Two ITER gyrotrons was manufactured and these short-pulse tests were completed. Similar beam profiles were identified and 1 MW power was achieved for both #1 and #2 ITER gyrotrons. The long-pulse tests of these gyrotrons are underway and at the present 0.2 MW CW-operation for 300 s has been obtained. The output power of 1 MW with and total efficiency of 48 % was also performed for pulse duration of 10 s., Nineteenth International Vacuum Electronics Conference (IVEC 2018)}, title = {Progress on Performance Test of ITER Gyrotron}, year = {2018} }
