A Study to Determine the Presence of Voltage Breakdown Due to Proton Irradiation in Polymeric Materials.

Abstract

A study was made to determine proton-induced voltage breakdowns in a series of polymeric materials: Kapton (H-film), Teflon (TFE), Pyrrone, Mylar, and polyethylene. Proton energy was varied from 0.40 to 3.25 MeV with a flux of 10(exp 9), 10(exp 10), 10(exp 11), or 2 x 10(exp 11) protons/sq cm -sec. Samples were irradiated to a fluence of 10(exp 13) to 5 x 10(exp 14) protons/sq cm for each test. Sample temperatures were 27 deg C and -134 deg C. No charge storage of induced voltage-breakdown effects were observed. This observation is in sharp contrast to the numerous induced voltage breakdowns observed for electron irradiation of similar types of polymeric samples. A theory developed by Nichols and van Lint predicts that a behavior of this type should be less prevalent because of proton rather than electron irradiation.
