Sat Mar 29 17:19:46 2025, CG, JG, MC, ID, General, Sample data file

Data files written to /mnt/raw.data/e0203_e0018.
From MBS computers:

Sat Mar 29 17:53:13 2025, CG, ID, MC, Electronics, Bias remote control
|
The MHV modules are set up for remote control. This can be accessed via the mesycontrol software running on x86l-128.
A configuration file has been save to: esr/usr/litv-exp/DAQ-control/mesycontrol/pleiades_2025_v2.xml |

Mon Mar 31 17:55:16 2025, JG, DAQ, DAQ overview
|
The DAQ is running of 4 different nodes/PCs, that can be accessed by ssh using the user litv-exp.

This is the list of scaler channels used at the VME ESR DAQ on x86l-204:

Mon Mar 31 18:35:46 2025, JG, DAQ, lmd files on ESR NAS
|
The files of each MBS node or the timesorter are written to the ESR NAS by the RFIO server.
The server is running on the virtual machine atprfio.gsi.de.
The NAS is mounted there and we write data to the subfolder: /mnt/raw.data/e0203_e0018/

Tue Apr 1 17:18:10 2025, ID, MC, CJG, Detectors, Both PLEIADES detectors in beam
|
We started inserting the inside and outside detector, see

|
Tue Apr 1 22:41:52 2025, CG, Detectors, Climbing leakage currents 
|
The experiment has been running stably during the afternoon.
DAQ rates have remained constant and the frequency of hits in the Go4 has remained 1 hit every ~few mins.
|
|
Tue Apr 1 23:00:41 2025, CG, General, Run stopped and detectors moved back
|
Due to the continued rise in leakage currents, I have stopped the run, moved the detectors completely back and turned off the
bias to all detectors.

Thu Apr 3 13:09:28 2025, JG, DAQ, 194Pb MBS settings
|
The settings of the MBS daq during the first data taking with fragments around 194Pb (W.Korten experiment) was not entirely correct:
1. both FEBEX nodes had the very same sub-sytem identifier 0x200. The timesorter did merge the two data streams into the lmd files. Now the events cannot |
|
Thu Apr 3 13:24:31 2025, CG, Detectors, Bias problem diagnosing
|
During an access break to the ESR, I made a few tests with the bias scheme to see if we could better understand some of the weird quirks.
Two detectors showed likely shorts during initial setup - these detectors were still cabled to the bias network though.

Thu Apr 3 14:53:13 2025, ID, Detectors, Link to leakage current Google doc
|
Please enter the leakage currents from the mesycontrol every ~1h into this Google document:

|
Thu Apr 3 17:37:04 2025, CJG, GL, MC, General, Detectors in position, taking data
|
The inner detector was moved into position.
The device control for the outer detector is not responding and I am not an expert/don't know how to make it work.

|
Fri Apr 4 16:12:36 2025, CJG, GL, MC, JG, ID, General, Moving PLEIADES in
|
186Hf now stored stably in the ring.
Will move both detectors in to position.
|
|
Fri Apr 4 16:27:11 2025, CJG, GL, MC, JG, ID, General, PLEIADES in position
|
Inner PLEIADES detector moved into position at +2mm.
Again, the outside pocket cannot be moved.
