plunger run # 208
Beam dump 0.75 enA (given by operators) * 7 (following entry ID#39) = 5.25 enA
Collimator 0.75 enA |
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

|
The counting rate in 511 keV line for sum of the Ge detectors placed at 101, 117 and 143 degrees (with approved ACS). The largest intensity is visible
for Ge at 143 degrees, lowest for 101 deg.
