Minutes of the PS-SPS Users Meeting held on 22nd of July 2021
PS Machine Report (Heiko Damerau)
- See slides
- Good performance until Tuesday morning, Tuesday afternoon cavity repair (2.5 h stop)
- Beam stopper in TOF line blocked since yesterday evening, stop this morning for repair (cool down)
- Beam expected back by 11:30
- Beam to nTOF target Monday at 10:00 as scheduled; beam now at almost nominal intensity
SPS Machine Report (Giulia Papotti)
- See slides
- Problem with P42 persisting
SAFETY (Letizia Di Giulio)
- See slides and flyer attached
- COVID19 self-testing available from next Monday at 10 test stations at CERN, including EHN1 (in the coffee room)
- This is a simple yet conclusive saliva test. Please subscribe.
nTOF (Javier Praena)
- See slides – very successful start of beam period on Monday.
NA users tour de table
- H2 : CMS OT (Dragoslav Lazic)
- CMS OT has successfully completed the measurement in the magnetic field.
- Now other CMS sensors, RADMONS and CERN Proximeters are tested in the field (all without beam).
- H2 : NA61 SHINE (Seweryn Kowalski)
- Currently taking beam – interleaved with finishing of installation.
- Expect to be able to finish the program for the first beam period in time.
- H2 : FASER CAL (Brian Petersen)
- See slides for set-up and beam requirements
- H4 : GIF / RD51/ CMS ECAL
- GIF (Martin Jaekel by email)
- All users could essentially finish their program.
- Pre-dump not yet commissioned (time missing during the beam-line set-up.
- The bending magnet was tested but is not yet conclusive by how much the muon beam can be deviated with it.
- GIF community thanks everybody involved in allowing the start-up to happen in this difficult circumstances!
- RD51 (Eraldo Oliveri)
- See slides
- 3 out of 4 set-up were fully completed. The 4th set-up covered the most important part of the measurement.
- Highly appreciative of the support from all the teams, who made this possible!
- CMS ECAL (Simone Pigazzini)
- E beam set-up and beam monitor commissioning progressing hand in hand, all going well so far.
- LHCb CAL (Matteo Salomoni)
- Handover organized for Saturday. No crane required.
- H6: ALICE ITS3 / ATLAS MALTA / NUCLEON
- Dipanwita: the T4 target was exchanged for a longer target, which will improve the quality of the electron beams in H6 and H8
- ALICE ITS3 (Francesca Carnesecchi)
- Staying on a parasitic user.
- ATLAS MALTA (Ignacio A.)
- Started to take beam on Sunday already
- NUCLEON (Igor Kovalev)
- Will continue with hadron beam until Friday or Saturday
- ATLAS ITK (Andre Rummler)
- ACONITE telescope now 80% operational, setting up progressing well
- Will take pions with 120 GeV/c as in previous years
- Beam position very important (0/0 position)
- H8: ATLAS RPC / LHCb / CMS MTD / FASER Preshower / ATLAS TRT
- ATLAS RPC dropped out due to detector damage
- LHCb
- CMS MTD (Badder Marzocchi)
- Almost finished data taking.
- Will find a ‘parking position’ inside the zone, where the set-up can stay until the next beam period in October.
- FASER Preshower (Magdalena Munker)
- All going well, beam 180 GeV/c pions
- ATLAS TRT (Konstantin Vorobev)
- K12: NA62 (Jurgen Engelfried)
- Ready to take beam; some muons have arrived – started data taking for testing
- Johannes Bernhard:
- P42 set-up and problem investigation for 11 days now, including several accesses.
- After the polarity of one newly installed magnet was fixed, the beam goes a few hundred meters further in the P42 line.
- The T4 target was changed to a longer target, to have less intently in P42 to ease the investigations (allows for a transversally wider beam in the line).
- Suspect still a combination of problems.
- New beam instrumentation will be installed tomorrow.
- M2: COMPASS (Jan Matousek)
- Progressing according to schedule presented last week. Setting up the trigger now.
- Safety clearance still requires some clarifications – urgent now.
- New He3 pipe did not fit. Suspect that the old one did not fit either and that it was installed with mechanical stress, which could explain why it imploded eventually. New pipe now corrected and installed properly.
- Currently installing the He4 pipe and using the time to repair some broken channels.
- AWAKE (Edda Gschwendtner)
- Currently proton beam being set-up to the plasma source.
- HiRadmat (Pascal Simon)
- Facility is ready for beam
- Users preparing their set-up
