  140   Tue Jun 29 21:10:30 2021 ShahabRuns72-Ge setting
the new setting is roughly 400 khz lower in frequency.
Previous beam time Ge was on 243.100 now it is on 242.74

we decided to use the higher harmonic:

expecting it on 244.66 MHz

Data is being shared on the WWW server.
Time difference between the analyzers is in order of seconds:

time stamp of the 245MHz data is leading those of 410MHz by 21.733 [s]

The last hour before the gas bottle change is summarized here. 
The first pic shows the 410 MHz spectra taken from 22-23h on the 410 MHz analyzer, in time slices of 0.1 sec from 0s-2s.
The second pic shows the spectra in 20ms slices from 1s-1.16s.

The third spectra was taken in May, for comparison.

I don't think we see anything...
