|
| I analyzed the first measurement with 206Pb81+ beam, run 250-267. |
|
Wed Apr 1 01:02:24 2020, ruijiu, Detectors, the detector cable is disconnected.

|
Wed Apr 1 01:05:36 2020, ruijiu, Detectors, detector position fixed at 60 mm
|
| The detector cable was disconnected . We entered and reconnected the cable. |
|
Thu Apr 2 12:52:25 2020, ruijiu, General, setup FRS with 2 g/cm2 degrader.
|
| 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. |

Mon Apr 6 14:17:54 2020, Yuri, Shahab, Runs, FRS valves
|
We saw reduction in ESR beam life. It turned out that FRS has opened valves and venting caused us reduction of the quality of vacuum in ESR leading to beam
loss. We manged to closed GEE5VV so that now beam is stable somehow.
