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

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.

Hollow cathode life-time prediction from low work function surface coverage evolution [PDF]

, 2008
In this paper a procedure to update the plasma parameters relatively to changes of the hollow cathode surface work function has been developed. This procedure has been validated with experimental results and then coupled with the deposition/desorption ...
