Abstract:

The report deals primarily with pre-irradiation, insource, and post irradiation frequency and resistance measurements of CR-19U crystal units with construction variations. The radiation source used was the Admiral Corporation Co 60 Facility to a dose of 1 x 10 to the 7th power R. Twelve groups with distinctly different construction variations were evaluated. A marked difference was observed in the reaction of the group in which the synthetic quartz was used. Nickel-over-gold electrode plating appears superior. No apparent superiority is evident among bonding materials. Ribbon type support is inferior to the piano-wire technique. A method of increasing the gamma flux at the pulsed reactor by using polyethyene and cadmium is described. Author
