East Area Users Tour de Table

T8 Main: IRRAD/CHARM (F. Ravotti / S. Fiore)

Very good week. POT above the reference intensity for T8 (>2.8e16 p/w, see plot below). The TID generated by the CHARM target was 513 Gy. Since we needed to manipulate samples exposed to very high fluences on Wednesday, all material was removed from the line on Tuesday evening (end of all p+ irradiations) allowing some time from 21:30 for the first ion MD propagating the beam down to T8 (see PS report). The centering of the T8 beam on the horizontal plane was back to the usual values >90% on both axes.

From yesterday access. In IRRAD, we removed the LHCb setup (WLS fibers), TE-MSC and LHCb PicoCal samples and installed ATLAS ITk FOS sensors and EP-ESE (CMS HGCAL samples) for multiple fluence steps. During the week irradiations of nLGAD samples for R&D (DRD3).

In CHARM we modified a test setup by TE-MPE, while SY-EPC and BE-CEM setups continue testing. We continued also the testing several types of RFID tags to assess their radiation tollerance (AIDAinnova project).

After the access, took some time to find setting that delivered us a stable beam. Longitudinal profile unstable (see below) - solved this moring at around 8:00.

The RP week (September 18-25) is confirmed and during this period T8 will request a reduced dutycycle (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.

Incoming Main + No beam: GIF++ (Week 38) (Paolo Martinengo)

Continuing irradiation while preparing for beam
Thanks NP04 for giving us access when needed

H6:

Outgoing Main: ATLAS ITK STRIP (John Keller)

Successful data taking throughout the week. Able to complete measurements of our two primary DUTs (irradiated modules from IRRAD) with enough time to take some data on an additional device. Thank you to the beam operators.

Main: ATLAS BCM PRIME (Please Put Your Name Here)

Set up everything yesterday, with minor adjustments to be done. We have not turn on high voltage yet, as we are waiting for the safety clearance visit this afternoon at 14:30. The plan is to have an access around 14:00 to finish adjustments and safety visit later. No run yet.

Parallel + Incoming Main: ATLAS HGTD (Week 38) (Stefano Manzoni)

Two weeks of test beam to test pre-production ASIC (ALTIRCOA) + LGADS, basically continuation of the test done in August

Quick installation yesterday morning, we had safety check in the afternoon and we have already started the data-taking.

Desired beam intensity around ~10K particle/spills to be discussed with BCM prime (but it seems fine)

Incoming Parallel: PICSEL (Week 38) (Please Put Your Name Here)

H8:

Outgoing Main: CMS PPS (Cristóvão B. da Cruz e Silva)

Overall it was a very good week.

Beam conditions were stable throughout and we were able to accumulate a lot of high quality data. Two minor issues:

  • Over night from Sunday to Monday the beam became a bit ‘unstable’ with the y position of the beam oscillating up and down in successive spills, this effectively pulled the average beam center down and widened the average beam profile
  • Over night from Monday to Tuesday, as previously mentioned, one of the Quads failed so the data taking efficiency was not optimal since the beam was no longer centered on our apparatus.

We used gas for 2 different systems:

  • Ar + CO2 for the standard PPS tracker - about 5 l/h
  • N2 for the ETROC tracker (new system in this week) - about 10 l/h

We finished the Bias voltage scan which had been initiated in week 33 in H6 and initial studies of the data show that the time resolution with the pion beam is compatible with the results previously obtained at DESY (electron beam at 4 GeV).

Thank you for all the support

Ongoing Main: DRD6 IDEA DRC (Roberto Ferrari)

  • Since we don’t have people to run 24/7, we plan to leave data taking running unattended during the nights.
  • We almost finished restoring our setup. We run in the night with 160 GeV muons for debugging/control purposes.
  • Starting our physics program today in the afternoon (still a few minor stuffs to be restored in the CR).
  • A note: about DWCs, as in week 35, we will send and discriminate the raw signals in the CR. If we use the discriminated outputs, strange patterns show up in the DWC scatter plots.

Parallel: BI XBPF (Inaki Ortega)

We are running the same setup we had in T10 during week 35:

  • The new XBPF scintillating fiber beam profile monitor
  • A set of scintillator tiles for investigating a new beam intensity monitor in vacuum
  • A straw detector for investigating a radiation-hard beam profile monitor

Our beamtime in T10 in the East Area was very productive, and in this new beam test, we aim to test the detectors with higher beam rates and energy ranges. We hope to coordinate with the DRD6 IDEA DRC users to secure a few hours of beamtime under conditions favorable to us. We’ll need at least 30 minutes of beam access per day to adjust our setup.

We passed the safety inspection yesterday successfully and are already collecting data.

The XBPF monitor is now in vacuum, allowing us to test the in/out motorization. Everything is working satisfactorily.

Incoming Main: ATLAS TILECAL (Week 38) (Tigran Mkrtchyan & Giulio Usai)

  • Detector modules currently in the garage position in PPE158 and powered on for initial tests and maintenance.
  • Table mechanics repaired, planned movement tests on Wednesday next week when primary user.
  • ISIEC form submitted, Cherenkov gas request to be done today, fence removal and vacuum beampipe installation to be requested.
  • We will check the beam elements signal routing, if all required signals arrive in our counting room barrack.
  • Latest versions of Phase2 upgrade back and front-end electronics to be equipped and tested during this campaign.
  • Physics plan similar to last campaign, first positron beams, muons and hadrons in the second week. Same energy ranges and intensities.
  • Availability of Week 41 for potential beam time/data-taking?

We also would like to express our immense gratitude to the SPS coordination, physicists and technicians for their availability and support of our activities.

H6: Incoming ATLAS MALTA (Week 38)(Please Put Your Name Here)

H6: Outgoing CMS MTD ETL (Murtaza Safdari)

Very fruitful test beam here at H6, as well as at H8 in collaboration with PPS. We were able to study the connections of new assemblies at H6, as well as study the time resolution of a chip of the latest version of ETROC2 at H6. And at H8 we were able to complete the bias scan that started in Week 33 and verify the time resolution results for the scanned ETROC2 chip + LGAD assembly. See slides 4+5 of the attached slides on Indico for a couple of summary plots.

Many thanks for the continuned support from the test beam coords in accomodating our requests and timelines.

H8: Incoming STRAW TRACKER RD (Week 38) (Temur Enik, Katerina Kuznetsova)

  • All three parts (main setup, sMDT tracking and AZALEA telescope) are at H8 and operational
  • Many thanks to Andre Rummler!!
