Abstract

The electron attachment rate constant ka for CH3Cl and C2H5Cl has been measured as a function of the gas temperature and the mean electron energy. At room temperature these molecules exhibit exceedingly small electron attachment (ka < 10-14cm3s-1 for CH3C1 and ka ~ 10-13cm3s-1 for CH3C1) which increases greatly with small increases in T (i.e., molecular internal energy). In fact, it has been found that as T increases from 400 to 750 K the electron attachment rate constant over a wide range of mean electron energies below ~ 1 eV increased by over 4 × 103 times for CH3C1 and by ~ 50 times for C2H5C1. In this paper we report our findings on the temperature enhanced electron attachment to these two molecules and indicate their potential use for dielectric and pulsed power switching applications.
