Fri Apr 4 17:13:12 2025, Team Pleiades, Detectors, PLEIADES detector out
|
17:12 We moved the PLEIADES detector out, both are outside now (in parking position) |
|
Thu Apr 3 08:02:04 2025, Team PLEIADES (JG, ID, CJG, MC), Detectors, Entering ESR for PLEIADES
|
We are going to enter the ESR to check on the PLEIADES pocket detectors and install a nitrogen cooling. |
|
Fri Apr 4 16:12:14 2025, Team PLEIADES, Detectors, Inserting both PLEIADES detectors
|
We are inserting both PLEIADES detectors step-wise, one by one. Main beam should not be affected too long. |
|
Sat Apr 5 12:22:12 2025, Team PLEIADES, Detectors, PLEIADES inside detector in
|
12:23 moved PLEIADES inside detector in to 2mm. |
|
Sat Apr 5 14:11:49 2025, Team PLEIADES, Detectors, Moving inside pocket detector
|
14:12 We are moving the inside pocket out for a moment, change the bias |
|
Sat Apr 5 14:55:21 2025, Team PLEIADES, Detectors, Moving detectors in again, to 20mm
|
14:57 We are moving the inside pocket detector in again, this time to 20mm |
|
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).
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. |

Sat Apr 5 17:34:14 2025, Team PLEIADES, Detectors, Moving 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. |
|
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:

|
Mon Apr 7 10:40:33 2025, Team PLEIADES, General, Enter ESR
|
At 10:45 we will enter the ESR and install a remote oscilloscope for the PLEIADES outside detector. Should take only 10 "GSI" minutes ;-)
After that, ESR tuning to 192Pb can start. |
|
Mon Apr 7 17:07:33 2025, Team PLEIADES, Detectors, Moving OUTSIDE PLEIADES detector slowly in (and out)
|
17:08 Tried to move outside particle detector (GE01DD2AG) in - it is stuck again :-(
17:18 Sergey tried to move it, now it moves again. Moved to -100 mm.
17:30 Moved detector to outside parking position |
