| titleOfInvention | Cesium beam tube |
| abstract | ABSTRACT OF THE DISCLOSURE An atomic beam tube provides a single sealed envelope structure that serves both as vacuum envelope and as structural member to which the operative components are attached. The envelope is composed of a heavy and relatively rigid frame and a relatively thin and flexible cover sealed to the frame. The operative elements are separately assembled in independ-ent subassembly units which are secured to the frame at a minimum of locations to provide fixed alignment and thermal isolation of the operative elements, and easy disassembly of the tube. The improved molecular beam tube apparatus provides a generally C-shaped permanent magnet having a curved inner surface and having an axis parallel with the directed beam. The permanent magnet provides a gap and further including two opposed reentrant portions extending inwardly of the inner surface. There are a first pair of pole pieces placed in the field of the permanent magnet within the gap and providing a deflecting field, and a second pair of pole pieces placed between the reentrant portions. An ion pump is located between the second pair of pole pieces, whereby said first pair of pole pieces is driven by the permanent magnet to provide a first state selector, and the second pair of pole pieces and the permanent magnet drive the ion pump in parallel with the first state selector. |
