  4   Tue May 4 17:54:08 2021 Helmut WeickSimulationsupdated LISE fileThis file really has the optics like used
in the last ESR experiments.
Now the transmission is also a little bit

  5   Tue May 4 18:25:31 2021 Helmut WeickSimulationscutting of primary beamThe slits at TE4 and TE5 can be used to cut
away the unwanted 78Kr beam (see pictures).
We do not want activation of the beamline.

  6   Tue May 4 21:49:04 2021 Helmut WeickSimulationscut Brho by scrapersThe dispersion from the production target
into the ESR is not matched.
This is not good for momentum acceptance,

start in SIS, at TE3UF target or inside ESR,
choose with GOTO LABEL (G L)after start system

  9   Thu May 6 13:26:56 2021 Helmut WeickDetectorsTE5 profile grids do not workThere are several issues.

1. The stepper motor drive does not react

mg/cm^2 stripper.
This reduces energy of 78Kr from 370 MeV/u
  
  21   Fri May 7 01:07:27 2021 Helmut WeickAnalysismaybe frequency IDWe think we see the frequency range of A/q=2.25
at 243.1 MHz.
This would correspond to L=108.2m and E=386.4
