Abstract
A vacuum system is described. The vacuum system includes a vacuum cell and an ion trap. The vacuum cell includes walls having an inner surface that form at least a portion of a vacuum chamber. At least a portion of the inner surface has a topography including structures therein. The structures include a getter material. The ion trap is within the vacuum chamber.
Claims18
A vacuum system, comprising:
- a vacuum cell including a plurality of walls having an inner surface forming at least a portion of a vacuum chamber, at least a portion of the inner surface having a topography including a plurality of structures thereon, the plurality of structures including a getter material;
- an ion trap within the vacuum chamber;
- at least one additional getter including a plurality of getter pieces;
- and
- an encapsulant configured to retain the at least one additional getter and having a plurality of perforations therein, the getter pieces being larger than the plurality of perforations.

A vacuum cell, comprising:
- a first portion of the vacuum cell including a getter material and having an aperture therein, the first portion having an inner surface forming a first portion of a vacuum chamber, at least a portion of the inner surface having a topography including a plurality of structures formed thereon, the plurality of structures including a first portion of the getter material, a second portion of the getter material having a vacuum-prepared gettering surface;
- a viewport configured to provide optical access to the vacuum chamber and hermetically sealing the aperture, being fused to the first portion of the vacuum cell, wherein the viewport is bonded to the first portion such that the viewport is fused to the vacuum cell, the viewport having an average surface roughness of not more than 1.5 micro inches;
- and
- a second portion of the vacuum cell forming a second portion of the vacuum chamber, the second portion including an ion trap and a substrate hermetically sealed to the first portion of the vacuum cell.

A method for providing a vacuum system, comprising:
- providing a vacuum cell including a plurality of walls having an inner surface forming at least a portion of a vacuum chamber, the providing the vacuum cell further including
- forming a topography including a plurality of structures in at least a portion of the inner surface, the plurality of structures including a getter material;
- providing an ion trap configured to reside within the vacuum chamber;
- providing, in the vacuum chamber, at least one additional getter including a plurality of getter pieces;
- and
- providing an encapsulant configured to retain the at least one additional getter and having a plurality of perforations therein, the getter pieces being larger than each of the plurality of perforations.
