STOP RSA for beam tuning
  147   Fri Apr 4 09:45:02 2025 Ragan, Wolfram, SergeyGeneralElectron Cooler
Regina, Jan, and Markus are in the ESR to check the electron cooler.
  148   Fri Apr 4 10:36:40 2025 Ragan, Wolfram, Sergey, ZsoltGeneralESR setting change from 188Hf72+ to 186Hf72+
ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for the primary beam transmission check is 528 MeV/u.
  149   Fri Apr 4 11:00:35 2025 Ragan, Wolfram, Sergey, ZsoltGeneralElectron Cooler
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. 
  150   Fri Apr 4 11:15:05 2025 Ragan, Wolfram, Sergey, ZsoltGeneralElectron Cooler
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
  151   Fri Apr 4 11:44:31 2025 Ragan, Wolfram, Sergey, Zsolt, MagdaGeneral ESR setting change from 188Hf72+ to 186Hf72+
ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for 
this fragment is 510 MeV/u.Brho = 7.86166 Tm.

  157   Fri Apr 4 16:12:54 2025 JG, IDGeneralpleiades detectors moving
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.
