A detector and a method for the detection of ionising radiation are proposed. The detector () exhibits a detector body () made from a semiconductor material in which incident ionising radiation generates free electron-hole pairs, a cathode side () of the detector body () to which the free holes generated drift in an electric field, an anode side () of the detector body () to which the free electrons generated drift in an electric field, at least two electrodes () on the anode side () and at least two electrodes () on the cathode side (). There is a potential difference between the electrodes (). The potential difference between the individual electrodes () on the cathode side () is smaller than the potential difference between each of the electrodes () on the anode side () on the one hand and each of the electrodes () on the cathode side () on the other hand. As a result of irradiation of the detector body () with ionising radiation, electron-hole pairs are generated in the detector body (). Signals are detected at the electrodes () on the cathode side. The difference is calculated and evaluated from these signals. 1.
