Safety / Radiation Protection (Laura Rowland
- Experimental areas and their control rooms are RP Controlled Areas - Please no food (or storing of food) in these areas.
- Online ISIEC forms allow the granting of a three week safety clearance. If you plan to stay longer / extend your beamtime / make any modifications to your setup please contact the EP Safety Office to amend your clearance.
n_TOF (Nikolas Patronis)
EAR1: The second part of 243Am(n,f) measurement which is focusing on the higher neutron energies is going to start. For this measurement the 28ns longitudinal width is important to be preserved. 1 month long measurement. Today we have still to work on the setup for this measurement (beam-line modifications, supports, electronics optimization)
EAR2: 30Si(n,g) measurement is ending successfully. 64Ni(n,g) is about to start. This measurement will stay three weeks.
NEAR: In the activation area (a-NEAR) the repair of the moving table was successfully accomplished yesterday. Next week the diamond detector will be mounted as to test different electronics configuration. Irradiation hardness material studies are on-going in i-NEAR.
PoT: 1.10E19; Better than expected! Many thanks to the PS teams!
East Area Beam Status (M. Van Dijk)
T09: Continuing with low momentum configuration. No issues.
T10: Good operation. Yesterday installation of helium for low-pressure XCET for BL4S, to be tested today.
T11: No user just now.
East Area Users Tour de Table
T8: IRRAD / CHARM (F. Ravotti)
Good week, no issue with operation. Cumulative intensity delivered to T8 better than previous week (approching ~2E16 p/w, see plot below). Beam alignment on both X- and Y-axis OK (again >90% for X-axis) but less good that beginning of the year (~98% until week 22) - beam center has the tendency to slowly drift on X direction (see plot below where the red curve show the beam center intensity).
During the access on Wednesday, we exchanged dosimetry samples and all long-term users continue EP-ESE, TE-MSC [including N2 experiment], CMS Pixel [scanning table], RD50, etc. Installed 2 ATLAS experiments for HGTD and ITk Pixel [scanning table] (IRRAD). CMS DT and BE-CEM continue testing, ATLAS (DCT card) completed (CHARM).
Upcoming access, next week.
T9: WCTE (Akira Konaka)
Smooth data taking and some online results shows good pions to muon separation in the sub-GeV range. We will continue taking comprehensive data to study particle identification and each particle flux in sub-GeV range.
The magnet was finally shipped last Friday and will arrive in Geneva tonight. We develop a plan to install the magnet on Wednesday next week for the tagged photon beam study.
T10 Outgoing Main: ALICE ITS3 (Paolo Martinengo)
Smooth data taking, thank you very much for the 3 spills during the last evening/night, they were instrumental to complete measurement
T10 Outgoing Parallel: ALICE TIMING (Please Add Your Name Here)
T10 Main: BL4S (Margherita Boselli, Sarah Zoechling)
Experiment set up yesterday (scheme presented last week).
Many thanks to Abou and his colleagues, to the gas team, and to Inaki and his BI colleagues for their help!
Safety check took place this morning.
Beam hopefully today.
Aim is to calibrate the detectors, align the set up, and take some preliminary data.
T10 Incoming: RE21 CBM - Week 30 (Please Add Your Name Here)
Outgoing: HiRadMat (P. Simon)
MD + small experiment week.
Experimental program 95% done, waiting for wirescanner MD in SPS to extract higher intensities on Friday. MD on transferline optics and BTVs.
North Area Beam Status
H2, H4, H6, and H8 Beams (M. Van Dijk)
H2: Fault in trim that was resolved.
H4/H6/H8: Normal operation.
Other Beams P42, K12, and M2 (M. Van Dijk)
M2: First checks of the beam done with NA64mu. Three upstream profile monitors do not work. Local electronics to be replaced. Access is being planned.
P42/K12: All prepared for going to the NA62 beam dump run that will start today at 12:00. Yesterday after the intensity increase and going to the 40 mm long target at T4, we checked the correct transmission towards T10, aiming at running at about 55 - 57 units for the next 10 days. For last night, intensity on T10 was decreased by closing the P42 TAX to avoid too many changes in the machines and to the other users in H6 and H8.
North Area Users Tour de Table

- potentially we might test a new H2M technology demostrator
- Apart from this we hope to:
- finish our commissioning of MCP-PMT and CFD readout chain for an improved digital timestamp recording
- commission a cooling setup of our telescope and detectors with proper monitoring of air flow, pressures and temperatures and compare the performance with and without
H6 Incoming Parallel: ALICE ITS3 - Week 30 (Paolo Martinengo)
Plan to install as scheduled
H8
H8 Outgoing Main: ATLAS TILECAL (Tigran Mkrtchyan & Giulio Usai)
A few slides are attached on the indico agenda. Executive summary is described here:
- Collected complete data with all beam types
21.6M hadrons
3.9M positrons
3.6M muons
2.7M positrons + 1.8M muons for MAPMT studies - Ranging from low 10GeV energies up to 180 GeV
- Huge improvement in delivered positrons (Thank you!)
- Cleaner hadron beams with lower electron contamination
- Cherenkov response still unclear, we will analyse the data and report back
- All collected data to be processed in the next weeks for more detailed analysis
We would like to thank everyone at the SPS and the North Area.
H8 Main: MGTD TRD (Julia Velkovska and Yulia Furletova)
Our team of 7 people arrived and when through all trinings necessary to operate the beam teast.
We have our prototype detectors delivered. The ArCO2 and N2 gasses were delevered by CERN, and we have secured XeCO2 in collaboration with colleagues from ATLAS-TRT.
Unfortunately, our shipment of readout electronics was delayed to a point where we will not be able to receive it before the end of the test-beam time. We are renting electonics from the CERN electronics pool and buying/borrowing cables and other equipment to improvise a DAQ system.
The box with the support structure for the prototypes arrived at CERN yesterday. We are in the process of retrieving it. The assembly of the setup will follow today/tomorrow.
We re-scheduled our safety inspection for Friday, July 21st at 4 pm.
We discussed the beam parameters with Maarten Van Dijk. He is working on providing the trigger and Cherenkov detectors for PID.
We thank the CERN team for their help and flexibility with our changing schedule.
H8 Incoming Main: POKER (Andrea Celentano)
Goal of the measurement: characterization of the POKERINO calorimeter (3x3 matrix of PbWO4
crystals with SiPM readout) with electrons, at different energies and intensities.
- POKERINO detector already at CERN. Shipping of remaining equiment (DAQ system, mechanics) on July 25th. Total weight and volume very limited, will be handled by hands by the team (no crane support requested)
- Team members will arrive at CERN July 25th. All CERN accounts already setup, all safety courses already taken.
- Technical meeting with Michael Lazzaroni, Maarten Van Dijk, and Silvia Schuh-Erhard on June 27th to define experiment needs in terms of infrastructure (tables, beamline detectors, cables, patch-panels).
