High-temperature performance of solid-state sensors up to 500 °C

Abstract

The applicabilities of single-crystal chemical vapour deposition diamond sensors and 4H-SiC diodes for particle spectroscopy in high-temperature environments are investigated. The spectroscopic performance of the sensor materials is measured as function of temperature, from room temperature to 500 °C. Previously published measurements showed a stable spectroscopic response of sCVD diamond sensors up to 200 °C. In this follow-up experiment, the temperature range was extended up to 500 °C for sCVD diamond as well as 4H-SiC sensors.
