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:

Intensity dropped a lot, ion source fix ongoing
ESR access for 5-10 mins to restart PLEIADES DAQ
FRS has also taken beam again, so ESR is sharing

08:55: ESR closed and takes beam again
