The change of the source happens now
  
  185   Thu Jul 1 23:38:55 2021 IK, KKRunsChange of gas bottleThe gas bottle has been changed and the beam
is back.
  
  191   Fri Jul 2 01:39:51 2021 IK, KKRunsdrop of intensity
We see a drop in beam intensity from 7E9
to 2E8 between 01:30 and 01:43
  
  194   Fri Jul 2 03:10:03 2021 IK, KKRunsdrop of intensityWe see that intensity stabalized at 9E8 which
is smaller then before. 
We neticed this at 2:50, keep observing.
  
  195   Fri Jul 2 03:19:49 2021 IK, KKRunsdrop of intensity
And the intensity is back again to 5E9 at
03:20
  
  212   Fri Jul 2 14:18:04 2021 Pavlos, AlexandreRunsChange of the measurment to 72BrBoth resonators will now be retuned to look
for the isomeric state in 72Br.
