  • Drive and measurement circuit for a photomultiplier
    Patent number: 8618457
    Abstract: A method of measuring an anode current in an electron-multiplier device having an anode, a cathode, dynodes and a voltage divider network for applying voltages to the dynodes, which method includes applying an HV positive voltage to the anode and intermediate voltages to the dynodes, the cathode being at or near circuit ground potential, conducting dynode currents through or in parallel to the voltage divider to a point substantially at cathode potential, and deriving from those currents a current representative of the anode current.
    Type: Grant
