The beam is still unchanged. We just start a run to collect all remaining data.
Data is probably scratch, expect changing conditions at the machines during the run.

No counts in Target ON phase at Silicon Detector. Probably we had only two first shoots from FRS in this run (see picture below)

  199   Sun Mar 22 17:47:27 2020 Laszlo Si, Xrays target density spectra during 118Te afternoon measurement 
We got 30 counts out of this afternoon 118Te run on our Si TargetON histo.
That 1 count at bin (6,10) I dont understand.

Now i can see peaks both at the 35 and 90 angle Xray spectra but not much on the 145 one.
At the end the target density stayed at 8.6E13.

  198   Sun Mar 22 17:45:07 2020 LaszloGeneralswitching to primary beam 
We have finished the measurement with the fragments.

Now Yury will setup up a primary beam through the FRS, but without target in FRS.
We are hoping for increased intensity and stable gas target.
The plan is to make a measurement with and without the scraper in order to see the effect of scraping the Rutherford scattering.
  197   Sun Mar 22 17:35:39 2020 MichaelRunsrun entry - run087.  
Closing file at 17:39, stopping data taking. Yuri will switch to primary beam through FRS without target.

Also a minor observation is, that at the end of the target on phase, the X-ray count rate is going up very high. (Data acquisition was in Jet Off mode)
