Comparison of hollow cathode and Penning discharges for metastable He production

Andruczyk, D; Feng, P X; James, Brian W; Howard, John


The production of helium 21S singlet metastable atoms has been investigated using a hollow cathode discharge and a Penning discharge, under dc discharge conditions. The density of metastable atoms was measured by atomic absorption using the 21S-31P transition (501.57 nm). A range of plasma currents, varying from 16 to 180 mA, and a range of pressures, from 100 mTorr to 5 Torr, were investigated. This work is directed ultimately to the production of a supersonic metastable helium beam for plasma...[Show more]
