Abstract:

The overall objective of our research for ARO is to develop devices that have the potential for being compact generators of submillimeter-wave radiation. 1 The high-harmonic gyro-frequency multiplier, which is an efficient generator of high frequency rf, will be tested at the tenth-harmonic in our rebuilt test-stand. 2 High-power harmonic gyro-TWTs can be designed to operate in high order modes in large size waveguide by using the marginal stability design criterion. 3 Our high power, second-harmonic TE2 1 gyro-TWT, which is predicted to generate an order of magnitude higher power than state-of- the-art fundamental frequency gyrotrons, has been fully designed and construction is well underway. 4 The interaction strength in our high-harmonic CARM increases as the electron Larmor radius moves closer to the wall radius as the magnetic field is lowered towards a grazing intersection. 5 A high performance amplifier is predicted to result from our initial gyro-klystron experiment....
