17:12 We moved the PLEIADES detector out, both are outside now (in parking position)

the new scraper setting for good isochronicity but still acceptable intensity losses is:
Done at ~ 15:00 today.
GEEXDS1HA (outside)          =  -8 mm
GEEXDS1HG (ToF-det-aperture) =  20.5 mm
GE01DS3HG                    = -84.2 mm  (fully open is -130 mm)
in addition, a detector pocket is in GE01DD2IG = 1.7 mm

A Bio-REM detector on the roof of ESR caused an alarm and shut down the whole accelerator.
Too much primary beam going to ESR, noe we avoid it by catching the primary beam at TE4 slits.
The distribution on current grids looks liek in the LISE simulation, we cut at 5mm.
The beam come sin three charge states tehouter ones 82+, 81+ anyway do not make it to ESR, we need to cut also the 80+ at least half.
Then the dose rate on ESR roof is much lower 0.8 uSv/h -> 0.2 uSv/h.

Code used to add up injection data.

We started moving the pleiades detectors at 16:13 04-04-2025.

We have the inside pocket (GE01DD2IG) at 2mm. 
The outside pocket (GE01DD2AG) cannot be moved by the Device Control program, some problem with the tolerance (error message: outside of tolerance). Need to go in in a short break and check what is wrong.

We will partly scrape the beam.

We are inserting both PLEIADES detectors step-wise, one by one. Main beam should not be affected too long.

Tuning is finished, 186Hf is running. Sharp peaks now.

186Hf screen shots with better resolution

Lassie screen shots 186Hf

186Hf, 510MeV/u of 208Pb beam, ecooling not working 

ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for this fragment is 510 MeV/u.Brho = 7.86166 Tm.

No additional HV. So, have to proceed without the cooler. 
Spare Power supply did not work either, we will not be able to use the cooler for the rest of the experiment

Electron cooler anode voltage needs a repair which might take 20-30 mins. If it takes longer, we'll proceed without a cooler curve measurement. 

ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for the primary beam transmission check is 528 MeV/u.

Regina, Jan, and Markus are in the ESR to check the electron cooler.

STOP RSA for beam tuning

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
