| 摘要 |
A thermally stable magnetic deflection assembly for use in an electron or particle beam machine with several separately potted magnetic coils spaced apart and arranged in a particular vertical position on a central pipe. Non metallic, low coefficient of thermal expansion, highly thermally conductive materials are used throughout and means are provided for maintaining the entire assembly at a desired temperature. Also disclosed is a method of making a thermally stable magnetic deflection assembly.
