Objectives of the research are: (1) to uncover new principles or techniques from which a CW source of electromagnetic radiation for the low millimeter and submillimeter wavelength range can be developed; and (2) to develop suitable detectors, components, and measuring techniques for evaluating and using the radiation as a diagnostic tool for plasma physics. Rarther experimental investigations of CW plasma multipliers are being made at 8 mm with powers up to 30 w and at3 cm with powers up to 300 w. Numerous, sharp resonances in a plasma resonator consisting of a gyromagnetic plasma column between two parallel metal plates with magnetic fields up to 4,000 gauss were observed. Difficulties in determining all the parameters of the system, in particular the plasma density, have hampered effonts in correlating the observed and calculated data. A Doppler-Helitron idea using a dielectric cavity resonator is being considered. By employing the Doppler effect, an attempt is being made to see if the effective cyclotron frequency can be substantially reduced thereby avoiding the problera of 100 to 1,000 kilogauss magnetic fields.
