Electric Field Measurement of a Neon Hollow-Cathode Discharge by the Optogalvanic Spectroscopy with Two-Step Laser Excitation

摘要

Optogalvanic spectroscopy with two-step laser excitation was successfully applied to the electric field measurement of a Neon hollow-cathode discharge. Experimental results of the radial distributions of electric field and charge density in the cathode-fall region are presented.
