Patent ID: 7425711

Claim:
A thermal control plate for incorporation in an anode assembly of an ion source, the thermal control plate comprising a disk with a top surface and a bottom surface, wherein the disk defines a gas duct positioned to interface with a gas port in a base assembly of the ion source adjacent to the bottom surface of the disk and further positioned to exit the top surface of the disk underneath a gas distributor adjacent to the top surface of the disk within the anode assembly; the disk defines at least two inner apertures positioned to interface with at least two fastening bolts that attach the gas distributor to the top surface of the thermal control plate; the disk defines at least two outer apertures positioned to interface with at least two inner bolts extending between a pole piece of the anode assembly and the bottom surface of the disk; and the disk defines at least one channel within the top surface traveling from the gas duct to a position radially outward of the gas duct.
