Abstract

This work reports a novel approach employing a retarding field analyzer (RFA) to simultaneously measure parallel and perpendicular ion temperatures. I-V curves obtained by the RFA were analyzed considering the influence of selective ion transmission, and the ion temperatures were evaluated. The RFA analysis yielded parallel and perpendicular ion temperatures of 1:2 eV and 2:1 eV, respectively. The perpendicular ion temperature obtained by an ion sensitive probe was 2:0 eV, demonstrating good agreement with that evaluated by the RFA.
