Upgraded gyrotron components for enhanced thermomecanical performances

F4E, EGYC (European GYrotron Consortium) and Thales have designed two high performances gyrotron subsystems: a thermo-compensated cathode and an adaptative mini-channel cooling system. Theses components have been used to enhance the performances of a high-power gyrotron and are now available for new applications in vacuum tubes, particle accelerators or electronics.

Technology assets

• The upgraded cathode ensures isotropic thermomechanical deformation during high-energy demanding operations
• The adaptative mini-channel increases heat exchange while limiting thermo-mechanical stress and non-isotropic deformations
• The combination of these two components boosts gyrotron performance to achieve high power and efficiency
• The cathode is relevant for existing gyrotrons, vacuum tubes and particle accelerators. The mini-channel can increase cooling efficiency for CPUs or amplifiers.
