Reminder: All beam time exceeding the limits of 2 weeks PS beam time and 1 week SPS beam time (added proton and ion 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.
Upcomming MDs:
Upcoming Techncial Stop
Availability of 96.9% Thu 9am - Thu 9am
Main issues:
Main progress last days:
ISIEC submissions received in plenty of time this week, looking good for next week too - thank you!
Some notes/reminders from this week:
Derogations to the CERN safety rules can be issued by HSE for ‘special circumstances’, however these are generally in two categories:
The ISIEC clearance (https://ep-th-safety.web.cern.ch/isiec-safety-clearance) is valid for 3 weeks, if you need to operate for longer than this we have two options:
Stable data taking up to monday 13th. After heavy technical intervention in EAR-1, necessary to move from neutron induced capture measurements to fission studies.
No beam during daily hours on 13 and 14th.
PPAC detectors have been installed.
T09: Good operation. Issue with the power converters gateway caused about 1hr downtime on Tuesday. Beam files set up for HERD. Next week MDX magnet planned to be installed for VLAST.
T10: Good operation.
T11: No user.
Regular user operation. Good week, cumulated ~2.4e16 p/w on T8, see plot below. Also very good beam steering during week 19 (center within +/- 2mm >94-97% of the time on both axis):
Access during Wednesday morning. In IRRAD stop the TE-CRG experiment (still cooling down), all other long-term experiments continue as scheduled and work to setup new beam instrumentation for heavy ion beam in IRRAD Zone 1. In CHARM full exchange of users (SY-RF and SY-EPC out, TE-MPE and BE-CEM in). Testing a second cooldown scheme (beam intensity down to 6E11 48h in advance). We continue until next Wednesday.
=> completed the installation of the test system and conducted safety inspection yesterday.
=> acquired data for 5.0 GeV/c electrons last night and initiating an energy scan for electrons now, ranging from 5.0 to 0.5 GeV/c, follow by a position scan.
=> We anticipate completing the testing by the afternoon of the 21st.
Our detectors are now under test at SPS-H2 (887/PPE172).
We are going to uninstall (from PPE172), transport (from 887 to 157) and reinstall (to T9) our detector on May 22nd.
The ISIEC form has been submitted two days ago.
Muons, electrons and protons/pions are needed.
We need the magnet (with the bending power as much as possible so as. MDX-85/80?) to select gamma-rays generated by electrons.
The EIC dRICH is a prototype of a dual-radiator Cherenkov detector instrumented with a SiPM photo-detection plane to be able to achieve single-photon capability in a ~1T magentic field. The prototype have been developed in the past years with dedicated test-beams. The goal this time is to study in detail the performance of the SiPM readout with, for the first time, a full coverage of the Cherenkov ring. The parameters are photon yield, angular resolution, dependence on the wavelength, efficiency (in comparison with the gas Cherenkov of the beam times).
Patrol of area lost yesterday at 9.20 due to maintenance of TAG42 Pad. Repatrol with SPS foreseen tomorrow.
Experiment ready fo beamtime staring on Monday 20th.
Brief test yesterday at 18h for T4 to check which targets can
be used for upcoming weeks for e± generation in H6/H8 within RP limits. Thank you all for the cooperation.
22nd May T4 target to change to 180 mm from 100 mm.
Target Sharing:
This week - T2 - 100; T4 - 40/T10 - 20; T6 - 50
Wed 22nd May - T2 - 100; T4 - ~ 50/T10 - 20; T6 - 50
H2: Smooth operation.
H4: An issue with moving beam in the V-plane was observed by NA64. First line exchanged a power converter regulation card and the problem was fixed.
H6: Good operation with no issues.
H8: Good operation. XCET.042.474, 519 and 537 tested and found fully functional.
M2: Good operation. CEDAR 089 showed improvements following the fix on the diaphragm.
P42: Good operation.
Very good beam availability since last Thursday, with only long downtime on the night of May 12th (RF issue). We had to open access two times: once for our issues with timing system and another time to replace the faulty valve in TCC8 (VAC.VPGR.101.004.1A).
We would like to slightly increase the intensity on T10, and keep it between 20-21E11.
In period 30.04-15.05.2024 on H2 SPS ALICE/PHOS have been taken measurements of energy and time resolution, linearity for VME and FEC32 electronics. Measurements done in energy points 10, 15, 20, 30, 40, 50, 60, 80, 100, 120, 150 GeV. Very good beam.
Rate characteristics of theALICE/PHOS detector were measured at 10, 50 and 100 GeV (FEC32).
Tests of the electronic card were done, the card meets all technical requirements.
The final version of the photodetector was tested.
We have got big amount of data for future analysis.
Thank you to all teams working on the SPS NA beams, personally to Nikolaos Charitonidis, Bastien Rae, Michael Lazzaroni and the people who helped us during the test.
We installed our detector into PPE172 yesterday. Thanks to Michael for the technical arrangement and James for the safety inspection.
We performed a test in the late night. The beam seems OK but there are still some small problems with our DUT to be issued.
Thanks to Nikos for making the beamfiles and also thanks to Dipanwita for CESAR help in the late night.
Wed 21st (afternoon - night shifts):
Thu 22nd - Sun 25th:
from Sun 25th:
Testing ASIC+LGAd hybrid modules and LGAD Sensors alone for HGTD Phase II upgrade
Setup installed in H6A between Wednesday and Thursday of the last week
So far we are fully complying with our test program - two out of three hybrids have been tested
Plan for the next days:
We want to thank our colleagues of CMS MTD ETL and ATLAS BCM Prime who allowed us to freely organize our accesses, which we tried to minimize but were not few in the first part of the week.
Since our next testbeam campaing will start on the 29 May, on wedensday 22 we will only dismount a minimal part of our setup to not interfere with High rate beam, basically just the MCP
Preparing for test-beam charcterization of H2M samples and MCP-PMT timing performance studies
UA9 detectors have been installed and the commissioning of the 6-plane tracker is going on.
Easy communication with the other team on the line.
Already agreed on how to proceed after the swap as main user.
Thanks to the beam physicists for their prompt attention also during the long weekend.
After this week, we’ll be back on June 12; if this is not an obstacle for the next users, we would like to leave the trigger electronics in the rack in Q40.
Installation activities are progressing in the Tile garage and in counting room:
one new super-drawer electronics module was inserted using the tools and the procedures we are validating for the installation during LS3 (picture show a mini-drawer element).
We meet Maarteen and Silvia on Monday to discuss the preparation status and define beam settings and configurations.
All infrastructure activities are scheduled (Fences removal, vacuum chambers, gas changes in the Cherenkovs, signal routings, etc. etc.)
Latest prototypes of DaughterBoard and Pre-processors (the components going to the FDR late this year) are being tested and FW finalised. Will be mounted at the latest on Wednesday.
Many thank to all infrastructure team for the help and kindness!
Testing the second prototype of the MONOLITH chips with PicoAD gain layer.
We took data overnight (15/05 to 16/05) but our useful rate is a factor 55 smaller than was we used to have in the highly focused, high intensity run together with EP-Pixel 3 weeks ago.
We will focus our efforts on the upcoming week with beam conditions more suited to us.
We will still use the beam for secondary measurements that require smaller statistics.
Data taking proceeding smoothly and successfully.
ATLAS TileCal will be upstream in weeks 21-22. Particle rate will drop too much to perform meaningful measurements. We are happy with the current run and will de-install at the end of week 20.
