Abstract

This paper provides an overview of the basis of design of the high-power amplification for the Ion Cyclotron Heating system of the Divertor Tokamak Test facility. Notably, this system will be entirely based, for the first time, on solid-state technology, marking a significant milestone in the development of advanced fusion energy systems. The amplifier operates within a frequency range of 60–90 MHz, delivering MW-level power and supporting long pulse durations. The design specifications of amplifiers under different operating conditions, such as plasma experiments, wall cleaning, and conditioning are provided. By explaining the reasons behind the adoption of solid-state amplifiers, the paper highlights the role of solid-state technology in advancing fusion research.
