keyword=Compton photon asymmetry assymetricalI tried to increase the HV on the PMT and different gains to see if the
assymetry between laser L and laser R was due to bad ADC channel or non
linearities or electronic noise. But it seems the results did not change
much. Though keeping everything constant we should be able to monitor big
changes in polarization.
I am still puzzled about the origin of the difference.
It seems vertical scan did not help either.
Maybe possible misinditenfication of the laser state with the new laser.
