  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.
  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
  126   Thu Apr 3 17:01:07 2025 CJ Griffin, M Cockshutt, G LeckenbyGeneralMoving PLEIADES detectors in
The inner PLEIADES is moved into position close to the beam.
Device control for the outside pocket is not currently working so that pocket remains in its outward position.

NTCAP/Schottky data acquisition stopped during pocket position tests.

Inner detector (x86l-124 BGO)
Device: GE01DD2IG
Position: +20 mm
Scraping beam: not possible

Outer detector (x86l-131 GAGG)
Device: GE01DD2AG
Position: -127 mm
Scraping beam: 
  281   Mon Apr 7 17:07:33 2025 Team PLEIADESDetectorsMoving 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
  308   Tue Apr 8 10:13:51 2025 Team PLEIADESDetectorsMoved outside particle detector back into parking position
10:16 Moved outside particle detector back into parking position (-126mm)
  322   Wed Apr 9 00:08:30 2025 Sergey, Yuri and XinliangGeneralMove of the scraper positions at ESR
From roughly … to 0:05AM, Sergey moved GEEXDS1HA (not 
changed 
in the end) and GE01DS3HG (changed from -85 to -80 mm) to reduce 
the acceptance of the ESR to improve the mass resolution.

After the change, there are less small traces appearing in the 
413.55735 MHz +/-5 kHz range. 

The final positions of the two scrapers are 
GEEXDS1HA :-10 mm; GE01DS3HG:-80 mm.

Looks a bit more regular now (FRS people having dinner???)
