Abstract


Since emission component BaF2 crystal temperature effect and a shorter decay time of light , China Institute of Atomic Energy through detailed design studies, proposed the use of BaF2 as fast time-resolved α particle detectors . This paper describes the design of BaF2 detector assembly and temperature changes associated with a series of performance tests. BaF2 detectors are designed assembly includes a crystal material selection, packaging methods reflective layer , a light guide material selection and transmission testing. With temperature changes the relative performance tests include α particle detector energy resolution , time resolution , and the particle screening capability. And finally the temperature variation of the pulse pick- α pulses , verify and analyze the fast and slow components of the time resolution of. The results showed that , BaF2 detector energy resolution , time resolution , and the particle screening capabilities are greatly with temperature changes . At room temperature , BaF2 detector has reached the picosecond time resolution order .
