Development of a short-pulse, 2.5 MW transmitter operating at 120 MHz for high-magnetic field fusion plasmas is described and experimentally characterized. The transmitter discussed here can be comprised alternatively of a tetrode-based Driver, or a Solid-State-Amplifier (SSA), either of which then excites a tetrode-based Final Power Amplifier (FPA). The FPA is a modified 80 MHz, fixed frequency FMIT (Fusion Materials Irradiation Test) amplifier. Analyses and experimental modifications made to match and operate the transmitter at high power at 120 MHz are described. The final output cavity design was significantly reduced in size for the shorter wavelength and validated through high power operation with the actual tetrode. The experimental schematic, setup, and results of the Driver and FPA output power, gain, bandwidth, efficiency, and frequency range are discussed. Differences between the Driver and SSA exciting the FPA are identified. Future work is also considered. [ABSTRACT FROM AUTHOR] |
