Abstract :
A hybrid R&D magnet for future Phase Rotation Intense Secondary Meson (PRISM) beam project was designed and fabricated. The R&D solenoid magnet, which consists of an inner HTS coil and outer LTS coils, provides a central magnetic field of 10.6 T at 90 A in a warm bore diameter of 40 mm. The inner HTS coil was made by solenoid-winding technique without degradation of the BSCCO tapes. The R&D magnet was successfully cooled by using cryocoolers, and was stably operated at the design central field and was tested up to the maximum central field of 11.6 T
