“…The problem, though, is how does the discharge transient couple into the spacecraft system? Coupling has been addressed but has not been adequately treated in charging studies to date [65][66][67][68]. An attempt at modeling the coupling phenomenon for a flight program was conducted for the Voyager program using an EMC code called Specification and Electromagnetic Compatibility Analysis Program (SEMCAP) [69,70].…”

“…In this case we deal with the radiationinduced breakdown and the accompanying rf interference causing transient or permanent damage to the low level electronics [2,3]. Recently, a radiation diagnostic technique to map space charges in dielectrics has been developed [4] which draws heavily on the behavior of RIC in a specific dielectric under investigation.…”

Chemical aspects of the radiation‐induced conductivity in polymers

It has been demonstrated that radiation-induced conductivity (RIC) is strongly dependent on the chemical structure ofthe macromolecules, this dependence being influenced by the position of the active molecular group acting as a hopping center for charge carriers: main chain vs pendant case. Both RIC magnitude and its nature (free ion vs geminate) are affected. Annealing of the radiation-induced conductivity (RIC) in four common polymers (PS, PET, LDPE and PTFE) continuously irradiated in vacuum to doses of about 5 x 10' Gy has been studied. While substantial recovery (up to 75%) has been observed in PS and PET, only steady degradation of RIC has been encountered in LDPE and especially in PTFE (annealing at elevated temperatures has been fulfilled only in air). Unlike other polymers tested, PS shows recovery that depends critically on the surrounding atmosphere (air or vacuum).To describe these results one relies heavily on the radiation-induced oxidation as a chain radical process with degenerate branching (a case of LDPE and PTFE) and catalytic recombination of macroradicals (as in PS).
