Radiation analyzer

Abstract

To provide a radiation analyzer that can perform analyses by a long-term stable and high energy resolution without correcting a current flowing through a transition edge sensor (hereinafter referred to as TES) or a pulse height value of a signal pulse. The radiation analyzer includes: a TES 1 configured to detect radiation; a current detection mechanism 4 configured to detect a current flowing through the TES 1; a pulse height analyzer 5 configured to measure a pulse height value based on the current detected by the current detection mechanism 4; a baseline monitor mechanism 6 configured to detect a baseline current flowing through the TES 1; a first heater 13 whose output is adjusted to stabilize a temperature of a first thermometer 12 disposed in a cold head that cools the TES 1; and a second heater 14 that is disposed fairly close to the TES 1 and whose output is adjusted to stabilize a baseline current.
