Influence of the cathode material in the cathode fall characteristics of a hydrogen hollow cathode glow-discharge

Journal of Applied Physics, 2018
In this work, we present Doppler free two photon optogalvanic measurements to determine the local electric field strength (E-field) in the cathode fall region of a hollow cathode discharge, operated in pure hydrogen, via the Stark splitting of the 2S level of hydrogen.
