: before the end of January, still lots of MIRACLS in HIE-ISOLDE area 

Upcoming

• 508 power cut 9th of February for MULTIPAC

  • For multipac: power cut on 9 February

New

• First meeting of a COLLAPS / CRIS platform has taken place. For further development of a concept Vincent Barozier (integration) and possibly Severin d'Armancourt are to be involved. 
• Modification of high voltage cage COLLAPS
• VITO build new RF-line before summer
• COLLAPS ion source work at start of beamline, ~ May

AOB

• Installation of small eco-point near 508
• Cleaning
  • Deep clean last week
  • Weekly cleaning:
    • Réfectoire les Mercredi et Vendredi
    • Nettoyage hebdomadaire le Vendredi matin

14:45 → 14:50 Activities in the primary areas - Coactivity management

Speaker: Joachim Vollaire (CERN)

14:50 → 14:55 Activities in the expeirmental hall - Coactivity management

Speakers: Erwin Siesling (CERN), Hanne Heylen (CERN), Oscar Fjeld (CERN)

• Refurbishment of the power outlets ongoing (EN-EL / James Devine). This will last the whole week. Precautions will be taken no to cut the power for the WISARD setup (ongoing tests this and next week).
• The overhead crane remote is back in the cuboard. PR214 overhead crane can be used by those who have the license again.
• Re-zoning of the overhead crane PR214 in the WISARD area by the transport team (Yann Seraphin) and dewar handling to WISARD on Tuesday 27 Jan.
   
• EPC platform:
  - Construction work of the EPC platform (508 side) ongoing. Crane blockage foreseen next week 4-5(-6) Feb for the dismounting of the scaffolding.
  - Helmets have been moved to the left after entrance to the 1st floor of 197. Final position will be on the new cage of the EPC platform once the installation has finished.
  - Restricted access from the entrance to the hall from the 508 side during the EPC platform construction work. Visits to the hall from the SAS side (helmets available). Estimate until 6 Feb.
• Request Rustan Calming to store 16 racks for the EPC platform already to the hall: Asked to wait until installation starts (no space in the hall). (Erwin)
• Dust from the construction work is provoking false fire alarms: the fire brigade asked to keep the doors to 197 and the old Control Room closed. Signs have been put in place. Reminder: The key for the door towards 197-1 power room is SC40. Nr 33 in the ISOLDE TRAKA cupboard.
   
• Cable activities in the hall: 
  - New power cables distribution for the CHROME RP detectors. New distribution box on the 170 hall wall at the Salve side next to the RP buffer zone. Cables to the HEBT lines and tunnel side (routing through the HIE mezzanine). Partial cabling to the RILIS zone (final installation after RILIS work finishes).
  - Power cable for warming gas bottles (new flamable gas rack outside 170, Rte Einstein side) foreseen in parallel.
  Contact: Jerome Cantet EN-EL-SW
  
  
• Recuperation bins for metal, etc. presently in front of B198 (Cryo) to be moved in front of the (to be) diesel position at B199. With the restricted and difficult access to the IBDRS side this is a more logic and useful position. Thierry Dupont (Cryo TSO 198/199) has been informed and is OK (Hanne).

 

• 508 access road:
  • Installation of concrete slab for MULTIPAC - need to close access road for 4 days - VIC tomorrow 28/1, asked to do this Thursday 29/1 and 30/1 -> I will give feedback based on this meeting
  • remark Erwin: Would this not clash with the recuperation of the old ventilation unit material bins next to 197 as well as with the construction work on the EPC platform (contractors van / material)?
