Abstract

There is high demand for tunable X-ray undulators in modern synchrotron light sources. While PrFeB based magnets are most suitable for cryogenically operated permanent magnet undulators (CPMU), there are no development efforts or a manufacturing base for PrFeB magnets. We will develop PrFeB based magnets of higher remanence and better coercivity (at 77 K) than current neodymium based magnets for cryogenic permanent magnet undulators by researching new compositions and innovative processing approaches. At the end of the SBIR project, a United States manufacturing base for producing these magnets for CPMU applications will also be established. Commercial Applications and Other Benefits: The project will yield PrFeB based magnets for DOE applications and will also exploit their high temperature performance to benefit commercial applications such as electric motors.
