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 efficiency emission (SEE) coefficient of the multipactor inhibiting carbon nanofilm is desirably less than a SEE coefficient of the underlying surface of the component.
Claims36
An RF, microwave, or millimeter wave energy device component that is exposed to RF energy in a vacuum environment, wherein the component includes:
- a multipactor-inhibiting carbon nanofilm covering the entire surface of the component that is exposed to the vacuum environment or covering a portion of the entire surface of the component that is exposed to the vacuum environment, wherein a secondary electron emission (SEE) coefficient of the multipactor-inhibiting carbon nanofilm is less than a SEE coefficient of the underlying surface of the component.
An RF window, comprising:
- a plate of material transparent to electromagnetic energy across one band;
- and a carbon nanofilm layer on at least one surface of the plate in a thickness so as to reduce the transmission of electromagnetic energy through the RF window at another band.
A multilayer RF window, comprising:
- a material transparent to electromagnetic energy across one band;
- a carbon nanofilm layer disposed on at least one surface of the material in a thickness so as to reduce the transmission of electromagnetic energy through the RF window at a second band;
- and a third layer that inhibits the transmission of electromagnetic energy across a third band.
