Silicon carbide radiation detector for harsh environments
Abstract We used commercial off-the-shelf (COTS) silicon carbide (SiC) ultraviolet photodiodes for measuring gamma dose rates at high temperature. We tested them with Co-60 gamma dose rates between 0.03 mGy(Air)/s and 3 Gy(Air)/s. The diodes show
