Abstract
An undulator with a compact construction is provided that reduces weight, complexity and cost. The compact undulator system and methods provides mechanical integrity without compromising magnetic field quality.
Claims7
An undulator system, comprising:
- a rectangular box-shape frame formed by aluminum plates, the rectangular box-shape frame including an inside surface and an outside surface;
- a plurality of miniature linear bearings, wherein each of the miniature linear bearings is positioned within the inside surface of the rectangular box-shape frame;
- opposing magnet arrays, wherein each magnet array is fastened to one or more miniature linear bearings, wherein one magnet array is moveable along an axis horizontal to the rectangular box-shape frame and the other magnet array is fixed to the rectangular box-shape frame, each magnet array further comprises:
- a base plate, wherein the base plate is fastened to the one or more miniature linear bearings;
- a plurality of copper holders, wherein each copper holder of the plurality is secured to the base plate;
- and
- a plurality of permanent magnet blocks, wherein each permanent magnet block is soldered to each copper holder forming a gap between the opposing magnet arrays.
