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.

First claim

The invention claimed is:

1. A method of fabricating a magnet array comprising the steps:
fastening a holder to a base plate;
soldering a magnetized permanent magnet to the holder, wherein the soldering step further comprises the steps of:
providing an arrangement of ferromagnetic material around the magnetized permanent magnet;
applying a high temperature process onto the magnetized permanent magnet; and
removing the arrangement of ferromagnetic material from around the magnetized permanent magnet.

2. The method of fabricating a magnet array according to claim 1 further comprising the step of attaching a cooling element to the base plate for controlling temperature of the magnet array.

3. The method of fabricating a magnet array according to claim 1 further comprising the step of moving by a driving mechanism the magnet array to control magnetic field strength of the undulator.

4. The method of fabricating a magnet array according to claim 1 wherein the holder comprises a copper material.

5. The method of fabricating a magnet array according to claim 1 wherein the magnetized permanent magnet is a neodymium magnet.

6. The method of fabricating a magnet array according to claim 1 wherein the providing step further comprises the step of arranging the ferromagnetic material to completely cover at least three sides of the magnetized permanent magnet.

7. The method of fabricating a magnet array according to claim 1 wherein the providing step further comprises the step of arranging the ferromagnetic material to form a top section, a side section and a bottom section.

8. The method of fabricating a magnet array according to claim 7 wherein the side section and the bottom section are made of a unitary body.

9. The method of fabricating a magnet array according to claim 7 wherein the top section, the side section and the bottom section are made of a unitary body.
