A split superconducting magnet with large crossing warm bore of 150 and 50 mm is presented for material processing applications. Features of the magnet are characterized by a crossing warm bore and helium-free cryogenics. The magnet is configured in three pairs of split coils with pair separation of 85 mm to accommodate horizontal access. The magnet will be assembled after fabrications of two Nb3Sn and four NbTi coils. The maximum field in the inner Nb 3Sn coils exceeds 10 T when the center magnetic field is 8 T. Magnetic structures are optimized to acquire the maximum operation margin in a dynamic temperature range around liquid helium temperature. The quench protection of the magnet is analyzed in detail to release the 1.35-MJ magnetic energy safely. Finally, magnet cryogenics is presented and discussed.
