  323   Wed Apr 9 06:47:51 2025 Esther, NikosGeneralBrief beam interruptions
There was no beam from SIS between about 06:28 and 06:39.

Again from 07:02 to 07:11.

And again from 07:49 to 07:55.
  324   Wed Apr 9 09:30:14 2025 YuriGeneralSlit changing
I would like to close E01 slits a bit more and get 30 min of data with higher 
resolving power.

EEX scraper from -10 now -1
E01 unchanged

  326   Wed Apr 9 10:24:54 2025 Yuri, Sergey, Nikos, EstherGeneralFinal Injection
The a final injection from SIS18 stored at 10:04.
The scrapers were moved out before to get the maximum intensity.
NTCAP is still running, the RSAs recorded the last files at 10:04.
The plan is to keep running like this for about an hour.

Beam stopped at 10:58.
NTCAP and RSAs are stopped.

Screenshots of RSAs showing acquisition settings, for documentation, they show the time / date on the bottom left, in case needed for data analysis.

more screen shots of RSAs.
  3   Thu Mar 27 17:20:40 2025 Esther, Yue, Carlo, Zac, ShahabDetectorsSetup Genesys
We set up the Genesys. Channel map:

tr0:
IO1: Trigger MBS
IO2: Trigger NTCAP
IO3: None
IO4: Trigger RSA01
IO5: Trigger RSA02

tr1: 
None
  46   Tue Apr 1 17:08:13 2025 JG, ID, MC, CGDetectorspleiades in position
The pleiades detectors are now moved into a position which does not disturb the stored beam. 

inner detector: BGO
device: GE01DD2IG 
position: +20mm
scraping beam: not possible

outer detector: GAGG
device: GE01DD2AG
position: -55mm
scraping beam at: -45mm

These positions are fixed, i.e. not moving automatically.
  93   Wed Apr 2 20:57:34 2025 ShahabDetectors10GB cables for the DAQ rack
We have been working together with IT on the speed of data transfer: with the new 10 GB interface we can now transfer data from NAS to Lustre with 400MB/s. From NAS to GPU Computer up to 700MB/s. All cables around the rack are now 10GB capable.
  114   Thu Apr 3 08:02:04 2025 Team PLEIADES (JG, ID, CJG, MC)DetectorsEntering ESR for PLEIADES
We are going to enter the ESR to check on the PLEIADES pocket detectors and install a nitrogen cooling.
  156   Fri Apr 4 16:12:14 2025 Team PLEIADESDetectorsInserting both PLEIADES detectors
We are inserting both PLEIADES detectors step-wise, one by one. Main beam should not be affected too long.
  162   Fri Apr 4 17:13:12 2025 Team PleiadesDetectorsPLEIADES detector out
17:12 We moved the PLEIADES detector out, both are outside now (in parking position)
  192   Sat Apr 5 12:22:12 2025 Team PLEIADESDetectorsPLEIADES inside detector in
12:23 moved PLEIADES inside detector in to 2mm.
  195   Sat Apr 5 14:11:49 2025 Team PLEIADESDetectorsMoving inside pocket detector
14:12 We are moving the inside pocket out for a moment, change the bias
  196   Sat Apr 5 14:55:21 2025 Team PLEIADESDetectorsMoving detectors in again, to 20mm
14:57 We are moving the inside pocket detector in again, this time to 20mm
  206   Sat Apr 5 17:26:48 2025 Team PLEIADESDetectorsOutside 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).
Guess the outside pocket got intimidated by Sergey and decided to get moving again... ;-)

We will take a bit more beam once the setting is stable, but try not to fry another detector.
  207   Sat Apr 5 17:34:14 2025 Team PLEIADESDetectorsMoving outside detector in
17:35 Slowly moving PLEIADES outside detector (GE01DD2AG) in for some data. Clipping ions at -20mm. Leaving detector at -40mm for a few minutes.
  212   Sat Apr 5 19:20:32 2025 Team PLEIADESDetectorsOutside 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:
