Design studies of a 460 GHz, 30–50 W, CW second harmonic gyrotron

摘要

In this paper, the design concept of a 460 GHz, 30–50 W, CW, second harmonic gyrotron for medical spectroscopy will be presented. Mode selection has been done keeping in view the second harmonic operation, first harmonic competitors, and a probable radial output system. Computation of starting currents has been carried out for the candidate mode considering all the competing modes. Design of the cold cavity resonator has also done. Interaction computations have been carried out for power and efficiencies.
