Gyrotrons are fundamental to the operation of fusion energy devices. These high-power microwave systems generate millimetre-wave electromagnetic radiation, which is essential for heating and driving current in plasmas within Magnetic Confinement Fusion devices such as tokamaks and stellarators.
The development of gyrotrons dates back to the 1960s, with significant advancements over the decades. Initially developed in the Soviet Union, gyrotrons have evolved from the first high-power models in the 1970s to modern continuous wave (CW) gyrotrons capable of reaching power levels up to several megawatts. These innovations have made gyrotrons viable for contemporary fusion applications, such as those required in ITER and DEMO reactors.
Recently Alberto Leggieri was interviewed by Euro-Fusion News spotlighting the role of gyrotrons in emerging technologies. Access Article Here
