The NRL (Naval Research Laboratory) Phase-Locked Gyrotron Oscillator Program for SDIO/IST

Abstract

This report is on the phase locked gyrotron oscillator program for SDIO/IST. The introduction summarizes the program as well as possible SDIO applications for high power phase locked microwave and millimeter wave sources. It considers the different possible architectures for a phased array for an SDIO mission. Section II summarizes results in theory. The main accomplishment was the development of a slow time scale code which examines phase locking in time varying situations. Section III summarizes the experimental design of the low power experiment which will examine phase locking in overmode cavities. Section IV summarizes the results of the slotted cavity experiments. The axial slots allow for mode control. With a slotted cavity, a gyrotron oscillator has reliably generated 35 MW at 35 GHz in a standing TE Sub 13 mode. Section V summarizes results on the VEBA driven free running oscillator. This experiment has succeeded in generating 200 MW at 35 GHz in a TE Sub 62 mode. Section VI discusses experimental design of the VEBA fundamental mode three cavity phase- locked oscillator at 35 GHz. This experiment is expected to produce phase-locked power at the 5 MW level. Section VII discusses the experimental results up to now on this experiment. Section VIII discusses the experimental design of the strongly coupled phase-locked oscillator experiment. Keywords: Large scale phased array; Amplifiers; Synchronization of coupled oscillators; Veba driven; Free running oscillators.
