|
11:10
We have started a new run at the same energy as R53 (250 keV/u) due to an issue with the DAQ pc
Server and DAQ restarted |
|
Fri Jun 6 17:27:03 2025, AY, ST, JM, EM, DB, Run 53 11x
|
Run 53 started at 18:25 (started already earlier but since then data is taken). Everything is running again. We started at 3E12 at/cm2.
Side comment: Gleb told us 1h ago that he will switch to coasted mode and call us back as soon as he is done. So far he didn't call back and
he is not in the office... So we decided to start data taking already. But: the software says that coasting mode is already on, but the graph looks like |

|
Run 52 started at 17:53. Everything is running again. We started at 3E12 at/cm2
D+ beam deuterium target. D+ beam energy is now 0.3 MeV/u. (beam calc calculation is 0.3067 MeV/u).

Thu Jun 5 08:50:00 2025, JM, CF, CB, EW, Run 51 - background
|
09:49
DSSD4 has been biased to 100V in steps of 5V from 60V. It was previously stable overnight at 60V - attachment 1
Will keep an eye on it but looks OK at the moment. Current bias and leakage current - attachment 2 |

|
Tue Jun 3 14:54:29 2025, PMH, ST, Run 48 6x
|
Run 48 started. Everything is running again. We started at 3E13 at/cm2
D+ beam deuterium target. D+ beam energy is still 0.5 MeV/u. (beam calc calculation is 0.5143 MeV/u). See previous entry for beamcalc.
All four detectors positioned fully out and stationary, however we switched off detector #4. |
|
Sat Jun 8 06:13:21 2024, CB, Run 47/48/49 - target issues & tests
|
07:00
After putting the target back, we observe strong periodic (5 s) fluctuations going from 3E11 to 5E12. The reason is unclear. One may warm up
the target to solve this, but will ask Nikos later instead. |

Run 45 started.
D+ beam deuterium target. D+ beam energy is 0.5 MeV/u. (beam calc calculation is 0.5143 MeV/u). See attachment for beamCalc

|
Fri Jun 7 22:33:13 2024, LB, Run 45 - tests on beam-target overlap
|
Tried to double check beam-target overlap by changing beam horizontal coordinate.
In the tablethe counts in the 4000-5200 keV region in each of the detectors are recorded. Counts were taken for a total time of 5 minutes per
beam position. Attached are the xy plots. |
