- Detector voltage is 2300, 2800V GEM and Cathode successively. GEM has not any output to the TDC for 5773, 5774.



Run Number Beam Start Time End time Notes
5773 on beam on for 4-10s, overflow
5774 on beam on for 4-10s shutter is close, beam energy is 7.5 MeV
5775 on beam on for 4-10s shutter is open, beam energy is 7.5 MeV
5776 on beam on for 4-10s shutter is open, beam energy is 7.5 MeV
