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.

We have two tasks to take over for the target operation:
1. We have to refill the blue LN2 bottle on the roof of ESR every morning (see 1st attached foto)

Intensity from Sis 1.7E9
The intensity is too.low at ESR to be visible. However we could.catch it somehow with Shottky (picture below) |

|
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.

|
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.

|
Maybe, our degrader in FRS was removed by hand at (~13:40 26/05/21)
It is put back now (~13:10 27/05/21)
All runs taken in this period have to be double checked!

Sat Mar 21 12:32:00 2020, Laszlo, General, Estimated target thickness,
|
Target thickness must be like 5mm (was measured with a moving thin wire)
The beam thickness is small because of the low intensity
Maybe we hit the target a bit offset --> less rate?

Pierre Michel and Laszlo go inside the ESR for switching on the MCP detector so that the photons from the gas jet and secondary beam interaction can be
seen.

The full cycle length of ESR with 30 stacks is about 7:45 minutes, out of which 15.5 sec are with target switched ON.
This is without CMB/HTD in parallel. |
