Semiconductor detector, particularly pn charged coupled device detector, for radiation detection, has guard ring, selection anode arranged within guard ring for reading out radiation

摘要

The semiconductor detector, particularly pn charged coupled device detector, has a guard ring (12,14), a selection anode (3, 4) arranged within the guard ring for reading out radiation generated signal charge carrier (e) and a discharge contact (9) arranged outside the guard ring for separating the aggregated signal charge carrier from the selection anode. The device also has a under breaking (15,16) in the guard ring and a controlled gate (17,18), which is arranged on the under breaking in the guard ring. An independent claim is also included for an operating method for a semiconductor detector.
