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. WebNov 1, 2024 · The ICRF system on EAST consists of 8 transmission networks. RF power (34 MHz for power lines 1–4 and 35 MHz for power lines 5–8) is delivered through coaxial lines with the characteristic impedance of 50 ohm. The power is measured by directional couplers near transmitters. WebThe performance of ICRF heating has progressed steadily in the EAST. Initial ICRF experiments started in 2010 [41, 42].
