find useful for the on-line analysis. 
  1. The first is a simple bash script that

  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.

away the unwanted 78Kr beam (see pictures).
We do not want activation of the beamline.
