Several innovative applications of a travelling wave (combline) antenna designed for fast wave current drive have been demonstrated for the first time in the JFT-2M tokamak. High energy electrons of at least 10 keV were produced in the plasma core by

A low power ANT-Bosch fast ferrite tuner (FFT) was successfully tested into (1) the lumped circuit equivalent of an antenna strap with dynamic plasma loading, and (2) a plasma loaded antenna strap in DIII-D. When the FFT accessible mismatch range was

Nineteenth IEEE Symposium on Power Modulators.
Experimentally demonstrated and computer-simulated results with long-pulse and short-pulse modulators using solid dielectric capacitors are presented. These modulators have achieved matched load voltages greater than 600 kV and energies approaching 1

Nineteenth IEEE Symposium on Power Modulators.
The engineering design and predicted electrical performance of a 20-60 kW average power modulator system are presented. The system consists of a self-contained prime power subsystem feeding a 20 kW/ft/sup 3/ DC-DC power conditioner, which charges an

The DIII-D Advanced Tokamak Program requires the ability to modify the current density profile for extended time periods in order to achieve the improved plasma conditions now achieved with transient means. To support this requirement, DIII-D has jus

Observations are reported of the reproducible operation of an intense relativistic electron-beam-driven high-pulsed-power magnetron microwave tube at rep-rates of 1 Hz. These are the first observations of a reproducible rep-rate high-power magnetron,
