Started after beam current was reduced by a factor of 2
plunger run # 116
Earlier: CUP#6 100 enA
Now: CUP#6 50eNA
Beam dump 1.8 enA
Collimator 0.8 enA
The operator is asked to keep the beam dump current not larger than the present value.
Supposed Distance = 10 um
position of the target = 10 um
micrometer = 11.7 um
Voltage = 7.9 V
Plunger off set 60 um
Which means we are running 60 um + 10 um (read from position window of plunger) = 70 um.
Observed that detectors at theta 143 degrees count most. Is this because they see beam dump? |

|
New target mounted.
106Cd 1 mg/cm2
181Ta 1.2 mg/cm2
Problems in alignment. Offset of 100 um, in spite of the fact that a gap is visible at this distance, and a hair could be moved in between stopper and the target.
Decided to close and pump anyway, after several attempts to improve the alignment.
Stopper same as before, slightly more stretched. |

Beam energy measured: 148.2 MeV
Mind that this may be an overestimate (by ~1-2 MeV) |

|
Beam on the target:
target+stopper+beam dump: 25 enA (1.7 pnA) not stable
5 mm collimator: 0.8 enA
data taking continued with run 0023 |
|
Thu Mar 2 16:40:45 2023, MP, Runs, , General, changing the plunger distance to minimum.
|
Run 31 was stopped, because plunger distance is reduced to the mininimal one.
It takes time, in the meantime, after some break, run 32 was started, with no beam. |

Sun Mar 5 16:58:45 2023, MP, Problems, , Other, run 37 crashed, run 38 junk
|
Run 37 stopped by itslelf at 15:43. This was noticed at about 16:10 by observing that grafana data rates do not change.
Stop at Run COntrol. LF looks disabled.
Attempt to restart normal way --> run 38 --> failed
Attempts to load topology failed.
Cannot any more refresh or load the Run COntrol web page (192.168.0.133:5000)
Grzes is trying to fix the problem remotely, while we are starting changing of the target....
