Shahab | Runs | SIS Kicker problem | |
After calling ESR on-call duty (M. Steck) he confirmed that the ESR is fine and suspected the SIS kicker modules.
SIS operators then checked and could confirm that module 5 is out of order and module 4 sometimes works sometimes not.
They asked me I said better to run as good as possible with lower number of modules until the end of experiment, then later change the module. because otherwise changing module might take time.
they tried to increase the kick angle to check if they can move the spot to the center.
some shots went well but mostly failed.
they decided to call the Rufbereitschaft.
meanwhile I started the run number 93 to at least collect some data from some of the correct shots.
if counts are too high I will stop it.
let's see. |
