A hybrid R&D magnet for future Phase Rotation Intense Secondary Meson (PRIS
M) 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 magn
etic field of 10.6T at 90A in a warm bore diameter of 40 mm. The inner HTS
coil was made by solenoid-winding technique without degradation of the BSCC
O tapes. The R&D magnet was successfully cooled bg using cyrocoolers, and w
as stably operated at the design central field and was tested up to the max
imum central field of 11.6T.
