PS machine report K. Hanke:

- 87.4% PS uptime this week. Most significant down time from RF glitches and injectors (L2, PSB). Once again the F61 vacuum window was exchanged. Many ongoing MDs. A new nTOF cycle has been prepared. Reduced losses allows to reach 830e10 ppp. nTOF collaboration to define when this cycle can be used for production. Should also work on the parasitic TOF.

SPS Machine report F. Velotti:

- 91.1% SPS uptime. HiRadMat 1h02 in dedicated mode. About 12h from injectors. 3 hours stop today to tune the RF 1 turn phase adjustment.

EA users tour de table:

T8: IRRAD & CHARM G. Pezzullo:

Beam profiles good since last F61 vacuum window exchange. 2 new experiments installed in CHARM.

 

T9: BL4S: Successfully completed the preparation run, ready to welcome the highschool students in September.

T9: ALICE FOCAL T. Chujo:

Installing, experiencing some problems with the DESY table controls. J. Bernhard someone from EN/EA will come and fix. 

T10: ALICE TOF& ITS P. Martinengo: run was successful. Will share the beam between ITS and TOF during the 3 week long run starting next Wednesday.

T10: eAstrogam N. Mazziotta:

Installing. Received the gas for the C-detectors. Will need He for the He bag. 

 

T11: P349 D. Grzonka:  A whole set of new detectors for the polarised p-bar production measurment. See slides:p349-psuser-19072018.pdf

nTOF

The experiment received contaminated samples, had to revert to natural sample with lower isotope content. Need to optimise the running, therefore it would be beneficial to have time estimates of stops published on CPS vistar page, as to plan the calibration runs during down time.

 

NA users tour de table

 

H2: NA61 E. Kaptur:

Beam at NA61 target changes be 0.5-1mrad when supercycle changes, this is problematic as requires retuning. J. Bernhard: The optics should be rather robust and the reported angle changes seem huge. Will be investigated.

H4: SHiP Muon & Charm E. Van Herwijnen: Running at 2e7 pot/spill. Rates are understood:

- Trigger rates 2 times higher than from MC estimations. 

- Muon rate about 1.6 times higher as estimated from simulations. 

Aim is to collect ~1e12 pots, equivalent to the MC sample. Change to the CHARM production experiment on Tuesday next week. 

H6: ATLAS ITK / AFP A Rummler:

Ongoing test of assemblies with new RD53 chips, and different DAQ options. AFP will install in H6A, same location as last time. Will need an XSCA table. The devise tested will be the timing detector to be installed in TS2. 1 AIDA type telescope available for CMS, the other (ACONITE) for HGTD. Other XSCA table will go to RD51. 

H6: CMS N. Deelen: Good progress on the telescope and cooling. Will move out when the Desy table will be needed by Alice Focal in H8. 

H8: LHCb H. Schindler: Run completed successfully. 

H8: Crysbeam G. Cavoto: 1st data looks good. Would like to use 300GeV/c beam for 2 shifts. It is agreed to change to H8:300GeV/c H6:-120GeV/c on Tuesday 11AM, till the MD.

H8: eAstrogam N. Mazziotta: Same setup as now in T10. Will use e-beam.

K12: NA62 N. Mirra: Experiment is running well, continuing with 21 units on T10.

M2: COMPASS A. Vauth: COMPASS is doing well.

 

AWAKE E. Gschwendtner: absent

 HiRadMat F. Harden: The run of the new LHC collimators was successful, only used 1h in dedicated mode, thanks to operators diligently switching between HiRadMat & FT. Original estimate was 3-5h in dedicated mode.

Safety A. Desmarest:

Submit your ISIEC in time, not on the last day before your beam time.
