ICRH System for the Ignitor Experiment

An auxiliary ion cyclotron resonance heating system is included in the design of the Ignitor machine to provide a wider margin of success for ignition and to explore a variety of plasma regimes. Simulations with a full wave code, carried out for deuterium-tritium plasmas and wave frequency f=115 MHz, during the initial magnetic field and plasma current rise, show strong direct ion heating. A modular configuration of the ICRH system has been adopted, operating in the frequency range f=70-120 MHz. Two modules, based on 8 generators and 4 antennas, occupying 4 equatorial ports will be installed initially, with the possibility of adding two more antennas
