02:44 beam is back
  262   Mon Apr 7 07:09:01 2025 Jelena, GuyAcceleratorBeam interruption, FRS
Beam is gone since 7:02. Control room is notified. Beam is back since 7:14. FRS started taking spills.
  134   Thu Apr 3 23:23:20 2025 Zhang Min, Zhou XuAcceleratorBeam injection change
The SIS operator says that FRS doesn't need beam now, ESR will receive the full SIS beam extraction every 3 secs overnight. All the secondary beams are injected into ESR from now on.
  67   Wed Apr 2 07:33:59 2025 Michael, AlexGeneralBeam gone again
7:29, beam gone again, operators say they need another 5 minutes.
  187   Sat Apr 5 10:51:00 2025 Hannes, CaglaGeneralBeam gone
Beam is gone since 10:45.
According to the main control room there is a problem in SIS18. They are looking into the problem.
  102   Thu Apr 3 01:19:44 2025 Zac, JohanGeneralBeam fluctuations
Beam gone again between 01:14 and 01:18, then again at 01:19. HKR says there are problems with the source.

  83   Wed Apr 2 15:46:24 2025 ID, HA,MWGeneralBeam back in ESR,
beam is back, we started DAQ again. All files created after 15:45 should be good from now on.
  66   Wed Apr 2 07:25:15 2025 Carlo, Chris, Alex, Michael GeneralBeam back
07:20  we have beam back.
  189   Sat Apr 5 11:04:22 2025 Hannes, CaglaGeneralBeam back
The beam is back as before since 11:02.
  242   Sun Apr 6 18:48:36 2025 Shahab, Moriguchi, TakaAcceleratorBeam back
Beam is back now.
  145   Fri Apr 4 08:53:30 2025 Nic, Magda, Ragan, JanGeneralBeam Break
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
