Abstract
Certain embodiments described herein are directed to couplers that can be used to provide a seal between a source assembly and a vacuum chamber. In certain examples, the seal can be provided upon movement of a moveable component of the coupler. In some examples, rotation of the moveable component is operative to provide an axial force to a stationary component coupled to the moveable component such that the stationary component is biased to provide a suitable seal to the vacuum chamber.
Claims26
A source assembly comprising:
- a moveable component configured to provide an axial force upon movement in a first direction and release the axial force upon movement in a second direction;
- and
- a stationary component coupled to the moveable component and configured to receive the axial force from the moveable component, the stationary component comprising a source coupled to a vacuum port, the vacuum port configured to provide a substantially fluid tight seal at a sealing face of a vacuum chamber in a device upon the provision of the axial force from the moveable component.
A source assembly comprising a coupler configured to couple the source assembly to an instrument housing to provide a substantially fluid tight seal between the source assembly and a vacuum chamber in the instrument housing upon coupling of the source assembly to the instrument housing and movement of the coupled coupler.
