TARGET CATHODE ASSEMBLY

摘要

The invention concerns a target cathode assembly with a target which produces an erosion trench during operation. Under the target support elements, are a cooling system and a magnetic system comprised of a return locking plate which is located on the side of the target cathode assembly opposite the target. The function of the invention is to avoid arc discharge on the target cathode assembly or between a neighboring assembly and target cathode assemblies. This is achieved by fitting the target cathode assembly with a soft magnetic material. Said material partially covers the exterior surface of the target cathode assembly during the exposure of the active target surface and is electrically connected to the target cathode assembly.
