Abstract

Destruction and removal efficiency (DRE) of $SF_6$ was tested with varying degrees of ionization and initial concentrations of $SF_6$. The applied dose of ionization energy varied from 0 to 400 kGy. The initial concentration of $SF_6$ gas also varied from 1,000 ppm to 2,500 ppm. In order to assess the effect of a residence time on DRE (Destruction and Removal Efficiency, %), experiments were also conducted at different irradiation times of 3, 5, 10, 15, and 20 sec, respectively. The DRE of $SF_6$ increased with an increasing amount of dose and current. Regardless of initial concentration of $SF_6$, 90% level of DRE was achieved by applying over 10 mA of electrical current.
