Abstract
A technique of probe measurement is given which allows an easy determination of Langmuir probe curves in a reproducible pulsed plasma. The technique is then used to study a pulsed P.I.G. reflex discharge. Experimental probe curves are analyzed with a theory based on the BBM formula for ion saturation current. Comparison of probe measurements of electron density with the measurements of an 8.5-mm interferometer shows that the probe behavior is properly described by the Langmuir-BBM (Bohm, Burhop, Massey) theory. Also as predicted theoretically, the experimental ratio of floating potential to electron temperature is shown to be reasonably constant over wide variations in plasma parameters.This publication has 9 references indexed in Scilit:
