You should use dedicated grounding cables instead - Please complete your [ISIEC submission](https://ep-th-safety.web.cern.ch/isiec-safety-clearance/) with all hazards at least one week in advance. A dedicated time slot for safety inspections is reserved for Wednesday afternoons (15:00-17:00). - Obligatory to **wear the PPE** as defined in the [safety video](https://indico.cern.ch/event/1645142/contributions/6916288/subcontributions/598017/attachments/3211079/5739980/2026_GeneralSafetyVideo_EA+NA.mp4) that was shared during the beamline user meeting and at the end of the ISIEC. Note that failure to do so is considered a professional fault ([EDMS 3413229](https://edms.cern.ch/document/3413229/LAST_RELEASED)). - **Food and drinks are not allowed** in radiologically classified areas. Use the dedicated coffee room outside the classified area instead (887/1-A92). - For **fluorinated gases** that are not supplied by the gas services, please check the [HSE website](https://hse.cern/f-gas/temporary-experiments). Bringing your own gas to CERN is no longer permitted by HSE! HSE are also requesting you fill out the form a minimum of 3 months before your experiment slot - this might not be possible given the physics schedule for this year, but please give them as much notice as possible and don't hesitate to ask us in EP safety for help or confirmation if you have any initial questions. - For special requirements (e.g. **flammable gases**, lasers, bringing your own lifting table, etc.) contact us as soon as possible. ## TT2A Main: n_TOF (Alice Manna, Paolo M Milazzo) Smooth data taking after LINAC4 restart - EAR1: Study of the 235U(n, f) cross section with Parallel Plate Avalanche Counters and a plastic scintillator wall - EAR2: Set-up of 27 C6D6 liquid scintillators to study the 239Pu(n, g) reaction - NEAR: Activation measurement on a 94Nb sample   ## East Area Beam Status (B. Rae) On call phone number: :phone: [67500](tel:+41227667500) T9/T10: Good operation. T11: No user. ## East Area Users Tour de Table ### T8 Main/Parallel: IRRAD/CHARM (S. Fiore / F. Ravotti) Besides recovering from the LINAC4 issue - protons were back to T8 on Thursday ~15h30 - the intensity delivered to T8 was lower than usual because of the parallel CSBF run that required few additional short access slots during the week (total POT ~1.9E16 p/w, see below).  Beam centering statistics also not particulary good this week. Only about 80% of the spills on the horizontal axis were +/- 2mm from the center of the trajectory (see below). The proton cooldown on Wednesday night (3-8am) was used to continue the preparation of the ion beams for the HEARTS run.  During the access on Wednesday in IRRAD we removed samples from DRD3 (LGADs) and TE-MSC as well as the EN-EL experiment and we installed CMS ECAL and SiC-LGAD samples batches (DRD3 WG6). The rest installed last week, together with the sample batches alredy in the facility, continue irradiation. Moreover part of the HEARTS setup has been installed upstream IRRAD to host the MWPC and thus continue the work during the overight ion-MD slots. In CHARM a new setup for CMS HCAL, hosted in an additional rack at the connection point has been installed, LHCb for FastRICH FEE and SY-BI for BeamCam cameras continue testing. Usual change of components for EPR section R2E qualification activities. Then the run will last until Wednesday morning with few hours to be used again for ion MD until 8am. RP Week 2026 at CSBF has officially finished on 10/06. All the experiments planned were successfully completed, with a few modifications in the planning due to the issues with LINAC4 last week. Many thanks on behalf of the CSBF team 2026 (picture @ meeting point after short evacuation on Tue 09/06 10:00 am due to gaz alarm in 157)     ### T9 Outgoing Main: IDEA CC (Please insert your name) ### T9 Main: BL4S (Berare Gokturk, Seyma Esen, Markus Joos)  We will be doing pi0 creation and reconstruction experiment. To create the pi0's we will be using Tungsten and Carbon Fibers, to detection of gammas we will be using lead-glass calorimeters (We have 17 of them, we will create matrix of 4x4.) We have installed two finger scintillators, two DWCs, our target, and the lead-glass calorimeters. We will be using the Cherenkov detectors and Scintillators that belong to zone. The DWC's are on XSCA table and the lead-glass calorimeters are on the DESY table. Currently cabelling and labelling is finished, we have the safety check at 11:30. And hopefully today we will start with the calibration of the calorimeters. ### T9 Incoming Main: ALICE RICH (Roberta Pillera, Nicola Mazziotta) The planned set-up includes a Desy, and 1 (if possible 2) XSCA tables. The RICH prototype is located in the middle of the setup on the Desy table. Upstream/Downstream two tables with fiber trackers will be installed for beam particle triggering and tracking. We will start installing as soon as the area is clear. We will install the detectors ourselves, infrastructure team support needed only for Desy and XSCA table(s) installation.  The RICH vessel will be flushed with CO2 cooled down up to -40°C. Adequate spill containment and spill response material is foreseen. The ISIEC form is already submitted (id 179) requesting the safety inspection on 17 June at 16:45. We will use CO2, argon and nitrogen gas. We plan to use the beam files already used in the previous runs (Dec 2025 and May 2026). As for the other times we will need the analog signals of the XCETs and beam scintillators. ### T10 Outgoing Main: ALICE TIMING (B. Sabiu, M. Colocci) Both setups, one with CMOS-LGAD prototypes and one with AC-LGADs, took good data in the second week.   ### T10 Main: EIC ePIC pfRICH (Alexander Kiselev) * Since last Thursday, disassembled at H8 and moved from SPS to PS * The setup is mostly re-installed at T10, except for signal cabling, etc * Safety inspection booked for 15:00 today ### T10 Parallel: EIC DRICH (Please insert your name) ## ΤΤ66 HiRadMat (P. Alexaki) * FIREBALL-IV beam time ongoing (when LHC allows). * Some issues with the equipment require access today. * Program scheduled to finish on Sunday (14.06) ## North Area Beam Status (B. Rae) On call phone number: :phone: [67500](tel:+41227667500) **H2/H4**: Good operation. Wobbling change planned today to high-purity electron preference to H2. **H6**: Good operation. **H8**: Good operation. **M2**: Good operation. **P42/K12**: The MNP33 power converters had a problem restarting after the LINAC stop, but this was fixed promptly. ## North Area Users Tour de Table ### H2 Main: CMS HGCAL (A. Steen) This we focused on prepare our detector configuration/calibration with a mix of internal calibration runs and runs with beam to validate the calibration.  The configurations are now ready for electron beam energy scans. We plan to acquire electron data with energy between 20 and 300 GeV. We also made progress on our self trigger procedure which we hope (as a bonus) to validate this week. ### H2 Incoming Main: DRD6 SIW ECAL (V. Boudry) - Preparation: - all 15 boards produced, commissioning (electronics, 90Sr) almost complete - Data space ready (DRD Calo EOS + IJCLab + LLR spaces) - DAQ and Online reconstruction ready - Simulations for tuning the program almost ready - installtion: no hasard, small set-up; a simple table on the NIHKEF plateform will do. - Running: mostly high purity e± beam typically: - (10); 20; 34; 52; 74; 99; 128; 160 GeV + large μ beam (1 day) + 10-30 π's (at the end) - Admin: a big THANK YOU for the new testbeam page, not yet perfect but immensely useful. ### H4 Main: CMS ECAL (M.Campana, G. Lavizzari) - Commissioned alignement & delays for hodoscope and MCP - Beam tuning comleted - Energy scan in one crystal completed with nominal ASIC settings - Scan at high energy between two cristals - Should HGCAL complete the scan and can spare some time, would it be possible to change priority again? ### H4 Incoming Main: LHCB_ECAL (L.Martinazzoli / E.Caire) TB Goals : * Preparation for the TDR * Test of different DAQ including a timing ASIC to be tested for the first time at high energies Infrastructure request: * 1 DESY table for the test box * 1 XSCA table Beam request : * high purity electrons 20-100 GeV/c (95% of the time) * hadrons at some energies matching electrons (small fraction of time) * muons for alignment & debugging We will need to crane equipment in the area. We would request a basket, or pallet with metal fences in the morning. ### H6 Outgoing Main: ALADDIN (I. Panichi / F. Bucci) - ALADDIN was succesfully installed, and both the cooling and temperature monitoring systems were fully operational.  - After aligning the lens with the beam, data were collected for different sensors positions relative to the beam center. We also varied the distance in z between the lens and the sensors.  - Measurements were performed using beams with different dimensions. - The available beam time allowed us to accurately map the readout electronics and to measure the ring radius and its resolution. The results are generally in agreement with expectation. ### H6 Outgoing Parallel: CMS MTD ETL (L. Lanteri) - Very productive week: we tested all our sensors, and managed to characterize pre-series LGADs from two manufacturers - H6 cold box and PI stage worked very well and were instrumental to the success of the data taking ### H6 Main: MUONE ECAL (E. Conti) - ECAL succesfully installed with all ancellary systems: Tested with the laser pulse system: working; DAQ set up and working.   - We have the beam setup files to scan in energy from 10 to 150 GeV (positrons) - Using the beam, the detector has been centered and aligned to the beam line - Ready to start the physics program: - scan in energy; - then dependence with temperature, by changing chiller T - Hardware development for the next days: - SciFi detector prototype, almost ready to be installed - module with (g-2) PbF2 crystals, to be tested in lab before being placed in the beam ### H6 Incoming Main: ATLAS ITK STRIP (Lennart Huth) Programme: Study an IRRAD end of life irrariated R5 module in the telescope with focus on efficiency and noise If time left invest into impriving DAQ system Hardware completly packed and will arrive coming Tuesday by car. Setup and beam: * Typical H6B tracking setup: EUDET telescope and MPI cold box + our own simple mechanics and DAQ system * 120 GeV/c pi+ beam at 1-5e5/spill and wide beam profile * ### H6 Incoming Parallel: ATLAS BCM PRIME (Vasileios Mouzakis) Successfully installed and passed the safety test. Took good data with the single-chip module. We plan to take data with the 3-chip module in the upcoming testbeam.   We would like to thank the whole SPS team for their support. ### H6 Incoming Parallel: CMS PIXEL (Branislav Ristic) Programme: Efficiency and operational stability tests of irradiated CMS Pixel production modules. Special focus will be on inhomogeniously irradiated modules and inter-chip (special geometry) pixels. Setup and beam: * Typical H6B tracking setup: AIDA telescope and AIDAinnova cold box + our own simple mechanics and DAQ system * 120 GeV/c pi+ beam at 1-5e5/spill and wide beam profile ### H8 Outgoing Main: CMS PPS (F. Garcia) The setups were dismounted on wednesday and after the radiation inpection, were moved to the Meyrin to the Lab. From the two setups only one performed as expected and therefore the effort was concetrated on carry out as much as possible scans of different types of planes from the ETROC telescope. A lot of data was collected and analysis is progressing accordenly. The aligment was very good, below a beam profile of one of the plane of the teslecope.  The beam conditions throughout the test beam was excellent in terms of the beam spot position, spread and intensity. Many thanks to Maarten for good job. However, we lost partly some data from long runs due to a magnet problem. Time to time the QUAD18 appears in faulty state and requires immediate intervention. If seen in time is ok, if not all the data then after is not usable. The North Area infrastructure, crane operators were very possitive and fast in addressing our request. Therefore many thanks to them. We will come back soon and keep tuning for more news. ### H8 Outgoing Parallel: EIC DRICH (Please insert your name) ### H8 Main: DRD6 IDEA DRC (Please insert your name) ### H8 Incoming Main: DRD6 MAXICC (Please insert your name) ### H8 Incoming Parallel: DRD6 IDEA DRC (Please insert your name) ### M2 Main: AMBER (Kun Liu) - A leak on the H2 supply to our TPC was found last Friday. The leak was fixed and TPC refilled to operation pressure (20 Bar) on Saturday and Monday. - The updated DAQ firmware with DDR3 support was rolled back due to instabilities over long time. Our expert is still investigating. - A silicon vertex detector beam test is set up in the beam dump area, received safety clearance on Monday and started collecting data. - Other than that, we continue normal data taking whenever beam is available. ### K12 Main: NA62 (Ceoletta Marco) - Issue with MNP33 magnet on 4/6, was faulty sensors and fixed. - Very significant issues with networking on 7/6 and today, problem being fixed with IT and access is open. - NA62 availability from 4/6 ~95%, T10 beam availability >80%. ### H6 Outgoing Parasitic: ATLAS BCM PRIME (Please insert your name) ### H6 Incoming Parasitic: ATLAS MALTA (Please insert your name) ### H8 Parasitic: STRAW TRACKER RD (Please insert your name) ### M2 Parasitic: MUONE (Please insert your name) --- ## AoB --- _Minutes by the respective speakers, edited by M.
