Abstract
This paper deals with the determination of electron density in a pulse d surface wave discharge (frequency omega/2 pi=1.1 GHz, pulse duration tau similar to 10 mu s), in an air-like mixture at about 10 Torr in a capillary tube (inside diameter 1.5 mm). A time-resolved diagnostic b ased on microwave interferometry is developed. It is shown that it pro vides both the collision frequency nu and the electron density n(e) ex cept when nu/omega exceeds a certain value (5 for these operating para meters).
