Those applications that require higher magnetic fields than available with our standard soleniods (greater than 9 Tesla), and cannot be pumped to achieve a lower helium bath temperature, may require a magnet constructed with Niobium-Tin (Nb3Sn) material. Nb3Sn windings produce magnetic fields from

10 Tesla to more than 15 Tesla at 4.2K. AMI high field magnets consist of an Nb3Sn inner coil

(high field region) surrounded by an NbTi outer coil (background field).Standard AMI high field solenoids are listed below. Nonstandard high field solenoids can be custom designed upon request. The model numbers for high field solenoids use the same convention as standard solenoids.
