section the scrapers work better.
One pair of scrapers works best:

profile for 98Mo. Isomer now clearly resolved.
  
  27   Wed May 15 13:39:10 2024 Beatriz, MinGeneralESR settingFrom 13:37 ESR will be changed again. Now
back to the primary beam, it will be attempted
to measure the orbit of the beam.

in https://sparc-daq-02.gsi.de/, the spectrograms
are not being updated. Expected time to recovery

Yuri still tuning the mass resolution.
  
  22   Wed May 15 09:35:08 2024 Beatriz, MinGeneralNo beamAt 9:32 we lost the beam. They have to work
in the Unilac and there will be no beam for
45 minutes.
