Abstract
A high power gyrotron with a built-in a-cut Vlasov-type mode converter was experimentally studied. The cavity was designed to operate in the TE12,2 mode at 120 GHz. A converted wave of a linearly polarized mode was focused near the output port by using reflectors. The output wave obtained in the test had a circular power profile of 28 mm diameter (FWHM) and had a maximum power of 548 kW with an efficiency of 30.4 Z.
