Resumo
The erosion of a thermionic tungsten cathode is studied. Arc burning conditions under which gas–vapor erosion causes cathode mass losses are determined. It is shown that erosion does not depend on the current ripple amplitude and is roughly equal to 2 ng/C. In experiments, the current ripple amplitude ranges from ±1% to ±50%.
