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.
