Abstract
A high power RF energy device component is disclosed that is exposed to high power RF energy in a vacuum environment, and includes a multipactor-inhibiting carbon nanofilm covering at least one surface of the component. A secondary electron emission (SEE) coefficient of the multipactor inhibiting carbon nanofilm is desirably less than a SEE coefficient of the underlying surface of the component.
