Title: Measurements of Prompt Radiation-Induced Conductivity of Pyralux®

In this report, measurements of the prompt radiation-induced conductivity (RIC) in 3 mil samples of Pyralux® are presented as a function of dose rate, pulse width, and applied bias. The experiments were conducted with the Medusa linear accelerator (LINAC) located at the Little Mountain Test Facility (LMTF) near Ogden, UT. The nominal electron energy for the LINAC is 20 MeV. Prompt conduction current data were obtained for dose rates ranging from ~2 x 109 rad(Si)/s to ~1.1 x 1011 rad(Si)/s and for nominal pulse widths of 50 ns and 500 ns. At a given dose rate, the applied bias across the samples was stepped between -1500 V and 1500 V. Calculated values of the prompt RIC varied between 1.39x10-8 Ω-1 · m-1 and 2.67x10-7 Ω-1 · m-1 and the prompt RIC coefficient varied between 1.25x10-18 Ω-1 · m-1/(rad/s) and 1.93x10-17 Ω-1 · m-1/(rad/s).
