Activities are reported in a program to uncover ways in which a CW source of electromagnetic radiation can be developed for low millimeter and submillimeter wavelengths and to develop ways of using radiation as a diagnostic tool for plasma physics. The approach to the generation problem presently being followed is discusspd. Results of frequency conversion in plasmas include mixing a 0.1-watt 11-kmc signal with a 10-watt 9-kmc signal (used simultaneously to produce ard maintain the discharge) to obtain a 20-kmc sum frequency with a conversion ratio of approximately 29 db. Verification of the computed electromagnetic modes in a gyromagnetic plasma was obtained, and data are being obtained on the behavior mode as a function of system parameters. In research on generation of millimeter and submillimeter coherent electromagnetic radiation, it was experimentally established that second coherence of a beam in a dielectric tube waveguide, cannot take place if the length of the guide is less than the spacing of the bunches. A Doppler frequence shift scheme was analyzed which was designed to change the input 3-kmc power to 82.7 kmc. (For preceding period see TID-6997.) (J.R.D.)
