Available in PDF, EPUB and Kindle. Book excerpt: Tetraglycidyl 4,4'-diamino diphenyl methane epoxy cured with diamino diphenyl sulfone was used as a model compound. Computer programs were developed to calculate (1) energy deposition coefficients of protons and electrons of various energies at different depths of the material; (2) ranges of protons and electrons of various energies in the material; and (3) cumulative doses received by the composite in different geometric shapes placed in orbits of various altitudes and inclination. A preliminary study on accelerated testing was conducted and it was found that an elliptical equitorial orbit of 300 km perigee by 2750 km apogee can accumulate, in 2 years or less, enough radiation dose comparable to geosynchronous environment for 30 years. The local plasma model calculated the mean excitation energies for covalent and ionic compounds. Longitudinal and lateral distributions of excited species by electron and proton impact as well as the probability of overlapping of two tracks due to two charged particles within various time intervals were studied.

Available in PDF, EPUB and Kindle. Book excerpt: The relation between radiation effects and the type of incident radiation is discussed on the basis of available theory. Radiation effects can be separated into three categories: displacement, transient, and chemical radiation effects. Within each category the primary radiation interactions can be utilized to determine the relative effectiveness of different incident radiations in producing the effect. Components and materials for use in space applications are discussed in order of their sensitivity to space radiation. The total environment must be simplified to develop radiation effects test programs. The use of theoretical information in establishing the validity of these simplifications is discussed. Finally, the relative merits of three classes of hardening methods (shielding, component and material substitution, and system design) are discussed.
