Research Abstract

A broadband continuous frequency tunable gyrotron was developed as power source for analysis of protein structures. Frequency tuning of about 4 GHz around 395 GHz was observed with output power greater than 50 W by changing the cavity magnetic field. The frequency also varied about 1 GHz as the anode–cathode voltage in a magnetron injection gun varied. Thus, the broadest tuning bandwidth in the 400 GHz band gyrotrons was achieved.
