Present:
Mark, Gunn, Wilfried and Miguel Baeza
Cables, fibers and racks:
- According to James, all the cable/fiber installation requests (DIC/DIF) for LS3, must be made before May 2024, this is urgent (Gunn takes care of it)
- For DIC, Gunn contacted Gael Girardot, got reply and will follow up (also copy Ioanna Ioannidi, she takes care of most work with Gael)
- Miguel suggested to setup a meeting with Gael and Ioanna, invite him as well.
- For DIF, Gunn will contact Jorge Rodriguez (jorge.rodriguez.fernandez@cern.ch) and Jeremy Blanc
- No DIR needed, during last visit to LHC Point4, we already identified which racks we will use (confirmed with SY-BI group):
@UA43
@UA47
- EN-EL group during LS3 will be very busy with LHC point 1 and point 5 (point 4 is less critical, have a lot more space for cable/racks)
- Mark: can we have triax cables ? How much more expensive would they be compared to standard coaxial ? Miguel suggested we talk to EN-EL
Cooling water:
- Cooling water needed for 10W dissipated heat load (seems low but necessary for removing heat from vacuum side)
- Miguel will find out who is responsible for cooling water in P4 and get back to us
Vacuum chamber layout:
- The vacuum chamber depends on the magnet, we are doing conceptual design study, hopefully get back by end of March with decision on both the magnet and vacuum chamber
- Talk to Eric Page if questions regarding vacuum
Planning and intergration:
- The EDMS doc for HL-LHC BGI integration is constantly updated so make sure to have latest version:
- HL-LHC status integration update and project timeline, see: https://indico.cern.ch/event/1348544/
