428336, 428408, 20419234, 427140

Abstract:

In accordance with an embodiment of the invention, there is provided a coated graphite article. The article comprises graphite; and a conductive coating overlaying at least a portion of the graphite. The conductive coating comprises a through-thickness resistance of less than about 50 ohms as measured through the thickness of the graphite and the conductive coating. In accordance with another embodiment of the invention, there is provided a method for manufacturing a graphite article comprising a conductive coating. The method comprises treating graphite of the article with a reactive ion etch process; and after treating the graphite with the reactive ion etch process, applying the conductive coating over at least a portion of the graphite. In a further embodiment according to the invention, there is provided a method for refurbishing a graphite article comprising graphite and an overlaying conductive coating. The method comprises removing the overlaying conductive coating of the graphite article with a reactive ion etch process; and applying a new conductive coating over at least a portion of the graphite.

G21K 1/093
H05H 13/02

Abstract:

An example particle therapy system includes a gantry having a beamline structure configured to direct a particle beam that is monoenergetic from an output of a particle accelerator towards an irradiation target, where the beamline structure includes magnetic bending elements to bend the particle beam along a length of the beamline structure; and an energy degrader downstream of the beamline structure relative to the particle accelerator, where the energy degrader is configured and controllable to change an energy of the particle beam prior to at least part of the particle beam reaching the irradiation target.

Yan LIU - Lexington MA, US

International Classification:

H01L 21/683

Abstract:

Electrostatic chucks include multiple electrodes, each having a spiral shape surrounding a center of a surface of the electrostatic chuck, to provide a polyphase electrostatic chuck. Each electrode can be connected to a different phase of power. The spiral shapes can each avoid one another as well as avoiding holes or openings in the surface of the electrostatic chuck. The spiral shapes can be algorithmically determined using a processor. These electrostatic chucks can include three or more electrodes. Methods of manufacture of the electrostatic chucks include determining shapes for each of the electrodes and providing each of the electrodes.
