ABSTRACT:
A gyrotron providing first and second microwave frequencies comprises a dual frequency cavity coupled between an electron gun and a waveguide. The electron gun, the dual frequency cavity and a segment of the waveguide are surrounded by a variable magnetic source having first and second operating states. The first state provides microwaves at the first frequency, while the second state produces microwaves at the second frequency.
