The objective of this program is to develop a microwave oscillator capable of producing 200 kW of CW power at 60 GHz. Output mode content of X-6 was measured and found to be a mix of TE/sub 01/, TE/sub 02/ and TE/sub 03/ modes with unsatisfactory mode purity. Measurements and calculations are reported which indicate that the mode conversion is caused primarily by collector diameter changes. Test results are reported for X-7 which used a 2.5-inch-diameter collector of extended length. Beam power densities are higher than desired. Preliminary analysis of mode conversion was done on a new 4-inch-diameter collector design. The results are quite promising.
