Intervention in NEAR and detector calibrations with several sources during the PSB stop on 03/04.
Data taking proceed as scheduled in all experimental areas.
The agenda for this meeting is based upon user schedule v1.0.1, please cf. here.
Planning:
User Schedules v1.0.1 (for most of the lines until July) released: see User Webpage
Please get in contact, if you want to take one of the week still free before June - Tanja (tetiana.shulha@cern.ch) is collecting all requests.
2024 proton run extended by 5 (!) weeks. Waiting for the release of Injector Schedule 2.0 for details about the last weeks.
Proton and Ion beam users: Please add “Exclusion Periods” until 2th December 2024, if you are concerned by this extension.
Very high overbooking, in particular at the end of the proton run
–> Even if the run get’s extended not all the requested beam time can be scheduled !
–> Users scheduled in parallel are often not fully compatible - requiring to operate in ‘time share’ mode!
–> Consider taking one of the available slots in the first half of 2024!
–> The slots which are currenlty marked as DRAFT in v1.1.0 are very likely to be moved by several (order of 5) weeks.
Injector chain - Rough week with several stops. See PS/SPS presentations.
Friday 2 electrical pertubations. Cryo lost at point 6, beam stop for PS/SPS.
Challenging week due to various issues, but okay availability achieved considering (89%)
TOF and EAST parasitic beam settings at standard physics beam conditions.
Intervention in NEAR and detector calibrations with several sources during the PSB stop on 03/04.
Data taking proceed as scheduled in all experimental areas.
T09: Normal operation. Today will switch to electron beams. No issues.
T10: Normal operation.
T11: Off, no user.
Normal operation. Despite issues at PS, quite good week (cumulated >2.5e16 p/w on T8, see plot below) thanks to the new high-intensity EAST_T8 spill. Access on Wednesday adjusted to match the whole day PS beam stop. In IRRAD, exchanged the dosimetry for the experiments started before Easter (iFAST, TE-MSC) weekeknd. For CHARM, BE-CEM components test continue and installed ATLAS and R2E experiments in the target area. We run until next Wednesday.

Easter week:

|---|---|---|
| tilt | ‘ladder’ | temporary fix |
A few more days of beamtime left:
We have a confirmation that we will have the telescope for the test beam. We will need to crane it in the T9 area together with DESY table.
We summarized our primary beam needs to PS coordinators.
We are cheching if the nitgogen disctibution with 10 mm pipe can be connected to our setup, which uses 6 mm pipe.
We filled in safety form.
We will be in toch with Dipanwita for planning of the first day.
For the telescope (Andre Rummler): telescope with exception of planes, fei4 and PI stage was stored in the east area. Other equipment was put into TREC and will be brought over by self transport.
Smooth data taking, took data also during Easter and plan to continue
CANCELED - they will not join as parallel user in week 15
General: Beam commissioning in progress.
H2: Commissioning almost completed. H2-VLE not yet comissioned, tentatively planned for week 16 tbc with SY/BI and only if no user wants the beam.
H4: Comissioning almost completed, H4-VLE XCETs still to be validated by SY/BI. Beam to be handed over to RD51/GIF++ on Tuesday 09.04.
H6: Commissioning almost done. Electron and positron beams being prepared today.
H8: Commissioning proceeding well, steering and focusing complete for main 180 GeV/c beam.
M2: Hadron and muon beam commissioned. Cedar commissioning ongoing. Preliminary scans look good. Some issues still with the FISCs that is being checked with BI.
P42/K12: Beam commissioning basically done, waiting for feedback from NA62.
Apology to missed the meeting, I had problems at the experiment.
Most detectors are ready for the start of the data taking, during the week end we agreed with Johannes to have muon beam needed for calibration of detector.
Next week, we have to understand exactly when, we will fill the CEDAR with Hydrogen.
The detector is ready to be installed next week.
Beam: electrons between 10 and 300 GeV, as wide as possible, rate up to 100k particles per spill.
No strong requirement on purity, momentum spread <10%
Some runs with muons for alignment.
ISIEC has been sent.
Groups:
SETUP A, B: PICOSEC (F. Brunbauer, M. Lisowska)
SETUP C: STRAW (T. Enik, K. Kuznetsova)
SETUP D: RHUM (M. Iodice, G. Sekhniaidze)
SETUP E: TWIN TPC (F. Garcia Fuentes)
SETUP F: GDD/RD51 Tracker (K. Floethner)
SETUP G: USTC (Y. Zhou)
SETUP H: CMS ME0 (A. Pellecchia, P. Everaerts)
Beam: Mostly high rate muons, few pions shifts, NO Goliath
Installation and operation
Currently we are extremely low on person power for the first weeks and also there are issues with the materials necessary to operate three telescopes at once this week (H6A, H6B, T9). We might only start a few days later or even in week 16 but we are trying hard to make it possible.
No main user, incoming parasitic user (see below)
Main goal:
Intermediate milestones:
Current Readiness:
Telescope readiness (Andre Rummler): System is set up although depending on the choices we might still dismount some telescope planes / the FEI4.
Possibility to install for SciFi testing.
The detector is not ready yet and should still be transported from Lausanne.
Check with Maarten.
Nikos : Request if NA64e could start installing earlier (taken from GIF++ beam time)
Théo Moretti: MONOLITH team regarding the maintenance of the UniGe FE-I4 Telescope. Possible inside PPE-156 ? Somewhere else ?
Gerardo Vasquez : SND@LHC proposed move from July to September
