Detector and method for detection of ionising radiation

摘要

The detector (1) has detector main portion (2) that is made of semiconductor material in which incident ionizing radiation generates free electron-hole pairs which drift in electric field with anode and cathode sides (3,4) of main portion. Sections of the first and second electrodes are arranged next to each other on cathode side and extend across entire cathode side. The potential difference between the first and second electrodes on the cathode side is smaller than the potential difference between third and fourth electrodes (5,6) on the anode side. An independent claim is included for method for detection of ionizing radiation.
