چکیده انگلیسی
To contribute to high performance long pulse (â¼65Â s) experiments in JT-60U, the target of the electron cyclotron (EC) operation in long pulse is 0.6Â MW for 30Â s with four gyrotrons, though 10Â MJ (2.8Â MW and 3.6Â s) was achieved in high power operation before 2003. One of the critical issues for the long pulse operation is detuning due to decay in beam current of the gyrotron. This decay comes from the cathode cooling by continuous electron emission. As a countermeasure for this issue, active adjustments for the heater current and anode voltage during the pulse have successfully extended the duration of a good oscillation condition for the gyrotron. As a result, 0.4Â MW for 16Â s with one gyrotron to the dummy load and for 8.7Â s to the plasma have been achieved up to now.
