Description

The authors demonstrated a conduction cooled (Nb,Ti)3Sn superconducting magnet system without liquid helium. The magnet system is mainly composed of (Nb,Ti)3Sn superconducting coil, high-Tc oxide current leads, a GM cryocooler and a cryostat. The (Nb,Ti)3Sn superconducting coil cooled by the second stage of the cryocooler is operated at 11 K in vacuum. The cylindrical (Bi,Pb)2Sr2Ca2Cu3 oxide current leads were cooled below 77 K by the cryocooler. This system generates a magnetic field of 4.6 T in a 38 mm room temperature bore at the operating current of 465 A. 2 hours holding at the operating current of 400 A were performed
