Silicon carbide Schottky diode detector for fusion neutron yields monitoring using associated particle method

The associated particle method is proven to be one of ideal options for D-T fusion neutron detection, acquiring accurate neutron yields by monitoring alpha particle. Semiconductor detectors can be used to detect alpha particle for compact size, high energy-resolution, and stable response. SiC detector with high radiation resistance is benefit for long service time in fusion neutron monitoring. In this paper, a SiC Schottky diode detector is used to detect associated alpha particles for D-T fusion neutron monitoring, and successfully gets accurate neutron yields, being highly consistent with the conventional Si surface barrier detector. It is encouraging to find out SiC detector can afford 2.56 x 109 cm-2 alpha particles irradiation, with slight performance degradation of dark current and energy resolution, indicating that SiC detector is a promising candidate for fusion neutron detection.

Automated summary

The associated particle method has proven to be an ideal option for D-T fusion neutron detection, and SiC detectors show promising performance in accurately measuring neutron yields and withstanding high levels of radiation.
