Performance analysis of conduction cooled HTS based magnet coil

Development of cryocooler technology makes it possible to have conduction cooled superconducting magnet system. We have designed and fabricate a laboratory-scale conduction -cooledpancake type High Temperature Superconducting (HTS) magnet at VECC. Kolkata. It consists of fifteen number of double pancake coils each inserted between copper plates which is mounted on a cold-plate made of OFHC copper and thermally connected with the cold head of the cryocooler. Each pancake coil is individually tested at liquid nitrogen temperature prior to assembly. The magnet is successfully cooled, energized and carried out different performance tests. The paper describes the results of measurement and its performance has been analyzed to enhance the magnetic field.
