| 摘要 |
The invention relates to a vacuum treatment chamber, comprising a coil arrangement for generating a magnetic field in the chamber, wherein the coil arrangement comprises at least one first coil section and a second coil section, wherein the first coil section and the second coil section are arranged adjacent to each other in cross-section and preferably in one plane, such that at least a partial section of the first coil substantially follows the course of a partial section of the second coil, wherein the spacing of the first partial section from the second partial section is at least one order of magnitude smaller than the cross-section of the optionally smaller coil section. |
