FREE-FALL DECAY OF A MERCURY VAPOR PLASMA IN THE EARLY AFTERGLOW

Abstract

A free-fall theory is developed for the decay of the average electron number density and of the electron temperature in a pulsed cylindrical mercury vapor discharge plasma using moment equations for the ions with a collision therm for momentum loss, and assuming Maxwellian electrons. The plasma assumption was used. Good agreement is obtained with experimental results on four tubes of varying diameter.
