FC Calibration
The Beam digitizer calibration is 106.7 counts/nC
The beam digitizer was calibrated by Erik Søndergaard the 9/1-2015.
The resistance have been measured with a HP High Resistor Meter 4339A @ 100V. The counts was measured with a HP 53132A with a gate time of 10 seconds. The power supply was a Fluke 341A Voltage Calibrator.
