RADIATION ANALYZING APPARATUS

摘要

A superconductive transition edge sensor detects radiation. A wave height analyzer generates an energy spectrum of radiation using a detection signal which is output from the superconductive transition edge sensor. A temperature control section and a base line monitor mechanism acquire a physical quantity of data having correlation with detection sensitivity of the superconductive transition edge sensor. A sensitivity correction arithmetic operation unit associates the physical quantity of a plurality of pieces of the acquired data at a plurality of different timings over a predetermined period of time with the detection signal at a certain timing and corrects the detection signal at the certain timing in accordance with the detection sensitivity of the superconductive transition edge sensor by using information regarding the correlation between the physical quantity of the plurality of pieces of data and the detection sensitivity of the superconductive transition edge sensor.
