Resonator effects of Ar2+ ionic excimer pumped by electron beam

Abstract

The third continuum of argon from 200 to 270 nm is obtained by electron beam pumping argon. With the front mirror and the rear mirror, the resonator effects are observed at 240 and 220 nm. Compared with the intensity of fluorescence, the intensity near 240 nm increases more than 10 times when the resonator is formed. In order to explain the origin of the continuum, the kinetic model on Ar 2 + and Ar 2 2+ ionic excimers pumped by electron beam is built and calculated. Based on the theoretical results, the Ar 2 + ionic excimer should be responsible for the continuum around 240 nm.
