Sat Mar 28 18:11:13 2020, Alex, Yuri, General, no beam in the ESR
|
Yuri and Sergey (on phone) have investigated extensively the problem with having no beam in the ESR. The FRS has been checked and seems OK. The ESR is fine
as well.
The problem seems to be the timing. Ths SIS and the ESR seem to be completely out of synchronization. The on-call service for the control system has been |

|
Attached is a list of all set values for the 5 MSCF shaper modules.
This was done prior to run0251, which served as a final benchmark for those settings.

Sun Mar 29 13:04:32 2020, Ragan, RuiJiu, Runs, run file: 1298
|
The Tl fragments are being stacked (almost ~20 staacks) and tried to store nicely in ESR.
The plan is to see the number of contaminants on the inner detector (CsISiPHOS) after the gas jet is on (Ar gas jet) and minimise this number for different
FRS settings !!

This is a collection of energy spectra of the CsISiPhos detectors from run0251 with primary beam.
There is no good spectra for n-side of Si-pad 1! |

|
Attached are plots for Si-pad 2 with hits from ionization of 206Pb81+ at the target.
The plots are representative for all Si-pads, the pattern is always the same!

|
Yuri sets up FRS with 2 g/cm2 degrader (previous one is 1 g/cm2). The ESR is not changed. The contamination should be less now. |
