Force-Neutral Adjustable Phase Undulator

Synchrotron radiation and free-electron laser x-ray light sources, and the U.S. industrial radiation space, need compact and cost efficient undulators to continue to improve and expand radiation delivery to scientific and industrial users. The current state-of-the-art solutions are bulky, require complex kinematic systems and controls, and are costly to engineer and manufacture. Furthermore, U.S.-based industrial suppliers for undulators and related devices are scare, which leads to lengthy delays and higher costs. In response to this problem, RadiaBeam Technologies is proposing to engage in a technology transfer opportunity to advance undulator manufacturing by utilizing technology developed by Argonne National Laboratory, who has developed a next generation undulator dubbed the force- neutral adjustable phase undulator. This technology allows for high precision undulators to be more compact, cost-effective to fabricate and assemble, and straightforward to operate. The innovation is based on the inclusion of a secondary array of magnets, strategically placed and arranged to compensate the internal forces brought on by the main magnet array. In Phase I, RadiaBeam will develop a complete model of a 1-meter-long prototype, including detailed engineering, shimming methods, and address any necessary upgrades for the RadiaBeam magnetic measurement lab. The end deliverables of the Phase I project will be a complete set of design prints, a bill of materials ready for purchase, and a report detailing the manufacturing and assembly process, including validation. The work will enable RadiaBeam to become the premiere U.S. supplier of compact undulators. This project will provide an affordable and viable product that will serve the needs of Department of Energy radiation sources, while benefiting commercial sectors such as photolithography and medical imaging. The flexible and compact design allows for novel applications of undulators over a more extensive x-ray energy range.
