 Sat Apr 5 17:26:48 2025, Team PLEIADES, Detectors, Outside pocket "repair"
|
We tried to convince the outside pocket to move, no success. We can hear the "hissing sound" of the pressurized air but no movement. Sergey tried to move
it from the HKR, also no success. After that I tried to move it again from the Messhuette...and the "Out of tolerance" error message is gone, and the pocket
seems to move. (We cannot confirm from inside because the ESR is already closed).

Sat Apr 5 19:20:32 2025, Team PLEIADES, Detectors, Outside detector moved out again
|
19:20 The outside and inside PLEIADES detectors are both moved back into their parking positions. Shifts should continue monitoring the leakage current
on the mesycontrol screens and enter the values every 2h in the Google spreadsheet:

|
Estimation of potential gain by changing. Files from this points are going to rubbish. Potential gains are c. 20%
22:04: The current acquisition window is recording for 2.9 s. And is not recording for 3.9 s. We are running currently with a spill cycle of 5s every repetition.

Wed Apr 2 23:15:52 2025, Zac, Johan, Accelerator, No injections from SIS
|
| Night shift starts with no injections from SIS! We still have triggers; we called HKR and are waiting for response. |
|
Wed Apr 2 10:05:06 2025, Michael, Alex, Yuri, Accelerator, No beam since 09:59
|
| The SIS kicker has failed again. |
|
Wed Apr 2 10:55:16 2025, Michael, Alex, Wolfram, Accelerator, No beam in the ESR
|
| Since few minutes do not see any beam in the ESR (on RSAs). There is beam in SIS and injection requests from the ESR seem to be there as well. |
|
Wed Apr 2 13:27:52 2025, Michael, Alex, Maeve, Accelerator, No beam in the ESR
|
There is no beam in the ESR since couple of minutes. According to the info from HKR, the experts started to repair the magnets (power supplies) used for
extraction and transfer of the beam from SIS to ESR. It is estimated to take about 1 hour. |
|
Wed Apr 2 08:04:47 2025, Michael, Alex, General, No beam
|
The SIS kicker has failed again at 08:01.
Since this has happened already few times, the experts from the on-call duty service are now looking at the problem. |
|
Tue Apr 1 14:54:24 2025, all, General, No SIS beam since 14:35
|

 Tue Apr 1 16:44:32 2025, Jeroen, Esther, General, No SIS beam since 14:35 
|
| Beam resumed at 16:40. |

Sat Apr 5 17:57:08 2025, Ragan, Dima, Zac, Shahab, Calibration, New Settings Resonators
|
New settings for resonators:
410: plunger stay the same

Mon Apr 7 17:26:57 2025, Shahab, Oliver, DAQ, New DAQ Settings
|
new DAQ Settings for the RSAs:

Wed Apr 2 16:28:14 2025, SS, ID, HA etc, DAQ, NTCAP stop/start
|
| NTCAP was stopped and restarted. |
|
Mon Mar 31 17:46:21 2025, Esther, DAQ, NTCAP scaler assignment
|
The setup contains two NI-6612 I/O cards with BNC-2121 connector accessories that provide eight inputs each for TTL scaler signals.
[B]Important: When connecting scaler signals make sure that they are TTL (not NIM)![/B]

Sun Apr 6 16:24:36 2025, Wolfram, Shahab, Moriguchi, Taka, DAQ, NTCAP restart
|
| NTCAP restarted with new timestamp. |
|
Wed Apr 9 11:18:27 2025, Esther, DAQ, NTCAP off, RSA triggers disconnected
|
The NTCAP computer and crate are switched off.
The triggers are disconnected from the RSAs, but they remain on. |
|
Tue Apr 1 15:32:59 2025, Zac, DAQ, NTCAP Restarted
|
| NTCAP Has been restarted (we restart every day around 15:00 so data goes in a new folder) |
|
Fri Apr 4 01:12:03 2025, Shahab, Analysis, NPZ add up script
|
Since there are many NPZ summer scripts around, I thought I would also share mine. This one takes advantage of the power of filelists and has a progress
bar. Creating file lists gives you more control over the range of analyzed data, for example, the command:

Tue Apr 8 09:53:04 2025, Team PLEIADES, Detectors, Moving outside particle detector in for 20min
|
| 9:53 Data taking with outside detector (GE01DD2AG) moved in to -110mm |
