GR trouble shooting
TDC1L is missing –> definition of the analyzer
ADC LR correlation
HV module doesn't accept the change of voltage ←- connection of the cable was not good
Plastic scintillators' signals are not good.
–> Spark? each signals of shape and counts should be checked
–> If the signals are strange, take data with DAQ. The trigger may be changed
–> Trigger should be made by three plastics
Beam doesn't come
When we change the GR angle from 8.5 degree to 0 degree in order to tune dispersion matching mode, the beam did not come.
–> Scattering chamber Faraday Cup is in the path of the beam.
