FASER LS2 work coordination meeting
CERN
Attendence: Marco Andreini, Jamie Boyd, Liam Andrew Dougherty, Francisco Sanchez Galan, Brian Petersen, Alberto Rigamonti, Maddalena Maietta, Camille Vendeuvre
Introduction (Jamie)
- updated schedule for S81 cool-down not approved yet,
but expect cool down to start November 20
This would allow FASER installation work w43-w47(partly) and w1-w5 (2021).
* First period will be used to install cooling, crates, cables and magnets
* Not clear if 3rd magnet will be ready in time for 2020
* Second period would be for installation of active detector
components and the support structure as well as commissioning
- Camille found that magnet fiducialisation not correct for 2nd magnet
* Meeting with experts planned for next week
* Will likely require remeasurement. Ideally thi will be done just
before installation to not interrupt work in EHN1
- Commissioning schedule for EHN1 (pre-installation) shown
* Intense four weeks ahead to learn as much as possible before installation
- Detailed schedule for TI12 work in week 43-w47 being worked out
* A draft schedule was shown
* It has been discussed with EN-EL and EN-CV
* Still needs to be discussed with EN-HE.
- Important that components can be tested after installation
* This requires cooling, power and network to be tested and
available from start of week 1
* Had discussion of safety aspects and sign-off procedure earlier this week
* Plan is to have first sign-off on October 30 with final sign-off around week 5.
- Fibers have been installed from TI12 to RE12, but needs to
be patched into existing fibers to SR1
* Would like to have this ready soon to allow early testing to start
- Cable trays have been installed in TI12 by EN-EA and actual cabling
planned for week 45
* FASER now expect to include cables for interface tracker which itself
will only be ready for installation in summer 2021
- Connection from cooling station to detector is being finalized
and tested at EHN1
* Issue with control software being followed-up.
* Diagram of cooling pipe routing was shown
- Alberto noted that EHN1 will have no access on Tuesday 29th September
- Francesco asked if installation of top-plate in TI12 will need survey
* Camille confirmed that he will measure its position and
also use the time to resurvey network (takes 1/2 day)
WP3 (Liam):
- Unused infrastructure in UJ12 has been dismantled and the walls painted
- The TI12 handling rail has been installed and tested
* A small adjustment of hoist to be done tomorrow
* The rail is now a permanent installation, but is easy to move from side to side by hand
- Optical fibers are installed into TI12
- The compressed air installation is on-going - to be finished tonight
- UJ12 guard rail will be installed middle of next week
and in TI12 during week 42, assuming rails are manufactured by then
* Drawings sent to Marco for safety documentation
- Francesco noted that only minor works are outstanding
- Francesco suggested to have painting competition for FASER wall (30x2.4m)
as interesting outreach effort
Next meeting:
- Planned for October 8
