Abstract:

The results of an initial program performed by IRT Corporation in support of the RADCDNA program Radiation Hardened Quartz Process Investigations are presented. Included are calculated depth-dose profiles in the resonator assuming 10-MeV electrons incident on the oscillator package to be used in the resonator evaluation program. Also presented are the results of irradiations of the oscillator package at the RADC facility. Effectiveness of a collimator in protecting oscillator and oven control electronics has been assessed and the results of dose mapping throughout the electronics is presented. Scaling relationships relating dose in the resonator to the dose at an external reference point were developed. Irradiations of a working oscillator were performed to assess the extent of possible experimental anomalies that would impact the actual RADC measurements. The results of the above tasks were evaluated in light of their impact on the RADC program and used to formulate working procedural andor equipment choice suggestions. In addition, a preliminary study has been made of the hardness assurance requirements for quartz used in quarts crystal filters.
