Plasma resonance in argon and neon was studied by a microwave method which afforded a measure of the electron number density. Resonance was excited by an R.F. signal transmitted along a strip-line enclosing the discharge tube. The resonance occurrence was determined by measuring the transmitted power as a function of discharge current and exciting frequency. Data are presented showing the current for resonance as a function of resonant frequency for several gas pressures. In argon, measurements were made for pressure in the range from 0.001 to 0.05 mm Hg. In neon the pressure range was 0.01 mm Hg. Theupper pressure limit was determined by the Q of the resonance and the lower limit only by ability to maintain a normal glow discharge.
