20. Conclusions LS2 A few points identified as potentially problematic:
Distribution of cryogens in AD during fixed lHe line installation to be detailed
East Hall: CLOUD operation with cosmics: EL and CV availability not guaranteed
NA62 access control during refurbishment: free access ? ->RP
EHN1 extention NP02/04: cooling water requested throughout LS2. Local solution to be considered (closed loop ?)
COMPASS and NA61 may need cooling water earlier than planned availability (if physics program approved)

During LS2:
Complimentary measurements for Run 1 required (intermittent periods).
Laser and electron beam only + plasma cell and diagnostics
main requirement: laser mode, electron beam mode
need SPS access system (approved in PLAN) + standard infrastructure (CV, EL, …)
Coordination with AWAKE and BE-ICS already ongoing.
Note: preparation for Run 2 (not approved yet) not yet included in LS2 planning  will come…

23. Constraints
Need at least 1 month of cold check out with stable beam before taking protons
Cannot start cold check out until water cooling is operational
Not before 22nd February due to other priorities
Consequently ISOLDE low energy physics can only start after Easter 2018

25. Comments
Still awaiting information from different support groups for LS2 operation with stable beam/long-lived RIB (and MEDICIS operation)
Operate from mid-November 2018 – end of year with imported sources (Ti-44 and Be-7) for which shifts have already been allocated. And stable beam
Initial feedback from the INTC puts higher priority on starting up with stable beam as early as possible in 2020.
Re-alignment of hall beam lines
Two new target stations to commission
New experimental set ups will be installed during LS2
Possible issues with MEDICIS operation and civil engineering work for nano-lab during 2018
Adjoining doors need to be condemned and shielded
Little access for transport of materials in and out of Class A lab during 2018
