High-pressure xenon (HPXe) ionization chambers are ideal for use in uncontrolled environments, as a detector's response has been shown to be uniform over large temperature ranges (20–170∘C). A cylindrical HPXe ionization chamber, which was configured with a shielding mesh to improve its energy resolution, was designed on the basis of an EGSnrc simulation code to extract an optimal density of Xe gas...
Alpha-particle detectors based on 6H-SiC semiconductor were fabricated and their electrical and radiation performances were measured. Detector structure was Au/Ni/6H-SiC/Ni/Au multi-layer structure. The current–voltage characteristics of the SiC detectors were measured and the radiation response was evaluated by 238 Pu with 5.5MeV alpha particles at room temperature in air. The 6H-SiC detectors...
