Effects of ionizing and particle radiation on precision frequency sources (Proposal for IEEE Standards Project P1193). Technical report
The susceptibility of quartz oscillators and atomic frequency standards to natural and enhanced ionizing and particle radiation is an important parameter in predicting the short and long term performances of these standards in spacecraft. Characterization of the response of frequency standards to ionizing and particle radiation should be based on a thorough understanding of the radiation environment (proton, electron, neutron and flash x-ray radiation and single event upset) and radiation scenarios (dose/anneal cycle, combined environments). The document will present, in detail, the various forms of radiation existing or produced in the low-earth orbit and enhanced environments. In particular, emphasis will be placed on flux, fluence and dose rate levels and interaction mechanisms as pertaining to realistic radiation exposure scenarios. In addition to a discussion of radiation environments (proton, electron, neutron, flash x-ray, gamma and single event upset), selection criteria for radiation sources are presented including dosimetry and procedures for the radiation testing of frequency standards.
