WebMar 15, 2010 · Preparations for the final power amplifier of the 1.5 MW RF source were discussed in the EAST ICRF heating system with a wide frequency range of 25 to 70 MHz. The wide-band, high-power, steady-state RF amplifier will be illustrated from three main aspects: the optimized operating parameters, input circuit, and output circuit. WebAug 13, 2009 · Introduction - Ion Cyclotron Range of Frequency (ICRF) waves are candidates for heating (ICRH), current drive, and possible flow drive in ITER and future tokamaks. There are considerable challenges developing the technology of ICRF systems and the tools for assessing effects on plasma performance.
