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. |

Fri Mar 3 10:09:20 2023, IP. KWL, Runs, , General, beam intensity decreased to 0.3 enA (at beam dump) on our request 
|
// we noticed yesterday that GE at 143 degrees counts more than those placed at 117 and 101. The 511 keV line (+ background) is much more pronounced
for Ge at 143 degrees. To investigate this issue we decreased the beam intensity to 0.3 enA ( value given by operators at the beam dump ).
Conclusion - decrease of the beam intensity does not explain above observations (se attached figs) |
|
Fri Mar 3 10:21:18 2023, IP. KWL, Runs, , General, beam intensity back to 1.25 enA at the beam dump
|
| we increased beam intensity to 1.25 enA (readout at the beam dump) |
