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.
  
  186   Thu Jul 1 23:46:17 2021 IrisGeneralLess beam after gas bottle change?Looks like there is a bit less beam now in
the ring. I just looked at one spectra from
before the gas bottle change and after...

good earlier run to compare.

change is from 23:38:25 (on the 410 MHz Analyzer)

We see a drop in beam intensity from 7E9
to 2E8 between 01:30 and 01:43

is smaller then before. 
We neticed this at 2:50, keep observing.

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