MINIATURE NEUTRON DETECTOR DEVELOPMENT. Final Report
Work on the development of miniature silicon carbide neutron detectors undertaken in the period from June 22, 1961, to June 1962 is reported. A major problem area is the development of surface junctions suitable for neutron detection. Diffusion techniques appeared highly promising for the production of such junctions. Accordingly a diffusion furnace for accomplishing this was set up and a diffusion process developed. Contacting and electrolytic etching procedures were developed for preparation of a diode suitable for radiation testing. The processes were successful and surface junction diodes capable of counting particles were produced. The ability to count particles at temperatures up to 700 deg C was demonstrated. Another important area is the evaluation of the junctions under simulated operating conditions. The equipment required for use in irradiation and annealing studies with the Van de Graaff generator was assembled. The equipment was used for evaluation of the SiC diodes at high temperatures.
