Inertial electrostatic confinement fusion (IECF) devices are utilized for studying nuclear fusion reactions, particularly for fusion neutron production. A strong electric field between two transparent electrodes results in the formation and acceleration of ions toward the device's center. The energy level of these accelerated ions reaches tens of kilo-electron volts, sufficient to produce fast neutrons through nuclear fusion reactions when deuterium gas is used. Overheating due to collisions of high-energy ions with the cathode surface is a primary issue that limits the applied power and long-term stable operation of these devices. In this research, an actively cooled cathode was designed and constructed for the IR-IECF device. Deionized recirculating water was used as the coolant to reduce the cathode temperature. The cathode, connected to a high voltage power supply via a feedthrough, can prevent high voltage breakdown and melting at input powers exceeding three kilowatts. Both theoretical and experimental results show excellent agreement in heat removal during continuous operation.
