Abstract:

A device for sealing a vacuum chamber is described, the vacuum chamber providing a first volume. The device includes an intermediate volume providing a fluid communication between the first volume and a second volume, a first seal for sealing a first conduit associated with the first volume and sealing the first volume from the intermediate volume, a second seal for sealing a second conduit associated with the second volume and sealing the second volume from the intermediate volume, and a third conduit providing a first fluid path to the intermediate volume.
