194Pb at the Brho of the primary beam before
(=7.2008 Tm).

to recover particle identification now that
beam has returned.

on central orbit was tried.
- quadrupoles tuned and scrapers optimized

  59   Wed Apr 2 00:59:43 2025 Zac, Carlo, ChrisAcceleratorLost the beamBeam was lost from 00:44 until 00:59   
  73   Wed Apr 2 10:02:40 2025 Sergey + YuriAcceleratorESR TimeoutAt around 9:40, ESR timeout changed from 10
s to 30 s
Triggering only on real injections.
  
  74   Wed Apr 2 10:05:06 2025 Michael, Alex, YuriAcceleratorNo beam since 09:59The SIS kicker has failed again.   
  75   Wed Apr 2 10:31:15 2025 Michael, AlexAcceleratorThe beam is back from 10:10     
  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
  
  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.
  
  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"
  
  80   Wed Apr 2 13:27:52 2025 Michael, Alex, MaeveAcceleratorNo beam in the ESRThere is no beam in the ESR since couple of
minutes. According to the info from HKR,
the experts started to repair the magnets
  
  82   Wed Apr 2 15:07:52 2025 Michael, Alex, MaeveAcceleratorStill not a good beam in the ESRThe (power supply of) SIS kicker magnet has
been repaired and the beam has been restored
from about 14:20.
  
  96   Wed Apr 2 23:15:52 2025 Zac, JohanAcceleratorNo injections from SISNight shift starts with no injections from
SIS! We still have triggers; we called HKR
and are waiting for response.
  
  97   Wed Apr 2 23:27:35 2025 Zac, JohanAcceleratorBeam is back 23:25    
  98   Wed Apr 2 23:33:43 2025 ZacAcceleratorBeam is gone at 23:29
