| Abstract: | The first of four Varian 500 kW 110 GHz gyrotrons (VGT-8011) to be used in the new 2 MW 110 GHz electron cyclotron heating system being developed for the DIII-D tokamak was put into test at General Atomics within the last year. This gryotron has been used to demonstrate the overall system efficiency and to validate the design of individual transmission line components. The first plasma heating observed with a 110 GHz was consistent with the power expected for the greater than 85% transmission efficiency of HE{sub 1,1} power. A comparison of the General Atomics̀ TE{sub 15,2} to HE{sub 1,1} mode converter with the Vlasov-type mode convertor designed by the University of Wisconsin showed similar conversion efficient. The overall ECH system performance during the first year of testing will also be discussed. |
