September 4th: User meeting exceptionally on Wednesday on zoom only (05.09 is CERN holiday).
Updated user schedule v3.0.0. It is based on the updated injector schedule.
Please get in contact, if you want to take one of the weeks without assigned main user - Tanja (tetiana.shulha@cern.ch) is collecting all requests.
Exchange Magnet H2 beamline: planned for 30.7.-1.8.2024:
No Beam to North Area from Tuesday morning until (expected) Thursday afternoon/evening.
Upcomming SPS NA target intensity changes:

E.B. Holzer, M.R. Jäkel
Proton Run 2024
Ion Run 2024
Reminder: Beam time exceeding the limits of 2 weeks PS beam time and 1 week SPS beam time per year need the approval of one of these CERN committees: SPSC, LHCC, DRDC, INTC, RB or IEFC. Consider joining a DRD collaboration, if you require more beam time.
Target intensities:
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
Smooth data taking in all experimental areas, beam in standard conditions.
EAR1: 63Cu(n, g) + one day test of a LaBr detector
EAR2: Ar(n, g) until 31.07
NEAR: Activation measurements
On call number: 67500
General: Some FGCs required restart on 24th July.
T09: Good operation. Beam to be checked with CMS bril after their setup is done. 0.2 s spill length to be requested (limit confirmed with STI, we should not go shorter than 0.2 s).
T10: Good operation. High pressure Cherenkov reinstalled after brief sightseeing tour of North Area.
T11: No user scheduled.
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.
Thanks a lot for the support!
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.
The detectors are in the airport of Geneva.
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.
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
Preparing setup in the lab
Will install two telescopes, DESY table with long plate needed or one DESY with standard plate + XSCA
On call number: 67500

H2: Smooth operation, beamline limited to 150 GeV/c. Quadrupole exchange next week.
H4: Smooth operation.
H6: Brief trip of radiation alarm due to collimator settings in file for previous T4 target and intensity. Sometimes a magnet has trouble reaching the correct current within tolerance at the lowest setting (for 10 GeV beams). Otherwise ok operation.
H8: Good operation.
P42/K12: Smooth operation.
M2: NA64mu installation ongoing. Beam to be checked on Friday.

Detailed program Week 30:
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.
2x assemblies of 3 silicon modules + 2x scintillator tiles boards

Scope of the campaign:
Plan:
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.
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!
Thanks a lot to Laurence Nevay for the support!
Excellent week! A lot of data! Very stable running!
Many thanks to all! Many thanks to ATLAS TRT team for their help with the trigger and constant support during our running period! In particular: Anatoly Romaniuk, Konstantin Vorobev and Konstantin Zhukov.
Thanks to SPS coordinators and H8 org team for their help with the beam! Especially to Maarten Van Dijk.
Now- in the process of shipping our equipment back to US ( issue with EDH form ).
Looking forward to the next test-beam opportunity!
Taking data. See attached slides.
Plan to test new Silicon devices in the frame of the LHCb VELO R&D towards Upgrade II (TimePix telescope)
