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. |

The operator is asked to keep the beam dump current not larger than the present value.
Supposed Distance = 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? |

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)
