Recent progress made in the prediction, characterisation, and mitigation of multipactor
discharge is reviewed for single‐and two‐surface geometries. First, an overview of basic …

A shape-memory polyurethane (SMPU) was designed and used in the field of self-healing
coating due to the capability to recover to its permanent shape in a predefined way. This …

Electron cloud mitigation is an essential requirement for high-intensity proton circular
accelerators. Among other solutions, laser engineered surface structures (LESS) present the …

This work seeks to understand how the topography of a surface can be engineered to
control secondary electron emission (SEE) for multipactor suppression. Two unique, semi …

A novel compact and highly efficient dual-polarized horn-like antenna is presented. It
exploits a radiating aperture that is fed by four smaller waveguides via a quad-furcated …

Two-surface multipactor with a Gaussian-type waveform of rf electric fields is investigated by
employing Monte Carlo simulations and 3D electromagnetic particle-in-cell simulations. The …

With the development of industrial civilization, advanced manufacturing technology has
attracted widespread concern, including in the aerospace industry. In this paper, we report …

Abstract Porous Ag/TiO2/Au coatings with excellent multipactor suppression were prepared
by fabrication of porous Ag surface through two-step wet chemical etching, synthesis of TiO2 …

Suppression of the total secondary electron yield (TEY) of metal surfaces is important in
many areas such as accelerator, satellite, and Hall thruster. Among TEY suppression …

High power microwave devices have been suffering from secondary electron yield (SEY),
which occurs at the surface and leads to increases in energy dissipate and noise level in …
