Sat Apr 4 17:32:01 2020, Ragan, Alex, Esther, General, No beam in ESR
|
The beam is coming from SIS but doesn't arrive in ESR because the quadrupole magnets in ESR have failed.
Update (18:01): Problem has been resolved. |

|
10:51 am the CsISiPHOS is moved to 65 mm from 60 mm.The spot on the DSSSD is changed by 5 mm which confirms the hit of the beam.

|
Alex and Pierre-Michel applied 1500 V to the anode and adjusted the threshold in Messhute.
x1 signal was small & noisy and rest of the signals were fine. |
|
Sun Mar 29 21:55:47 2020, Ragan, General, MWPC
|
| Alex goes to Messhute to check the signals from MPWC. After he completes, we start with the measurements with the primary beam ) |

Tue May 28 08:36:14 2019, Jan, DAQ, MBS start & RFIO server
|
You need a DAQ-PC and the RIO crate computer.
All of the DAQ proceedures laid out here are operated from inside the DAQ screen session.
Right now for e121 the following DAQ-setup is used: (might change in the future)
