This is the summary of all Si data collected at 6 MeV/u until run174 before the Alvarez problem.
We have roughly 50-60 counts in the peak region.
This data corresponds roughly to 36hours of beam, which means ~1.5 to 2 counts/hour.

Attached is the exported Telegram chat.
There is the simple PDF and the zip-file containing the chat in json-format as well as all media files.

Below are the results from the e-cooler voltage offset measurments done by Regina Hess et al. using the voltage divider (VD).

--7 MeV-- 
Sollwert GECEBG1E: 4008.3 V     
Measured at VD: 3913 V
Offset: -95.3 V

--6 MeV-- 
Sollwert GECEBG1E: 3460.5 V

-- uncertainty --
for E108b we agreed on 10%
maybe further discussion is needed

Attached are the theory K-REC cross sections as calculated by Andrey Surzhykov (August 2021).

They are done for 118Te52+ on H2 at 7.049 and 6.042 MeV/u as well as for 124Xe54+ on H2 at 7.049 MeV/u.


first column - photon angle (deg), second column - cross section (barn/sr). The results are given already in the laboratory frame.

Comment of Andrey on uncertainty:
Important question about theoretical model and, hence, accuracy of calculations. I used slightly improved "impulse approximation" that takes into account momentum and energy distribution of target electron (in initial state). By playing with the models for the Compton profile of target electron, I estimate the accuracy of calculations as 1 %. To be fair, it is rather conservative estimate. I suspect that for large emission angle (around 90 deg) accuracy is even better. But let us stay with 1 %. 

Attached is the header file needed for root analysis.

Here is a run summary of all the calibration measurements performed so far on the three X-ray detectors. 

Logbook from start of FRS until 118Te injection

Here is a setting plan for FRS and corresponding LISE files.
2 LISE files still use the old FRS-ESR optics, one the new with S6 focus on slits. 
But this does not make a big difference for the simulation, only dispersion S2-S6 is lower.
For realistic contaminants you must open the slits at S6 more(~ +/-10mm).
Added a list of fragments and expected frequencies after cooling at 400 MeV/u.
Only nuclides close to 118Te in m/q should be cooled.

By checking the log files we realized that from yesterday 26.05. 13:44 - today 13:05 the FRS degrader was shown as out.
TS3ET7US should be at -420.0mm not at -580mm (=out). This 3.26mm Sci is used as a degrader and is essential.

After recognizing we set the drive controller back to remote and moved the degrader to -420mm (at 13:02)
The wrong values start on 26.05. at 13:44 and show variation until 16:11 until over night it was always shown as out.

It was tested today (~14h) that if you really move it out no beam is injected into ESR, but beam and even Te was observed in ESR last night.

The drive controller was in manual mode and it may not have given correct updates.
But it was also tested today that drives on the same crate get updates even in manual mode (at ~16h with TS1DG5_S and TS3ED7DS).

We also checked graylog. No drive command was issued yesterday in this time period, whereas the drive commands for testing today can be clearly seen.
Yesterday other drives in S4 area on the same controller were tested. This is most likely the reason for the manual mode.

Uli is still working with gas jet target.

There is some problem with the vacuum in SIS and thus data recording is stopped.
