Abstract: A method for detecting both gamma-ray events and neutron events with a common detector, where the detector includes a layer of semiconductor material bounded by electrodes, and the electrodes include an anode on one side of the semiconductor material and a cathode on the other side of the semiconductor material, includes the following steps: (a) monitoring the electrical signal at each of the anode and the cathode; and (b) comparing the magnitude of the signals at the anode and the cathode, and the transit time difference between the start of the anode signal and the time when the anode signal reaches a maximum, relatively constant value. In the comparing step, predetermined criteria are used to differentiate between gamma-ray events and neutron events.
