- 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
