Experiments on Multipactor Suppression in a Coaxial Transmission Line

Multipactor discharges are capable of damaging and disrupting RF vacuum electronic devices. Developing new techniques for suppressing and preventing multipactor discharges is essential to ensure reliable, long-term operations. We explore two methods to prevent multipactor in a coaxial transmission line by altering the surface morphology. We evaluate the multipactor suppression properties of textured 3D printed versus porous conductor surfaces.
