Abstract

Recent developments in high-power millimeter wave sources at the Naval Research Laboratory have led to an investigation of the use of these sources as atmospheric sensors. Two different sources have been developed, a quasioptical gyrotron and a TE13 mode gyrotron. The former is tunable from about 80 to 130 GHz and is capable of an average power in excess of 1 kW. Operation at the harmonic should also be possible but at reduced power. The latter is a fixed frequency source at 94 GHz and should easily be capable of average power in excess of 10 kW. The tunability of the quasi-optical gyrotron could be exploited to examine the absorption spectrum of gases with strong absorption lines in this region of tunability (for instance, ozone, CO, and N2O) and thereby determine their average concentration over long distances. The high average power of the cavity gyrotron could lend itself to a high power atmospheric sensor radar system.
