Gyrotron Cathode Power Supplies for Fusion Research

USE CASE

Fusion research facilities rely on high-power microwave sources such as gyrotrons to heat plasma and support advanced experimental campaigns. Gyrotron cathodes require high-voltage DC power supplies capable of delivering stable, high-power output in demanding scientific environments.

Application context

In magnetic confinement fusion research, gyrotrons are used to generate high-frequency microwave power for plasma heating and current drive. Their cathode power supplies must combine high voltage, high power, electrical stability, safety functions and integration flexibility. For large facilities, scalability is also critical, as future systems may require higher power levels or modular architectures.
