Abstract: The ability of a silicon carbide radiation detector to measure neutron and gamma radiation levels in a TRIGA reactor''s mixed neutron/gamma field was demonstrated. Linear responses to epicadmium neutron fluence rate (up to 3/spl times/10/sup 7/ cm/sup -2/ s/sup -1/) and to gamma dose rate (0.6-234 krad-Si h/sup -1/) were obtained with the detector.

Silicon carbide become generally known as attractive material for demanding mechanical and high-tempera-ture appliion, as well as for use in abrasive, erosive, and corrosive media. Also, SiC is semiconductor of great interest in high-power, high-temperature
If the IGBTs are replaced with wide band-gap semiconductors, specifically silicon carbide FETs, frequencies can be pushed much higher, with better efficiency than IGBTs. Filtering is then easier, so motors operate more efficiently, and faster switching enables better control of the motor to help eliminate effects such as torque ripple which produces audible noise and motor wear.
