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)

AWAKE Run 1 Laser dump e- SPS protons 10m SMI Acceleration Proton beam RF gun p Proton diagnostics BTV,OTR, CTR e- spectrometer 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… E. Gschwendtner, CERN

ISOLDE key activities during YETS   2018 Dec Jan Feb 4 11 18 25 1 8 15 22 29 5 Protons off Water Off consignation power supplies used target preparation target removal HT installation Feb Mar Apr   12 19 26 5 2 9 16 Frontend maintenance Water on Deconsignation power supplies cold check out period SEM grid tests (HRS) SEM grid tests (GPS) HT tests with p-beam (HRS only) protons on ISOLDE physics Class A ventilation maintenance

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

ISOLDE Key activities through LS2 2017 2018 2019 2020 2021 Bat J F M A S O N D   179 construction nanolab etude civil engineering connection to existing lab equipment MEDICIS operation LIEBE ? 170 60kV HT installation 1 power supply + modulator alignment beam lines in experimental hall preparation alignment ISOLDE operation with protons stable beam 838 Front End exchange GPS FE removal GPS modification GPS installation HRS removal HRS modification HRS installation Robot check out commission GPS and HRS

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
