YETS 2021/22 Update and Latest RB ( 2021 Schedule and ‘Physics Balance Sheet’, NA61, Amber, MuonE, Na64m, CAST, PUMA ) M. Brugger for the EN/EA Group December 8th 2020 Many thanks to all teams involved
YETS 2021/2022 Schedule - Baseline
J. Coupard et all
• LHC orbit closure test in 2021 (w39/40) followed by annual LHC maintenance EDMS 2439145 - version 0.2
• Stopping all beams on 15/11 in order to start LHC in Feb. 2022
• MKP-L replacement needed latest for 2023: available in 2021 -> baseline for 22/23 (13w needed)
• Next iteration March 2021 based on update from LHC Experiments
• FT Physics: focus on high-statistic runs (NA62/COMPASS), M2 pilots and most urgent test beams
• No ions in 2021 -> maximizing proton physics and aiming for early 2022 physics start (LHC & FT)
(optimizing proton availability and allowing for earlier stop)
December 8th 2020 EACM Update 2
ED Discussion & Recent RB
• Focus on ion operation and 2021
schedule/experiments
• 2021
• no ions, present schedules and our strategy confirmed
• 2/3 of usual proton year with current schedule for
AWAKE/HiRadMat/MDs -> ok
• EHN2 / AMBER / NA64m / MuonE
• M2 pilots confirmed as critical input for final 2022-2024
scheduling
• AMBER considered for approval but on a sequential basis,
keeping M2 options open
• CAST:
• can continue for the requested three months
• the 70k (funding for CRG) to be discussed between RCS and the
collaboration December 8 2020

o Intensity ramp up through MDs / beam commissioning
• Requires scrubbing run for each intensity step to mitigate e-cloud
• Requires MDs to master challenging beam instabilities and minimize beam losses
o High intensity studies in 2022 crucial for decision points on further upgrades

No Ions in 2021
• NA61 as main user with 1 + 3 weeks (+ESA/NASA and a few other test beam)
• Setting up SPS FT ion operation would come mostly in addition to 270h slip
stacking constrained by:
• availability of RF experts
Impacts:
• dedicated setup in the injector chain (regular ion cycles as from summer) COMPASS / NA62 /
• DSO tests, tuning of EA transfer and beamlines (few days at least) AWAKE / HiRadMat
• NA61 commissioning (TPC mainly) to allow for 21/22 modification if needed
-> proposed usage of thick target (aiming to verify new readout system – 1kHz)
• Balance sheet: 2021 1+3w, 2022 6w open charm -> = 2022/23 ~9w physics
Clear overall advantage in prioritizing 2021 proton physics.
2022+ options for longer FT ion operation to be investigated
December 8th 2020 EACM Update 7
M2 – Pilot Runs & Run-3 Schedule
• Pilot-run status (NA64m, MuonE, Proton-Radius)
• approved infrastructure modifications on-going
• schedule tight, but feasible for NA64 and AMBER
• MuonE possibly not ready for pilot run for 2021
(final news/decision in January SPSC)
• AMBER: additional infrastructure needs and beamline/target modifications only as from 2023
• target area shielding (needed for DrellYan) [RP limit reached at fence location] -> ECR on-going
(~150 blocks (checking how much we can re-use) + related beam line modifications)
• Funding/collaboration: aiming for overall approval, but not necessarily for detailed schedule
• MuonE
• Final implementation: major beamline modifications, platform & temperature stabilization (0.3deg)
-> to be designed (CEDAR-like) > hostlab (overall AC area?)
• detector cooling focus to be recommended
• Running all experiments and covering required data taking will extend into Run-4. Focus on
optimizing overall Run-3 schedule w/o blocking experiments early on.
December 8th 2020 EACM Update 8
2021 Schedule & FT Physics
• SPS FT: reaching 400k cycles in 2021 (compared to 600k usually)
• COMPASS cannot do full transversity run in 2021 -> 2022 `slot required anyway
• AWAKE: initial request 12w -> IEFC 19.6. 8w -> now at 51d (7-8w)
-> agreed with collaboration -> impacting ~6% of FT physics
• HiRadMat: reduced to 3 slots -> FT physics impact ~1-3% (1% in 2018)
• SPS available intensity
-> ok, but needs detailed follow-up/preparation
• COMPASS: 150@T6
(stability important: 2-3w of stable intensity each)
• NA62: 60@T4
• NA62 dump-mode for a few days (80-90@T6) (ok with TAX)
• would be compatible when scheduled with AMBER/MUONE
• T2 intensities to be optimized (e.g. for NA64)
• ISOLDE: baseline for starting physics June 21st
• AD/ELENA: starting August 23rd (so far no margin)
• nToF: September 27th (advancing well, nToF experiment will start commissioning in July )
• East-Area: October 10th critical path -> T8 operation focus, CLOUD option maintained
December 8th 2020 EACM Update 9CAST – 2021 Request
• June 10th RB: CAST data taking period up to the end of 2020 (total data taking time of ~6 months), but:
• COVID-19 impact (delayed maintenance of the first cooling tower, etc.) -> CAST started data taking on August 3rd
• maintenance of the second cooling tower could not be shifted from October to 2021-> stop data taking between October
9th and November 19th -> data taking time for CAST in 2020 to only 3 months before the Xmas shut-down
• Analysis: improved anti-coincidence technique -> better distinguish EMI/EMC parasites vs DM axion candidates
• Follow-up discussions with SPSC referees took place (ADMX-like analysis)
• 6 months data taking required to cover exclusion area
• 10 PhD students rely on the full data set of 6 months
• Collaboration and their funding agencies have agreed that the
magnet/cryogenic operation cost and the related cryogenic service team
could be financed if required (~70k)
• TE/CRG and other services ok
The forecast of CAST concerning the estimation of the exclusion
plot after having the full 6 months of data taking is illustrated in red
December 8th 2020 EACM Update 10PUMA – Technical Review Conclusions
• Technical review carried out November 10th
• Initial summary provided to EP/ATS management (slides)
• final review report (link) submitted early last week including the updated TDR (link)
• ECRs (AD/ELENA and ISOLDE) in circulation for approval (EDMS #2151516 and #2307820)
• Detailed and successful analysis of all technical aspects (vacuum, transport, etc.)
• Specific discussions (and related TDR update) on pbar/ion transfer/measurement trap
• Review board agreed on a very positive recommendation for an approval of the
experiment in the upcoming RB, provided the required resources can be confirmed
• Remaining funding (1MCHF for 2021-2023) is already part of MTP targets already
considered in the 2020 exercise (no additional request during 2021 MTP exercise, only
remaining uncertainty for 2022/23 depending on Diesel/Crane, likely covered)
Many thanks to all reviewers, involved technical and service groups and the
PUMA collaboration.
