Title: Status and Development of Pulsed Magnets at the NHMFL Pulsed Field Facility

Abstract

The National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos National Laboratory is one of few research centers in the world that can create and use ultrahigh pulsed magnetic field for scientific research. The facility houses several types of nondestructive pulsed magnets which can provide the peak fields ranging from 60 to 100 T for users. This study will report the status of the user magnets and recent magnet developments to improve the quality and magnetic fields of our user magnets. In particular, this paper will present a new cooling technique that significantly reduces the cooling time without affecting the mechanical performance of the magnets. A possible upgrade of our facility with a new duplex magnet that is powered by a 4-MJ capacitor bank to deliver 80 T for users will be also reported. Finally, in addition, we will discuss some valuable lessons learned from magnet failures at our facility and possible further magnet design improvements to increase the magnet longevity or peak magnetic fields.
