  86   Sat Jul 12 10:30:06 2025 Francisco García InfantesReport Experimental SetUp Ca41

I'm attaching a report for the experimental setup so far.

There is a main problem which haven't been solved yet and I don't know if that can cause problem in the future analysis.

Channels #23, #24, #31 and #32 are not working well. The signal os these channels look attenuated from the pulser, make impossible to see then in the Boron run.

As these channels are in the back side of the detector, it could be possible to run like? Unless we have more ideas about to solve the problem.

The front channels work well all of them, and the rest of the back channels work well as well.

I attach the current for the +15 and -15 volt applied to the PreAmp (low voltage) and the leakage current from the detector is 0.1 uA.

  68   Tue Sep 5 16:09:45 2023 EmmanuelDrop in gain for DEED 14

Dear all,

There was an issue with one of the strips of the deltaE detector (DEED 14), for run216644. The gain dropped to almost a factor of 3. Find attached.

Somehow, it was fixed, but still lags, when compared to other strips of deltaE. This was tested for a more recent run, run216651. Find attached.

I also checked a bit older run (run216637) and they look similar.. Find attached. Maybe we should figure out if this will be a problem for the DEED14 strips.

 

NOTE: The plots have the run number at the top-center.

We switched from Aluminium target to Boron Target (number 1) on Tuesday (26th of Sept.). The Aluminium target was placed in the material room by the RP. We will change to LiF (number 3) on Thursday (28th of Sept.)

Setup 5.10.22

dE 20 um (ID 2837-33) and 494 um double sided (ID 1194-9)

46 channels (2 connectors missing)

LiF4 in beam 

dE: Big flat cables from preamp 22 and 23 into 1A and 1B

E: from preamp 24+25 go into 2A, 2B and 3A 3B

LEMO converter box: Cable 1: dE

                                   Cable 3: E n+n

                                  unlabeled cable: E p+n

E detector voltage: -133 V, leakage current -0.53 micro-Amp

dE detector voltage -22 V, leakage current -0.03 micro-Amp

For the E detector one of the edge p+n strip bond-wires is suspected broken.

  42   Thu Jul 27 11:25:35 2023 ClaudiaAl-26 planning meeting summary
  • Start 9th August, access to EAR-2 11 am earliest but can start in rack area before
  • Setup to be used: 1 dE (16 strips, 20 um thickness) + 1 E (16x16 strips, 150 um thickness. We have a spare for each thickness
  • Sample and detectors to be mounted on the same flange

Things to check:

  • alignment with beam centre (lasers and/or gafchromics foils)
  • is the setup stable to knockes, can all detector / sample positions be well reproduced when making changes

Once setup us completed:

  • checks with pulser
  • mounf LiF sample number 3 and run with neutron beam
  • check that all strips have signals
  • confirm shape of gamma flash and that short times can be anaysed in both detectors (~1.8 us after flash)

If everything working:

  • measure LiF-3 and the switch to Al-26
  • towards end of the run we can also measure B-3 and the empty brass frame (Frame without mylar)
  • proton statistics: 1E17 LiF-3, 1F17 B-3, ~3E17 Empty, 5.5 E18 Al-26

Travel times

Nick: 8-16, Annie 8-12, Tom, 7 -?, Claudia, 8-10, Emmanuel asap until end of run

Measurement runs until Octover 2nd. Disassembly by Nick and Emmanuel.

additional trips during the measurement as required (if something breaks/fails etc. )

 

Attached: photos of previous setup

 

TO Do: MCA availability at nTOF for quick noise checks (Nick)

            how many  channels in 14 bit, how many 12 bit (Nick)

          depletion voltages   for detectors (Tom)

          Register the eqipment at CERN as Edinburgh property (Claudia)
