  205   Fri Jul 2 11:44:25 2021 Helmut, YuriAcceleratormove scrapers to see effect on unknown lines
We close the arc inside and straight section inside scrapers to narrow and cut the 70Se line.
Then look what the other lines left of 70Se will do.

1st series with E01DS_HI
 -58  - intensity as before
 -52  - still as before
 -50  - still full
 -45  - less intensity but about same width
 -40  - almost gone 
   0  - gone
 -58  - back to old position

2nd series with EEXDS1HG
 16.0 - full
 15.0 - full
 12.5 - less
 10.5 - less intensity
  9.7 - appears only sometimes
  8.2 - gone
 10.8 - middle intensity and more narrow, measure for a while
  206   Fri Jul 2 12:18:35 2021 Pavlos, AlexandreAcceleratore-cooling
Sergey Litvinov will now try to setup the e-cooler to cool the beam in the ESR. 
The data taking has been stopped (except the NTCAP).

  211   Fri Jul 2 13:44:50 2021 Sergey, et alAcceleratorEl cooler
Up to now, attempts to cool the fat line between Se and Ar were conducted. We give up it now and remove cooling
  212   Fri Jul 2 14:18:04 2021 Pavlos, AlexandreRunsChange of the measurment to 72Br
Both resonators will now be retuned to look for the isomeric state in 72Br.

  214   Fri Jul 2 16:14:17 2021 YuriAcceleratorScrapers 4 72Br
Starting 15:15
The scrapers are moved very much close to each other to eliminate all background particles and leaving basically single ions injected for 72Br. Do not wonder, this means that also many empty files are created.
Scrapers:
E02DS3HG -> -40 mm
EEXDS1HG -> +5 mm
EEXDS2HA -> 0.0 mm

One sees probably a decay of 100 keV isomer, see the attached figure at about 18 s
We will run a few hours with this setting

at 17:20 intensity was suddenly reduced. 
Operators checked. Intensity was a bit low and fluctuating for a while (8e8 to 1e9)
Intensity (1.5e9) was recovered at 18:16
