Abstract

For pt.1 see ibid., vol.27, no.2, p.490-502 (1999). This part describes the basic mechanical design of the two-stage collector, including the thermal performance. The design should be applicable to Gaussian mode gyrotrons over a very broad frequency range at power levels up to one megawatt CW. The design avoids large ceramic insulators between collector stages. Part II also describes an innovative regenerative power supply system that utilizes highly efficient, solid state switching technology that provides high reliability and significantly reduced cost over conventional technology. An advanced computer control system that will provide user-friendly gyrotron operation and allow modes of operation not possible with manual operation is also being developed
