Abstract :
A 140 GHz gyrotron capable of producing output powers up to 900 kW for 1000 second pulse durations has recently been developed and demonstrated at CPI. In July of 2014, the gyrotron was shipped to Hefei, China for use in the electron cyclotron heating and current drive (ECH&CD) system at the EAST tokamak. Installation of the gyrotron at EAST is complete and initial operation is underway. Design features of the gyrotron, results of the experimental demonstration at CPI, and the status of demonstrations in China will be discussed.
