minutes. According to the info from HKR,
the experts started to repair the magnets

  78   Wed Apr 2 12:13:57 2025 Michael, AlexAcceleratorSome empty injections triggered while beam patterns are changedOperators seem to play with spill cycles,
we get every 1:1 shot, then 1:10 again. During
this, we noticed a few "empty injections"
  
  77   Wed Apr 2 11:09:42 2025 Michael, AlexAcceleratorThe beam is back in the ESRWe have the beam again the ESR since around
11:00.
The Schottky spectra look the same as before.
  
  76   Wed Apr 2 10:55:16 2025 Michael, Alex, WolframAcceleratorNo beam in the ESRSince few minutes do not see any beam in the
ESR (on RSAs). There is beam in SIS and injection
requests from the ESR seem to be there as
  
  75   Wed Apr 2 10:31:15 2025 Michael, AlexAcceleratorThe beam is back from 10:10     
  74   Wed Apr 2 10:05:06 2025 Michael, Alex, YuriAcceleratorNo beam since 09:59The SIS kicker has failed again.

s to 30 s
Triggering only on real injections.
  
  72   Wed Apr 2 09:28:59 2025 Michael, AlexGeneralEmpty injections in the ESRSince the FRS started to take the beam again,
the ESR gets 1/10 shots from SIS. But, the
ESR seems to request about twice more frequently
  
  71   Wed Apr 2 08:47:27 2025 Michael, AlexGeneralThe beam is backThe beam is back. But, the experts have found
a problem with one of the modules of the
SIS kicker magnet. And, currently they have

Since this has happened already few times,
the experts from the on-call duty service

on RSAs. RSAs are still triggering and writing
files, but only see noise. Lassie indicates
