Safety (James Devine)
This week we have seen large numbers of:
1)People without helmets and safety shoes
2)People in shorts
This is great in Restaurant 1, but not in your experimental area.
You are reminded: A personal dosimeter, helmet and safety shoes are mandatory* in EHN1, 157.
*It is permitted to store your helmet and shoes in your counting room, however you must go straight there to retrive them upon entering the building. The dosimeter is mandatory at all times.
It is mandatory (HSE memo) to wear long trousers in all areas where safety shoes are required, i.e. all experiment halls and beam line areas.
nToF (M.Bacak and P.M.Milazzo)
Smoth data taking in all experimental areas.
EAR1: last days of the r(En, g) campaign
EAR2: test of a diamond detector
NEAR: activation measurements
From 12.07 new campaign will start:
EAR1: Cu(n, g)
EAR2: test of feasibility of the challenging Ar(n, g) study (a dedicated container in aluminium and carbon fibre has been realized and tested at high pressures)
Technical drawings and real target container.

East Area Users Tour de Table
T8 Main: IRRAD/CHARM (F. Ravotti)
Very good week. Cumulated 2.9E16 p/w and a TID of 400 Gy as required by the current users in the CHARM area.
After three weeks where the beam was affected by larger “drifts” than usual (more often and with larger magnitude) the statistics of this week are back to the expected values we had until w23 (~95-96% of spills are centered on both axis, now in w27). Moreover, also the “slow” intensity drift basically disappeared this week (see plot below to be compared with the one in last week report).
During the access on Wednesday: (1) In CHARM we exchanged cards and components for BE-CEM, removed the SY-EPC setup and installed one for CMS-RPC. (2) In IRRAD we excahnged polymers/resin samples for TE-MSC, while the CMS MTD ETL and all other long-term experiments continue.
We continue until next Wednesday with the extracted standard high-intensity (8oE10 pps).
T9 Outgoing Main: CALICE/DRD6 (Yong Liu)
- Smooth data taking: crystal calorimeter prototype
- Muons: 5 GeV; electrons: 1 – 10 GeV; pions 1-10 GeV
- Electron data: with varying beam collimator slits to study impacts from beam momentum spreads
- A new SiPM-readout electronics chip (32-ch)
- Timing studies with crystal-SiPM units
- Crystal bars with different lengths
- Several combinations of SiPM and preamp types
- Oscilloscopes: 5 GS/s and 16 GS/s
- Summary: a successful beamtest for CALICE/DRD6
- Collected decent statistics of data samples
- Enabling EM and hadronic shower studies, and timing performance studies
- Dismantling and wrap-up completed in July 10 morning
- A big Thank-You for all the great support received
T9 Main: MPGDCAL (Luigi Longo)
Gained half day wrt the schedule thanks to all the help we received in moving from SPS to PS all our equipments.
Setup is in place and the safety inspection just happened →→ everything fine
We are going to set up the beam and start our measurements
T10 Outgoing Main: ALICE TIMING (Manuel Colocci)
- Took data successfully (CMOS-LGADs, LGADs and SiPMs), out of the zone on Wed at 10.00
T10 Main: IDEA CC (Please Put Your Name Here)
North Area Beam Status (L. Nevay)
Standby phone number: 67500
Proposed proton sharing with T4 wobbling at -120 GeV/c in H6, -300 GeV/c in H8, and 500 mm T4 target head:
| T2 | T4 | T10 | T6 |
|---|---|---|---|
| 30 | 20 | ≈1≈1 | 30 |
From next week, Wed, 17.07.24, with standard T4 wobbling (120 GeV/c in H6, 180 GeV/c in H8) and 180 mm T4 target head:
| T2 | T4 | T10 | T6 |
|---|---|---|---|
| 30 | 42 | 21 | 30 |
General: Reduced number of protons on T4 but with a longer target to provide low intensity run for NA62. Despite the lower number of protons, the e- beams for H6 and H8 will be better and the overall intensity to H6/H8 does not change.
H2: Beamline limited to 150 GeV/c. NA61 beam tuning ongoing, CEDAR issues solved by SY/BI. “Moving beam” issue present, corellated with H8 beam file loading.
H4: Smooth operation. Still issues with the NP04 HP XCET, a device will be borrowed from T10 and installed today.
H6: Good operation. First e- beams of the year with good rate and purity.
H8: Good operation, no issues. Request to do optics measurements for a couple of hours, most probably easiest on Friday.
P42/K12: Prepared low intensity for NA62.
M2: Issue with pressure sensor for CEDAR02 in M2 from last Thursday, solved on Saturday morning. Other than that, good operation. Test with high intensity planned on July 19th, 08-12, with 150 units on T6 during this time.
Outgoing HiRadMat (N. Charitonidis)
Very smooth data taking, thanks a lot to all the injectors and the coordinators / operator crews!
AWAKE (M. Bergamaschi)
| M | T | W | |
|---|---|---|---|
| SPS extractions to AWAKE | 140 | 234 | Electron beam |
| Hours of beam to AWAKE | 1.3 | 2.2 | Electron beam |
Detailed program:
- Monday: issue with e-beam modulator required morning access, afternoon check of proton bunch parameters and protons diagnostics
- Tuesday: start of plasma studies, interupted by problem of plasma source the required an access
- Wednesday: problem with access system (cable veto faulty) that required access in the morning, afternoon dedicated to e-beam studies
North Area Users Tour de Table
P42-K12:
Main: NA62 (Michal Zamkovsky)
We would like to thank for the setup of the low intensity beam for NA62.
We had a problem with the power cut on Monday and cancelled the night shift.
We closed the access and notified CCC that experiment will be without shifters.
Then we found that during the night we had beam on T10.
We benefited from the down-time and BE-EA team fixed the problematic electrovalve in sector 1 of K12.
We noticed the parallel MDs (Ship MD) during every day - will it be like that for the whole week?
M2:
Main: AMBER (Thomas Poschl, Josef Novy)
-
data taking with Deuterium target ongoing
-
last week(end) very productive beam delivery
-
last Friday evening/night issue with Cedar2 pressure sensor readout -> not able to set pressure until a remotel power cycle saturday morning (around 9h of data without Cedar 2)
-
since Monday during the day issues with beam quality (varying intensity, changing count rates on veto detectors/ changes of halo, empty spills, 50Hz noise, inhomogenous intensity in spill)(took additional spills to compensate for potential problematic runs)
-
finished 160 GeV/c, 80 GeV/c
-
currently switching to 250 GeV/c
-
back in schedule to perform systematic studies (Cedar studies, Empty-target studies) at the end of beam time (end of beam, Wednesday 08:00)
Incoming Main: NA64mu (Week 29) (Vladimir Poliakov)
NA64 setup
The installation of all equipment will start July 18 after dismounting of CEDARs in M2 tunnel.
The high intensity muon beam test will be Friday morning, July 19. The two hadron calorimeters and large Straw detectors will installed at Friday afternoon.
The installation and commissioning all NA64 detectors until Friday July 26, when will be safety visit.
H2:
Main: NA61 SHINE (P. Podlaski, B. Maksiak)
- Some issues on the way:
- Power glitch: all our equipment went OFF on Tuesday (9.07) morning, similarily as in AUL trigger, but no AUL was pressed!. EN-EL suspects glitch on 48V supply line
- Problem with one of the DWCs borrowed from CMS
- The efficiency was dropping significantly over time, we observed it during the weekend
- Inaki tried to remotely increase HV but it helped only short-term
- Strange noise was observed on the timing outputs
- BE-BI discovered that there was no gas flowing, HV interlock did not work
- Chamber was replaced on Monday, gas flow restored, since then works nicely
- Jumping beam is back. This time we correlated it with H8
- CEDAR alignment and timing issues, solved yesterday by Inaki
- Setup was finished yesterday, over the night we took pilot physics data
- Proper physics running will start today afternoon
H4:
Outgoing Main: DRD1 (Karl Jonathan Floethner)
Beam
Good Muon Beam Purity (as in April - no showers produced by hadrons in our
detectors)
Pion Beam: >10e+7/spill (good for the tiggered tests with VMM3a)
Rate (both muons/pions): Very Satisfied. Huge thanks to Nikos and Frederic (Aberle, RP) for
helping optimize beam intensity and RP alarms in April. DAQ rate doubled in some setup. Very
important and really appreciated.
Setups
All 8 groups being able to take useful data and majority to complete the planned tests
(PICOSEC mm, PICOSEC uRWELL, MINICACTUS, STRAW, GDD/DRD1 Tracker, cylindrical μGroove USTC, MPGDHCAL, FCCmuons).
See attached slides for more information.
Sharing with GIF
Everything going smoothly on our side (only problem was from time to time disabled phone in control room). 3 access scheme as base works very good. Thanks for accepting additional unforeseen accesses. The shared end-of-the-beam-bbq was excellent as always.
De-Installation
Very fast this time (all setups have been ready to move out before 10am).
Next test beam in September/October. Part of the equipment left in the area and in the storage
close to H4 (very helpful to minimize crane use and facilitate our next installation).
Thanks to everybody for the support
Outgoing Parallel: GIF++ (Paolo Martinengo)
Data taking successfully ended, all users happy
Reconfigured for beam pipe in the bunker, some delay due to
issue with isobutane line (electrovalve)
Main: NP04 (Christos Touramanis)
Firstly, apologies for beig double-booked and not able to attend today. Here is our summary:
Since our beam two weeks ago we optimised our DAQ and now we can take data at 40 Hz (previously 25).
We received first beam yesterday at around 16:30 and took data at 7 GeV until this morning.
Main concern is the beamline Cherenkov (the High Pressure one) which was not working since we started this year.
Further studies (thank you Inaki) concluded yesterday that the light/optics is the problem, everything else was checked and works.
Today we exepect an exchange with another Cherenkov from the East Area (Nikos coordinating, thank you).
By the end of today we aim to start our physics data-taking with pions at 1 GeV, changing sign every couple of days to have a balanced data set in case of beam delivery problems.
Reconstructed events from our first week of beam were shown already by the CERN Director for Research and Computing at the ECFA meeting last week, and also on various media.
H6:
Outgoing Main: POKER (Andrea Celentano)
Very productive beam time!
- Installation and the safety inspection done on Wednsday, July 3th
- Trigger and DAQ commissioning on Thursday, July 4th
- Friday and weekend main task: Micromegas commissioning (saturday afternoon a gas leakage was found in the gas line connecting the gas bootle from the outside storage area to the EHN1/R-K52 - very good support from gas team who helped us to solve the issue)
- Monday and Tuesday: data taking with e- beam, from 10 GeV/c to 100 GeV/c at 10 GeV/c steps. Momentum collimators closed to ± 0.5 mm to minimize momentum spread. Excellent beam intrinsic momentum spread.
** See below for the energy distribution collected with 80 GeV e- beam (no leakage correction neither SiPM saturation effect corrected for). - Tuesday: intensity scan with mixed 120 GeV/c - maximum value was 4E6 particles/spill – we triggered radiation alarm.
Main: MUONE ECAL (Fred Gray)
Installation is essentially complete, and we received our safety clearance just before this meeting. We are continuing to diagnose a few unstable APD channels and complete a few remaining tasks to prepare the detectors. We expect to close the area and start collecting beam data starting in the early afternoon today.
Many thanks to Inaki et al. for splitting the signal from the trigger scintillator, to Laurie for preparing beam files and providing training yesterday, to Alex for safety advice, and to the crane staff for installing an iron block for our muon veto.
Incoming Main: DRD6 MAXICC (Week 29) (Marco Lucchini)
Setup is ready for installation on Wednesday 17th.
Requested safety inspection at 17h00 and patrol training.
Will NOT need a crane for transport material
Will need a DWC, a DESY table and a rack to house a VME and a NIM crate as in the original request.
Setup will be housed in a 60x60x60 cm box located on the DESY table and cooled with chiller.
Beam requirements:
- beam size: <1cm rms
- mostly 20 GeV electron beam
- few runs with higher electron energy (50-150 GeV) if available
- few run with pions/muons (any energy is OK)
H8:
Outgoing Main: FASER NU (Akitaka Ariga)
Goal:
- Detector performance tests: efficiency, stability
- Momentum calibration of FASERnu detector (50,100,200,300 mu-)
- Hadron id/mom/teraction studies (50,100,200,300 hadrons-)
- FASERnu upgread prototype test
History
- Wed (3rd July)-Thu, Beam tuning
- Thu, test emulsion detector irradiation
- Friday-Wed yesterday, irradiation
- Irradiation is completed Wed night
- Thu today, we will clean up the zone
- Next days, chemical processing of emulsion films in Meyrin
No major issues on beam. Great!
A couple of time, magnets lost current (500A -> 20A in most of magnets). Solved by CCC.
A slight delay due to a user-side issue of irradiation procedure.
We thank very much Martin, Barbara, Michail, Maarten, Johannes for everything, in particular for an additional day of beam time.

Main: MPGD TRD (Yulia Furletova)
Our shipment with equipment has been arrived few days ago. Starting to assemble. After discussions with ATLAS-TRT team - requesting to shift our setup to PPE158 ( control room (887-R-Q60))- we are planning to use the same beam and Cherenkov det settings,and will relay on the ATLAS-TRT calorimeter and trigger setups.
On the Cherenkov detector- we will need an analog signal in the zone ( we are going to read it out with our fADC system).
Requesting to move our Ar/CO2 gas to the PPE158 as well. Planning to have a safety check on Wed.
Beam setup: electron beam 10-20 GeV, pion beam
