RADIATION DETECTOR

摘要

The present invention pertains to the field of radiation detection techniques and can be used for increasing the sensitivity and precision when recording a radiation intensity as well as for increasing the dynamic range of the radiation intensities to be detected. In a first embodiment, the detector includes a photodiode and a load connected in series. The load is connected to the photodiode by its signal output while it is connected on the other side to a common line. The detector further includes a transistor and a request pulse generator. The second electrode of the photodiode is connected to the first electrode of the transistor which has its control electrode connected to the output of the request pulse generator. The third electrode of the transistor is connected to the common line. In a second and a third embodiments, the radiation detector further includes a radiation-sensitive member connected on one side to a voltage supply line, as well as a load connected on one side to the common line. The detector further includes a transistor and a pulse generator, and also includes a capacitor in one of the embodiments.
