Abstract

A high-field HTSC conduction cooled magnet system is considered to be the most promising system for superconducting magnets of the next generation. The authors have been developing a 10 T Bi-2212/Ag solenoid magnet system with a room temperature bore of 50 mm. This system consists of inner, mid and outer coils. The coils are designed to generate 10 T at 10 K with Bi-2212/Ag ROSATwire (ROtation-Symmetric Arranged Tape-in-tube wire). This wire shows almost isotropic field dependence of J_c and ease of solenoid winding. The details of design of the system have been completed, and inner test coils and also a conduction cooling system have been built. Approximately a total of 3 km long Bi-2212/Ag ROSATwire has been employed for windings of the coils. In this paper, design of the magnet system, the preliminary results of trial operation of the inner coil and test result of the conduction cooling system are presented
