Availabilities (Thu-Thu)

Issues:

Safety (J. Devine)

Thank you for following the HSE guidance on shorts! We haven’t found anyone recently in shorts in the beamline zones, which is very good.
Also thank you for updating us as to any delays with your setups, this is very helpful and has worked well this week.
General notice: are you going to be working with magnetic fields? If so please consider the following training courses:
Magnetic Field Awareness - online. This is an online course, very easy to complete and covers the basics of working safely with a magnetic field. This is the minimum for test beam teams working with magnetic fields as part of their experiment.
Magnetic Fields - classroom session. This is an excellent in person course covering the technical and safety aspects of working in a magnetic field. There are only a few sessions per year, so add yourself to the waitlist now if you plan to work with strong magnetic fields in the future. The Magnetic Field Awareness course is a pre-requisite.

nToF (Michael BACAK and Paolo M MILAZZO)

Smooth data taking in all experimental areas.

A large amount of work has been done by the PS staff on TOF beams to provide more protons for the incoming run on the 88Zr radioactive sample.

EAR1: 63Cu(n, g) measurement has been completed and the 238(n, g) campaign has started, no changes needed in the experimental set-up.
EAR2: Auxiliary measurements for the 88Zr(n. g) campaign have been performed; today the sample is arriving from PSI and will be directly put on beam.

NEAR: Activation measurements


Protons received in standard conditions

East Area Beam Status (B. Rae)

On call number: 67500

CESAR-LSA deployment for T10 and T08 planned for Week 35, August 28th.

T09: Good operation. WCTE assembly also progressing well on schedule.
T10: Good operation.
T11: Quite a few issues with a new version of CESAR deployed for T11. Beam files could not be loaded or saved. Problems were caused by using a mix of CESAR versions as well as some unexpected problems with the login via location that were not seen during the testing phase. About 2 hours of interruption during start of P349. After this, good operation.

East Area Users Tour de Table

T8 Main: IRRAD/CHARM (F. Ravotti)

Again very good week in T8, protons reached ~2.8E16 as in the previous weeks and TID in CHARM reached specification level (500 Gy).

T8 transmission very good and beam alignmet (% of spills within +/- 2mm from the center) above 96-97% on both axis.

In IRRAD we are continuing with long-term experiments only (TE-MSC, EN-MME, etc.) - no user/samples exchange yesterday.

In CHARM, yesterday the ATLAS setup was removed, new user in the rack installed (SY-RF) for long term exposure. CMS and BE-CEM-EPR setup continue.

T9 Outgoing Main: STCF ECAL&PID (Yunlong Zhang)

Firstly, thank all the CERN help. expecially, Dipanwita, Aboubakr, Alex, Anastazja…

In the past two weeks, we have collected about 30,000,000 events.
Muons, which were uesde to calibrate dtetectors, about 3.5 M events.
Positron, were used to calibrate crystal calorimeter, about 15 M events.
pions/Protons, were used to test PID detector, about 13 M events.

pure CsI calorimeter, 1 GeV positron, the energy resolution is about 2.5%, very good! The T9 beam momentum resolution is excelent.

PID detetcor, 3 GeV/c pion/proton mix beam

The detectors were parcked. The detailed analysis will be conducted later.

T9 Main: NP06 ENUBET (Andrea Longhin)

Transportation, handling, logistics: a big thank you to the logistics team for help with the installation and for having the detector quickly transferred from Prevessins yesterday despite some flaws in the original EDH request.

Installation: The detector installation is almost finalized. We plan to complete it this morning. Safety visit is planned for today @ 16.00

Setup is similar to last year but with:

Plans: Run with mixed beam (hadrons, muons, electrons) and “pure” electrons settings. No change wrt last year. We can use the same magnet configurations. Test uniformity, energy resolution, particle identification, effect of beam tilt.

Final remark: it is quite hard to work in T9 due to the high temperature (~30 oC) and humidity (helmets, long trousers), maybe it is exceptional but is there any possibility to improve this ?

T10 Outgoing Main: EIC BARREL ECAL (Jeongsu Bok)

T10 Main: ALICE TOF (Yongwook Baek)

T10 Incoming Main: ALICE ITS3 (Week 34) (Paolo Martinengo)

(Almost) Ready to take the beam, DESY 4 needed

Target intensities

T2 T4 T10 T6 Date/Comment
30 100 55 30 original plan as of last week
30 85 45 30 adapted due to higher radiation last Friday
50 85 45 30 further adaption yesterday to reduce beam size in P42
30 54 21 30 planned from Monday 12.08.

H2: Smooth operation.
H4: Smooth operation.
H6: Generally good operation. Quad 426 tripped a few times but comes back quickly. We’re monitoring it but there is no obvious fault.
H8: Mostly good operation, some magnet trips over the weekend likely due to heat. Access matrix changed to add PPE168 to PPE158 for the next weeks, until XTDV.042.572 can be repaired (27-28 August). Many thanks to DRD6 IDEA DRC for allowing time for this.
M2: The 2nd MBPL for NA64mu had some cooling issue and is currently limited to 740 A as opposed to 800 A. Different energy hadron files and the 160 GeV/c muon file have been checked.
P42/K12: Elevated dose rates observed at the bridge towards TCC8/ECN3 led to a decrease of the P42 intensity (and with it T4) last Friday. Due to the sharing, the beam size in P42 was vertically larger than it used to be. After discussions with HSE-RP, we proposed to increase the intensity on T2, thus reducing the beam size in P42. Since yesterday, radiation levels are ok for the current intensity. We had a few interlocks due to Bend 2 of K12, so we changed the tolerance in p0survey slightly and the experts will have a look on the power supply.

Our test beam has been running fairly smoothly since last Friday, except for some problems with a quadrupole failing two or three times in H6 (thank you to Laurie for quickly help us with it)

Yesterday we changed the DUT and started testing our latest version of ASIC (ALTIROCA) for the first time.We will keep testing it for a few more days and then move on to irradiated samples.

Incoming Main: ATLAS ITK PIXEL (Please Put Your Name Here)

H8:

Outgoing Main: QFIB (Suat Ozkorucuklu)

We are pleased to report that our recent test beam for QFib at the SPS was highly successful. We extend our sincere gratitude to all involved parties, including Eva Barbara Holzer, Maarten Van Dijk, Martin Schwinzerl, and Lazic Dragoslav for their dedication and hard work.

During the test beam, we collected valuable data using various particle types and energies:

In addition to these measurements, we tested a new prototype detector (PSQ), which featured different Quartz radiators, a mirror, and a Microchannel Plate (MCP). This allowed us to gather critical data on the performance of these components under experimental conditions.

Throughout the test period, we conducted a total of 10 scans (each lasting approximately 8 hours), and performed over 25 calorimetric runs. These efforts have significantly contributed to our understanding and development of the QFib and PSQ detectors.

Moreover, this test beam provided an excellent opportunity for educational engagement. We had the pleasure of having two bachelor students and one master student on board, who gained invaluable hands-on experience and contributed to the success of the project.

Once again, thank you to everyone involved for their exceptional work and commitment. The insights and data obtained from this test beam will undoubtedly propel our research and development efforts forward.

Main: DRD6 IDEA DRC (Seungkyu Ha)

We have installed our calorimeter modules on the sapphire table. We also installed the DAQ system. Beam pipe also installed yesterday.!

We requested an electron hadrons muons beam, and Maarten proivded beam profile files last night. Thank you Maarten!

Patrol training was done and we have requested a safety check, which will be done today (we are updating our configurations, 2PM)

After safety check, we will start our test beam programs!
