NdFeb Halbach Magnet

Small Accelerator - Big Returns

Made from microcrystalline powders full of NdFeB microcrystalline grains. With high magnetic energy, special variety of magnetizing angles, and high precision, these magnets are assembled in a special array, used to focus and bend a high energy beam of electrons for the accelerator, which is the first energy recovery linear accelerator based on fixed field alternating gradient fields provided by the Halbach magnets.

This advanced particle accelerator design can reduce the cost and increase the versatility of facilities for physics research and cancer treatment. With this design, physicists could accelerate particles through multiple stages to higher and higher energies within a single ring of magnets, instead of requiring more than one ring to achieve these energies. In a medical setting, where the energy of particle beams determines how far they penetrate into the body, doctors could more easily deliver a range of energies to zap a tumor throughout its depth.

More than 25 scientists, engineers and technicians are collaborating on this design, started from year 2016, ran preliminary beam tests in year 2018, and are currently doing installation from summer of 2019, with expectation to test and complete project commissioning by the spring of 2020, and begin to explore the scientific applications of this new acceleration and energy-saving technique.

The properties of the permanent Halbach magnets match or even surpass those of electromagnets, which require much more precise engineering and machining to create each individual piece of metal. UMAG’s high energy & high precision & high standard magnets has provided best magnet solution for this special project.

Based on this successful experience of magnet solution, UMAG is committed to providing the best magnet solution for such project and new technology.
