Abstract
A 140 GHz gyrotron capable of producing output powers up to 900 kW for 1000-second pulses has been developed at CPI. Factory testing demonstrated 1000-second operation at the 25 A CW current limit of the test facility, at which the output power was about 500 kW, and demonstrated 900 kW operation for short pulses. The gyrotron was then shipped to Hefei, China, and installed as part of the electron cyclotron heating and current drive system for the EAST tokamak. Commissioning of the gyrotron at the EAST site is currently in progress, with the goal of demonstrating operation at full parameters (900 kW for 1000-second pulses).
