In this paper we will present design studies for the collectors and collector sweeping systems of two different high power CW gyrotrons: a) The 1 MW 170 GHz cylindrical-cavity gyrotron for ITER (the backup solution for the 2 MW coaxial-cavity gyrotron), which should have the capability to be operated in modulated mode with a resulting total collector loading of up to 1.5 MW. b) A 4 MW 170 GHz coaxial-cavity...
It is desirable to increase the RF power per gyrotron tube for plasma heating in future fusion devices. The realization of gyrotrons with highest possible output power will reduce their overall number and superconducting magnets required for future fusion reactors. In this work the feasibility of a 4 MW 170 GHz coaxial-cavity gyrotron is investigated. A mode selection procedure is presented and proper...
A collaborative effort between European research Associations and Thales Electron Devices (TED) has been launched by the European Fusion Development Agreement (EFDA) in 2003, aiming at the development of an industrial 170 GHz/2 MW/CW coaxial cavity gyrotron. The first prototype is expected to reach 2 MW/1s and is presently being tested in Lausanne at a dedicated test facility. The test facility has...
A collaborative effort between European research associations and Thales Electron Devices (TED) has been launched by the European Fusion Development Agreement (EFDA) in 2003, aiming at the development of an industrial 170GHz/2MW/CW coaxial cavity gyrotron. The first prototype, although designed to be CW compatible is expected to reach 2MW/ls and is presently being tested in Lausanne on a specially...
