  148   Sat Apr 4 17:32:01 2020 Ragan, Alex, EstherGeneralNo beam in ESRThe beam is coming from SIS but doesn't arrive
in ESR because the quadrupole magnets in
ESR have failed.
  
  150   Sat Apr 4 18:57:49 2020 Ragan, Alex, EstherGeneralTiming problem with SIS & ESR and problems with stackingThere are further problems with beam stacking
in ESR. It works occasionally but keeps failing.
There is also timing problem between SIS
  
  152   Sat Apr 4 22:31:02 2020 Alex, EstherGeneralBeam in ESR lostThe beam in ESR was lost suddenly at ~22:20
due to a power supply failure of the quadrupoles.
