METHOD AND CIRCUIT ARRANGEMENT FOR COMPENSATING RATE DEPENDENT CHANGE OF CONVERSION FACTOR OF DRIFT-TYPE RADIATION DETECTOR AND DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drift-type radiation detector compensating a rate of dependent change of a charge-to-voltage conversion factor. SOLUTION: In this circuit arrangement for compensating the rate dependent change of the charge-to-voltage conversion factor of the drift-type radiation detector 301, a change of a momentary photon hit rate affecting the drift-type radiation detector is detected. A drain current flowing through an integrated amplifier 302 of the drift-type radiation detector 301 is changed by an amount proportional to the change detected by the momentary photon hit rate (902, 903).
