“…This arrangement, significantly more complicated than present day circuits, will present challenges to the tuning and matching circuitry and software algorithms, which will be described in the following. The eight transmitters [Kazarian et al 2011] are rated for 2.5 MW CW at a VSWR of 2 and 3MW at a VSWR of 1.5. Provision is made for increased power in an upgrade.…”

“…For the full-field ITER regime (B 0 = 5.3 T), the impurity absorption region is located HFS off-axis (r/a 0.35) if operating at f = 40 MHz [28]. ITER RF generators are foreseen to deliver RF power in the range f = 35 − 65 MHz [29]. A more central heating can be obtained if the ITER frequency range can be extended to include the operational frequency f ≈ 37 − 38 MHz.…”

A new ion cyclotron range of frequency scenario for bulk ion heating in deuterium-tritium plasmas: How to utilize intrinsic impurities in our favour Physics of Plasmas 22, 082511 (2015) Abstract. Launching electromagnetic waves in the ion cyclotron range of frequencies (ICRF) is an efficient method of plasma heating, actively employed in most of fusion machines. ICRF has a number of important supplementary applications, including the generation of high-energy ions. In this paper, we discuss a new set of three-ion ICRF scenarios and the prospect of their use as a dedicated tool for fast ion generation in tokamaks and stellarators. A distinct feature of these scenarios is a strong absorption efficiency possible at very low concentrations of resonant minority ions (∼ 1% or even below). Such concentration levels are typical for impurities contaminating fusion plasmas. An alternative ICRF scenario for maximizing the efficiency of bulk D-T ion heating is suggested for JET and ITER tokamaks, which is based on three-ion ICRF heating of intrinsic Beryllium impurities. a) Corresponding author: yevgen.kazakov@rma.ac.be

“…The 20 MW RF power delivered to the plasma by the IC H&CD system will be generated by 9 RF sources [6], similar to standard RF transmitters. Each RF source can deliver up to 2.5 MW RF power on VSWR = 2 (or 3 MW on VSWR = 1.5), CW, in a frequency range from 35 MHz to 65 MHz.…”
