ENHANCEMENT OF PLASMA DENSITY IN AN ARC DISCHARGE.
Abstract
The use of an electron beam-plasma interaction scheme for the generation and/or amplification of coherent signals in the millimeter wavelength regime requires the creation of a high density stable plasma. A plasma density of approximately 10 to the 15th power particles/cc is required to produce a plasma resonance frequency of 300 Gc. The density in an arc discharge plasma was increased using mechanical and magnetic constriction methods. A density of 7.5 x 10 to the 14th power particles/cc is realized at a discharge current of 4 amperes in argon. Double Langmuir probe measurements of density and temperature in the plasma are presented for zero and finite magnetic field conditions. (Author)
