 Sun Mar 22 17:45:07 2020, Laszlo, General, switching 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.

DSSSD was moved out (HV switched off)
also the scraper was mistakenly moved.

|
Uwe found out, that there was some common ground effect between 90 and 145 degree detectors. after moving the grounds, we could record much more nicer (Gaus
shaped) peaks in the spectra. Now we continue with this settings |

Wed Apr 8 23:02:24 2020, Laszlo, General, lmd to measurement pairing list,
|
I use the following list of lmd files combined to a single root file for each measurement.
It is very important to highlight that sometimes the trigger==1 data got corrupted,massive number of trigger==2 like events appear on the detector as trigger==1
signal, because the gas jet target didn't switch off after its normal phase (gas jet remains ON during injection. Maybe some gas jet issue, maybe some |

Tue May 19 16:48:15 2020, Laszlo, General, E127 beamtime overview,
|
Here is a representation how was the time management during E127. The time, what we could spend with measuring the 118Te(pg), was ~20% comparing to the
given 6days. |

|
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)

Wed May 19 15:09:22 2021, 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.

beam and target alignement was checked by looking at the Xray rates. Best case when:
Target bump (position) SC 9: -18.5mm

|
The vacuum remained in the E-10 range after moving the dsssd. The oscillation in the vacuum.values are due to the
magnets ramping up and down |
