we increased beam intensity to 1.25 enA (readout at the beam dump)
Entry  Fri Mar 3 10:09:20 2023, IP. KWL, Runs, , General, beam intensity decreased to 0.3 enA (at beam dump) on our request  Ge_beamInten_03enA_differentYscale.pngGe_beamInten_03enA_sameYscale.png
// 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)
