The cathodes are available in either unbalanced or balanced forms, and the field strength can be customised for any specified application. All of the sources are designed to yield very high sputter rates and for most applications the targets are directly water cooled to ensure efficient heat removal. A range of standard cathode sizes is available in either circular or rectangular forms, but any size can be manufactured and cathodes can be retro-fitted into existing machines. Modifications to the magnetic arrangement have resulted in significant improvements to the uniformity of deposition over the length of rectangular magnetrons. The magnetic assembly is easily removed from the magnetron body so that different assemblies can be supplied with each magnetron enabling deposition conditions to be optimised for different types of deposition and different types of target.
All sources can be flange or internally mounted.
Cylindrical magnetrons for coating internal surfaces Cylindrical magnetrons are now available down to a diameter of 40mm. These produce uniform erosion of the cylindrical target and are suitable for deposition on the internal surfaces of cylinders of about 75mm in diameter. 8 metre telescope mirrors Magnetron cathodes - technical information. In addition to the standard range of magnetrons, Teer Coatings Ltd offer a full custom design and manufacturing service.
