Abstract:
In this project, theoretical support was provided for the experiments at UC Davis aimed at the development of a zero-drive stable W-band gyrotron traveling-wave amplifier Gyro-TWT. The first of these tasks is the development of a fully relativistic theory for the interpretation of the test results of the most critical component of this gyro-TWT namely, a new type of electron gun based on the robust, long-lived, clean, low work function, high current density thermionic cathodes recently developed at UC Davis under the sponsorship of MURI-04. This is an electron gun to be used for the zero-drive stable Gyro-TWT. The second task was to design a novel W-band gyro-TWT, to yield over 100 kW with 5 bandwidth and 70 dB gain. The bandwidth is sufficiently wide for the generation of appropriately chirped pulses with pulse compression. Hence, it is suited for the ongoing upgrading of high-resolution space radars operated by Lincoln Laboratory, for which an array of 1-bandwidth sources is being planned due to the lack of a broadband source.
