Jan, Laszlo, Beatriz | General | beam & target alignement | 2021 |
beam and target alignement was checked by looking at the Xray rates. Best case when:
Target bump (position) SC 9: -18.5mm
(We were aiming to keep the particles in the beam at a const. level when target switched ON)

Helmut Weick | General | FRS settings, LISE file | 2021 |
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. |

Jan Glorius | General | GasTarget Operation | 2021 |
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)
For this we use the small silver dewar on the floor there. In case this dewar is empty we have to refill it in the yard.
No need to stop the measurement for this.
2. We have to monitor the LN2-level warning on Ulis web page: http://ulpc24.gsi.de/mediawiki/index.php
In case there is a warning (~12h remaining), we have to refill the big dewar at the target in ESR.
This means we need ESR on TSG with the gate open.
In case the nozzle is clogging and we do not reach reasonable densities anymore and E1 pressure is going down, we have to heat up the nozzle manually.
This can be done at the control panel on the roof of ESR (see 2nd attached foto).
The proceedure is:
1. push "set point"
2. type new value in Kelvin (e.g. 100K for start of heating)
3. press "enter" to apply or "escape" to correct typo
4. monitor E1 pressure (should go up)
