Abstract
An apparatus includes a wall defining a boundary of an evacuated space and having a first side interior to the evacuated space and a second side exterior to the evacuated space, a first plate positioned on a first side of the wall and including a first magnet, a second plate positioned on a second side of the wall and including a second magnet, and a motor mechanically coupled to the second plate and configured to drive rotation of the second plate. The second magnet exerts an attractive force on the first magnet that causes rotation of the first plate in response to the rotation of the second plate.
Claims20
An apparatus, comprising:
- a wall defining a boundary of an evacuated space and comprising a first side interior to the evacuated space and a second side exterior to the evacuated space;
- a first plate positioned on a first side of the wall and comprising a first magnet;
- a second plate positioned on a second side of the wall and comprising a second magnet;
- and
- a motor mechanically coupled to the second plate and configured to drive rotation of the second plate;
- wherein the second magnet exerts an attractive force on the first magnet that causes rotation of the first plate in response to the rotation of the second plate.
A method, comprising:
- providing an ion beam incident on a target in a vacuum chamber;
- rotating the target by:
- driving rotation of an exterior plate outside the vacuum chamber, the exterior plate comprising an exterior magnet;
- and
- transferring the rotation of the exterior plate to an interior plate inside the vacuum chamber via an attractive force between the exterior magnet and an interior magnet of the interior plate, wherein the target is mounted on the interior plate.
