East Area Users Tour de Table
T8 Main: IRRAD/CHARM (S. Fiore)
Good week in terms of delivered protons.
In IRRAD continuing cold irradiation experiment with ATLAS iTk strip modules and all other long-term standard irradiation experiments (TE-MSC, EN-MME). Moreover, before the end of the week another experiment (INFN-LHCb) will start using the IRRAD shuttle system.
In CHARM test by SY-EPC ended, new test by TE-MPE started, BE-CEM modified setups. A couple of quick interventions on CHARM infrastructure yesterday (pressurized air leak and cable tray loosened). TID was not optimal due to thick samples in IRRAD.
T9 Outgoing Main: MPGDCAL (Anna Stamerra)
- Data taking went smooth
- We perfomed X&Y scan on the 20x20 pad chambers without absorber moving the desy table
- We included absorbers in the setup and started pion energy scan from 3 GeV to 11 GeV
- We dismounted the setup yesterday and by 9.30 we were out of the area
Thanks a lot for the support!
T9 Main: CMS BRIL (Olena Karacheban)
Setup is mounted. Many thanks to the craning team for help and to Andre and Bane for the telescope assabbley.
We are debugging the setup with muon beam, later today will check the beam files for protons and set up the beam with Dipanwita.
0.2 s spill will be needed toward the end of the week, we will call CCC in advance.
We are planning to move out the setup on Wednesday morning, we will talk to next users to agree the time.
T9 Incoming Main: STCF ECAL&PID (Week 31) (Yunlong Zhang)
The detectors are in the airport of Geneva.
T10 Outgoing Main: IDEA CC (Nicola De Filippis)
Experiment completed on July 24. The area was emptied on July 24 at around 8:30.
We took data until the last night. Everything was cleaned up at T10.
T10 Main: BL4S (Sarah Zoechling)
Experiment set up yesterday (scheme presented last week).
Many thanks to Abou and his colleagues, to the gas team, to Maarten and EA colleagues, and to BI team for their help!
Safety check will take place this morning.
Beam hopefully today.
Main goals are to verify and optimise the measurement principle of the BL4S winning experiments (both teams developed muon detectors).
Stretch Goal is to test the possibility of using a WENDI detector for spallation experiments in future BL4S editions.
Upstream: XCET and Scintillator of T10, BL4S 2x finger scintillator on stand, XSCA for WENDI (stretch goal, tungsten target on tripod not in picture), BL4S 3x DWC (out of which the first one mimics the “DUT”) on XSCA
Downstream: BL4S 1x scintillator (paddle) on stand, BL4S 1x scintillator (column-shaped) and 1x calorimeter on DESY table
T10 Incoming Main: ALICE ITS3 (Week 31) (Paolo Martinengo)

North Area Users Tour de Table
P42-K12:
Main: NA62 (Jurgen Engelfried & Joel Swallow)
- Since last Wednesday we are taking normal intensity (~21 units on T10) Kaon data. We are very happy with the quality of the beam extraction; the 50Hz component seems to be under much better control now.
- We will stay at this intensity until Aug 2, when we would like to switch over to DUMP mode, with higher intensity, around 45 units. For the exact time of the changeover we are flexible and will agree with Johannes/Nikos a time. We will stay on higher intensity for 10 days, e.g. until Aug 12.
- We noticed (for example this morning) the switch-off of our beamline magnets. Usually, the P0Survey moves our taxes in case of a magnet failure; but this morning nothing moved. Is there now a new condition in P0Survey exldung closing of the taxes in case of the energy-saving switch-off?
M2:
Main: NA64mu (Please Put Your Name Here)
H2:
Main: NA61 SHINE (B. Maksiak, P. Podlaski)
-
Relatively smooth data taking last week
-
Beam intensity varies and its position moves frequently:
-
Fire alarm: On 24.07 our alarm went off in the huts with time projection chambers. Only the verbal alarm went off. No smoke was detected. Firefighers came, assessed that it was false alarm. We continued.
-
Data taking until nearest Tuesday.
Incoming Main + No beam: CMS HGCAL (Chiara Amendola)
2x assemblies of 3 silicon modules + 2x scintillator tiles boards
 |
 |
Scope of the campaign:
- data-taking with full depth readout (front-end to back-end)
- test within magnetic field at M1 (3T), close-to-final on-detector electronics
Plan:
- installation ongoing since yesterday
- mechanical and movement tests for box manipulation and modules insertion
- routing of powering and readout connections
- safety clearance
- secure magnetic elements of the connections to cooling unit
- tentatively: M1 magnet starting 26/07
- pending readiness of the back-end devs
- main beam users starting 31/07
- we will need the scintillators for triggering
H4:
Incoming Main: NP04 (Week 31)(Christos Touramanis)
Weeks 28-29: smooth data taking, collected 1 GeV both polarities for pion-Argon cross-sections as planned.
On Monday 22 July at 2:58am we noticed extra triggers in our TPC and event displays showed increased rate of through-going MIPs, akin to lost muons from primary target. Reported to CCC but got no explanation, aparently there had been no change (?).
Weeks 31 onwards: continue the same, one of our five weeks to be at 5 GeV for kaon-Argon cross-sections.
Nothing special to report or request.
Main: DRD6 OREO (R. Negrello)
- Please, see attached slides on Indico for EURO-LABS questions
- Yesterday we installed our experimental setup. Everything went smoothly
- The installation and pre-alignment required some times, therefore the Physical program will start today
- A special thanks to
- Sylvain for all the support inside the experimental area
- Nikos for the assistance about the beam files
- To all the CERN staff for making our beamtests possible
H6:
Outgoing Main: DRD6 MAXICC (Marco Lucchini)
All good besides a few magnet issues and some beam down time. We have run with mixed hadrons 120 GeV beam file fo 10% of time, then muon 120 GeV for calibration and electrons from 10 to 100 GeV. Happy with the beam quality and data taken.
We have characterized our detector response as a function of impact angle and beam energy and completed comparison of various detector technologies.
We are grateful to all experts from SPS who made this possible!
Main: EP FTS (L. Martinazzoli)
- Installation concluded successfully yesterday
- Currently commissioning the set-up
- Starting data taking with crystal calorimeter prototypes
- MIP studies over the weekend

AFP (Tomáš Komárek)
- repeated request to cancel or move weeks 32+33 (August) at H6 that still persist in latest schedule version
- the later the better, if not possible, cancel entirely (HW to be tested will not be ready)
- there were hints of a chance to get week 41 in October, any update?
