East Area Users Tour de Table

T8 Main: IRRAD/CHARM (F. Ravotti)

Good week. POT above the reference intensity for T8 (~2.5e16 p/w, see plot below). During the day we will update the plot including the CHARM target TID. Target was removed during the beam stop at the beginning of the week. The centering of the T8 beam on the horizontal plane was less good than the previous nine weeks: ~85% for this W35 against >90% in W26-W34.

We are in access today from 9:00. in IRRAD, after the summer weeks where we run mosty the long irradiation experiments, now we have several short one in the pipeline (FOS for ITk, LHCb PicoCal, ALICE FoCal SiPM, CMS HGCAL, etc.). Some of these we are installing today. In CHARM we are exchanging test setups for TE-MPE and SY-EPC. In CHARM we are also testing several types of RFID tags to study their radiation tollerance in the framework of the EU-funded AIDAinnova project.

The RP week (September 18-25) is confirmed and during this period T8 will request a reduced duty-cycle (e.g. we will need less spills than usual, details in the coming weeks). Also the cryogenic run in IRRAD is confirmed from mid-october till the end of the proton run.

T9 Main: EIC ePIC LFHCal (F. Bock)

Good week over all. First part of the campaign finished using HGCROC read-out. Now switching to CAEN read-out. Should be done with the switch by mid-day.

T9 Incoming Main: SHIP (Week 37) (Please Put Your Name Here)

T2	T4	T10	T6	Date
30	54	21	30	19.08.
30	54	21	150	11.09.

General: Problem with public network (GPN) in the North Area on Monday. At some point the network was completely off, so the beam was stopped for about an hour as nobody was able to take data. This also affected the telephones and terminal computers in the control room.

H2/H4/H6/H8: Good operation.
P42/K12: Good operation.
M2: Good operation. The trips in the MS2 MBPL magnet came back on 03.09. (4 trips). This magnet is planned to be thoroughly checked after the deinstallation tomorrow. Low momenta muons checked down to 40 GeV/c.

Smooth data taking since last meeting. Doing further integration work during beam-down times, e.g. ionisation laser full integration into TDAQ in recent days. We will continue at 1 GeV until the end of our run on 16 September.

H6:

Outgoing Main: ATLAS ITK PIXEL (Andre Rummler)

(Sorry, can not stay connected as I have to join the TIOC at 1100.)
After some start-up issues we took very successfully a lot of data with two irradiated 150um Micron RD53B quads at 0° and 15° inclination as well as the with a Micron 100um SCC and HPK 150um quad, both ItkPixV1, at 0°. Bias voltages as well as tuning thresholds were varied. ToT studies were conducted. Unfortunately, after changing to 15°C the two V2 showed bad communication which occurred already previously and has to be debugged offline. Measurement with them will be continued during the next test beam. Tuning software was updated improving some errors. Due to issues with the third batch we dismantled already yesterday night and I handed over this morning to ITk strips.

Main: ATLAS ITK STRIP (John Keller)

Setup is ongoing. Samples have arrived from IRRAD. We will run with Mimosa and Alpide telescopes, and TimePix as a timing plane.
