摘要： An X-ray analyzer includes an X-ray excitation device, an X-ray detection device, and a gate valve. The X-ray excitation device includes a sample chamber in which a sample as an analysis target can be disposed. The X-ray detection device includes a TES which can detect a characteristic X-ray emitted from the sample, and a room-temperature shield which surrounds the TES. The gate valve is disposed between the X-ray excitation device and the X-ray detection device. The inside of the room-temperature shield is provided to enable communication with the inside of the sample chamber. The gate valve includes a partition plate provided to enable blocking of a communication between the inside of the sample chamber and the inside of the room-temperature shield. The partition plate has a pressure-resistant X-ray window.

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.
