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

open access: yes, 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 ...
