Abstract—An 10T superconducting split magnet with a room-temperature bore of 40 mm was designed, manufactured and tested for X-ray diffractometer at The High Magnetic Field Laboratory in Hefei, China. The superconducting split magnet provides room-temperature splitting gap of 10 mm and scanning angle of 160 degrees for X-ray beam. As a result of magnetic field intensity considerations, the magnet is composed of a split-pair of Nb3Sn inner coils and NbTi outer coils. Nb3Sn coils and NbTi coils are connected in series separately and charged with two independent power supplies respectively. The magnetic field homogeneity is better than ±1% from -10 mm to 10 mm in axial direction. In addition, two pairs of HTS current leads and a two-stage GM cryocooler with cooling capacity of 1.5 W at 4.2 K were adopted to realize a zero liquid helium boil-off. In this paper, the magnetic design, manufacture, mechanical behavior analysis, and the test results of the magnet are presented.
