News from the Facilities Operations Meeting (FOM) (M.R. Jäkel)
Upcoming SPS MDs next weeks :
https://be-dep-ea.web.cern.ch/content/md-planning-north-area
Dedicated SPS MDs - if not anounced differently - are taking place from 8:00 to 18:00
- Previous revious Week 35: Crystal shadowing (beam to TT20 TED) →lost half of the MD
- Week 36: hysteresis compensation MD (no beam to North Area)
- Week 37: Crystal shadowing
- Week 38: No dedicated MD
- Week 39: Slow extraction with transverse noise + TT20 optics (beam to P42)
PS Machine Report (Alex Huschauer)
Very good availability of ~96% since last Thursday, one intervention Tuesday morning
Status of beams:
- ion commissioning well advanced, NOMINAL beams with excellent LEIR-to-PS transmission (fluctuating between 95 and 100%), very good transmission along the cycle; EARLY beams not yet commissioned
- low-energy ion beams for HEARTS run are being set up, 500 MeV ready and sent to EAST dump
- CSBF run started in T8
- took the opportunity to modify T8 cycle according to T9 and TN, meaning it is now BIGTOF-compatible, but parasite will stay at low intensity
Equipment issues:
- KFA71 extraction kicker erratics during the last week, calmed down since expert intervention Tuesday morning
- RF experts added attenuator on longitudinal phase pick-up distribution for AD to improve phase loop signal and hence batch compression
AOB:
- TT2 steering auto-pilot activated (again) on dedicated and parasitic TOF bunches
- FTN RP survey Thursday afternoon after 30h of cool down, showing larger activation towards the end of the line (expected becaue of new optics), but overall reduced activation after the high-flux run
SPS Machine Report (Carlo Zannini)
- Th-Th availability 93.2%
- Operation of SFTPRO beam and AWAKE last week
- Starting ion commissioning
- Commissioning of short cycle
- NA physics also on Wed. in parallel with ion commissioning
Safety (A. Schouten)
General reminder for ISIEC requests.
n_ToF (M.Bacak and P.M.Milazzo)
Higher intensity proton beams were delivered to n_TOF during last three weeks (34-36). At the end, after 30h cooldown, a RP survey has been performed and results have been reported to IPP (no issues) and tomorrow (19.09) will be presented to IEFC.
Data taking on:
- EAR1: LaBr3 detectors for 24Mg(n, n’) and 16O(n, n’) measurements
- EAR2: Array of silicon detectors: 40K(n, lcp) campaign
- NEAR: activation measurements
Protons received
East Area Beam Status (N. Charitonidis)
On call phone number: 67500
T09: Good operation. Beam checked and tuned for HIKE SAC.
T10: Good operation.
T11: Beam check with CLOUD went well yesterday. T11 shutter open until end of run.
East Area Users Tour de Table
T8 Main: IRRAD/CHARM (S. Fiore / F. Ravotti)
Good week. Despite the priority given to T9, also this week POT above the reference intensity for T8 (~2.5e16 p/w, see plot below). The TID generated by the CHARM target was 462 Gy at the reference position.
The centering of the T8 beam, both on the horizontal and vertical plane was, as the back to the usual values >91%.
From yesterday access. In IRRAD, we completed a new batch of samples for LHCb PicoCal and removed the ATLAS ITk FOS sensors setup. Duirng the week we also performed a new batch of nLGAD samples for R&D (DRD3). The EP-ESE (CMS HGCAL samples) and long-term experiments are now stopped for the RP week. In CHARM we removed the setups from SY-EPC, TE-MPE, BE-CEM, in view of the RP week activities. No other users will use CHARM during RP week
The RP week started yesterday afternoon and the HSE-RP collegues will insure the beam coordination (through the usual e-group during this week).
Finally yesterday, togeter with the SY-BI colleagues, we installed the new movable MWPC upstream IRRAD (to be used mainly for the ion MDs, see picture above) and successfully started its commissioning.
T9 Outgoing Main: SHIP (Matei Climescu)
May not be able to attend the meeting, will try to connect remotely.
Many thanks to the PS team for their help and to other areas which allowed us to get more spills, despite many issues arising over the week, the test beam was successful. Clearing of the area was completed around 10AM yesterday without incident.
Points for possible improvement:
- There are two trigger scintillators which are connected with cables of unequal length, this was not made clear to us from the start of the TB and caused issues with our trigger. Equalizing the cable lengths or introducing adequate amounts of delay (or even reading out a single scintillator with 2 PMTs and providing the analogue signals out for coincidence through equal length cables) would be very useful. Otherwise making this clear from the very start of the TB.
- Perhaps some slight improvements in informing us early when the beam will be down, particularly when feeding LHC or otherwise (we were very happy to see BfS using the beam but were informed that we would lose the beam for ~1h 5 minutes early), the beam outage on Tuesday morning was also much longer than expected.
Otherwise we wish to stress how much we are grateful to all of the PS team, particularly to the beam physicists and crane operators who were able to help us out on short notice.
T9 Main: HIKE SAC (Matthew Moulson)
Installed yesterday. Safety check and clearance for beam at 16:00.
Beam tuned and beam files prepared by Dipanwita at 18:30.
Optical pre-alignment system for crystals set up, additional work on data acqusition in progress.
Expect start of program with stable data taking by early afternoon.
Thanks to Dipanwita and all PS personnel for the help with installation.
T9 Incoming Main: NANOCAL (Week 39) (Matthew Moulson)
Installation details same as for HIKE SAC and presented last week. All hardware except calorimeter already installed. Safety clearance obtained with HIKE SAC yesterday.
NanoCal shashlyk prototype expected to arriva at CERN by Monday and will be moved to area outside of T9 for final preparations.
T10 Main: BL4S (Sakura Particles and Mavericks)
Sakura Particles team developed a 2D muon detector to conduct muography.
Mavericks team developed a muon detector for high-altitude balooning application (intensity and energy of muons for different altitudes).
=> Both detectors are based on scintillators, SiPMs, frontend electronics based on the CosmicWatch, and a raspberry pi (Mavericks) or a red pitaya (Sakura Particles).
Here is a picture of the setup in T10 and of our detector.
(Picture taken during low light hours, all used laser tools are rated class I)
- Issues with DAQ system requiring some TLC after change in network topology / environment
- Some issues with broken or not properly plugged in cables
- One PMT failing and needing replacement
- Several NIM modules failed, including at least one coincidence unit after passing testing in our lab, requiring some in-situ replacements and some rather sub-optimal recabling efforts
For the Sakura Particles experiment, the alignment and precise reconstruction of the interaction geometry with their detector is crucial. It took us longer than expected to realise this alignment but we are optimistic that we now have a suitable set of reference coordinates to work within.
For the Mavericks experiment, it is important know the momentum of the detected muons as precisely as possible. Thanks to Maarten et al, we should be able to bracket the momentum to narrow ranges using the XCETs with a view towards improving the statistics regarding the deposited energy. Ongoing effort to estimate parameters (including pressure offset due to finite discriminator threshold and inefficiencies) from pressure scans of mixed hadron beams.
Additional safety check of student detectors specifically finished on Friday, September 13th at around 15:00. Thank you very much to Alex et al for the flexiblity and understanding and for the feedback!
First successful data taking night of Tuesday to Wednesday, we hope our second week will be more successful and will allow us to complete all planned measurements.
Thank you so much to everyone who is involved in BL4S as data analysis supporter, beamline physicist, beam instrumentation, safety, and so much more! We are really grateful to everyone involved that we can be here to test and calibrate our detectors and for all the help and support.

H4:
Outgoing Main: NP04 (Christos Touramanis)
Please accept our apologies for not attening the meeting today. Both myself and Filippo Resnati are in the USA this week.
The NP04 beam run was compelted succesfully with smooth data taking until Monday morning as had been agreed here to allow for GIF++ preparations.
We are now continuing with a few weeks of detector tests and development.
We thank the coordinator, our BE physicists (Nikos, Bastien, Inaki) and the operators in the CCC for their support underpining our very smooth and efficient run over pretty much the whole summer.
Main: DRD1 (Yorgos Tsipolitis, Karl Floethner, K. Kuznetsova)
Most setups finished installation and some started taking first data - huge profit from the extra day.
No Problems with safety.
Short magnet test planned at 16:30 today (Thanks for Bastien for availability).
We agreed on a three access scheme with GIF++ (usual times: 09:00 ~1h & 15:00 ~30min-45min & 22:00 ~1h).
Muon Beam has been adjusted to deliver maximum rate (~60k-70k per Spill) for DRD1 while GIF++ has no restriction in access (PAXNA14404 crutial - thanks to Nikos!).

H6:
Outgoing Main: ATLAS BCM PRIME (Ignacio Asensi)
Apologies for missing the meeting. During this week with had many problems with our setup due to configuration issues. It was quite difficult to take meaningful data. During Tuesday we were able to get everything in place so we started taking meaningful data. We asked the MALTA people if we could stay for a few more days in the Telescope, which they kindly agreed. Our setup can be removed in 20 minutes, so it will be removed when any short access is planned by the primary users or they are OK with it. Safety inspector has been notified and he agrees with the installation.
Main: ATLAS HGTD (Stefano Manzoni)
First of all I want to apologize for skipping the meeting.
Data taking is in progress steadily. The beam has been reoptimize to fit also PICSEL size preferences. Not many accesses are expected in the next days on our sids, probably 2h access every two days should be enough.
We want to thank BCM Prime/Malta team for the nice interaction we had last week.
Parallel: PICSEL (Mathieu Goffe)
Setup installed yesterday and first data took without any problem, Beam size was adujsted to be a bit wider. Data taking in progress.
Incoming Main: EP PIXEL (Week 39) (Younes Otarid)
Characterzation of H2M thinned samples (19um, 16.3um)
Telescope setup already installed and commissioned

H8:
Ongoing Main: DRD6 IDEA DRC (Please Put Your Name Here)
Outgoing Parallel: BI XBPF (Inaki Ortega)
Our parasitic beam time was successful thanks to the generosity of the DRD6 IDEA colleagues, who provided us with several hours of beam time to advance our program. We’ll continue and complete it in week 41, when we’ll be the main users.
We would like to keep one of our detectors, the new XBPF beam profile monitor, installed in place of the FISC.042.476, at least until week 41.
