5. Cooling needs in Exp. Areas during LS2
PS Complex :
East Area :
Demineralized water : Stop on the 03/12/2018 – Back on the 07/08/2020 (For F61 Hardware tests)
CLOUD : Which water circuits are needed during 2019 RUN?
Ntof :
Demineralized water stop ok for the whole LS2 (From the 28/11/2018 – to the 18/12/2020)
Cooling of the target to be kept?
AD : Demineralized water stops :
2019 : 20/12/2018 – 06/02/2019
2020 : 19/12/2019 – 05/02/2020
2021 : 17/12/2020 – 03/02/2021

SPS Complex
North Area :
BA80/81/82 : Demineralized water stopped from the 19/12/2018 to the 11/01/2021 (Magnet patrol to be done before the 19/12/2018 except in TDC2/TCC2,
1-2 day of demineralized water on in June 2019 for magnet patrol in TDC2/TCC2,
EHN2 : Chilled water needed until the 7/12/2018 and then needed from the 14/12/2020.
AWAKE : Needs all the CV services during LS2. Maintenance periods are being discussed between Ans. Pardons and EN-CV

18. Awake Operation without proton until the end of December
Operation during LS2 (Priority) : AWAKE request several months of laser-electron-plasma run BUT
Access maintenance in the SPS (No access system in AWAKE from Jan Apr.19)
400kV maintenance in the SPS (No power for AWAKE from May 19 - May 20)
Cabling activities in BB4 (lock out required, Not yet planned accurately)
Future work :
Dismantling of the CNGS Target Cavern (Scope and planning not validated yet, could be done during LS2 or at a later stage)

19. AWAKE Run 1 during LS2 Courtesy to Ans Pardons SPS BE-CO BE-ICS EN-EL
No controls available
BE-ICS
No access system
Power limited to 90 MVA
Maintenance 400kV, need alternative power source
EN-EL
Cabling in the false floors of BB4 mean no power to AWAKE. EN-EL should release a planning mid-June, identifying when AWAKE can perform measures for run 1.Several periods of at least one month have been requested.
AWAKE
Run 1
No run1 possible
Run 1 when power available (i.e. no cabling in BB4)
Run 1 and/or run 2 with laser, electrons and plasma
Run 2
Can remove shielding and install equipment for run 2 when cabling in BB4 or other works block run 1 (~2months of work)
