N2 - A new-type of magnet system using high-Tc superconducting bulks has been developed, in which two aligned bulk disks are cooled down from the side face by thermal conduction and are magnetized along the c-axis in turn employing a split-type pulse coil. The temperature rise ΔT due to the magnetic flux intrusion is relatively small and the trapped field B TP is enhanced in comparison with the conventional bulk magnet system based on a solenoid-type pulse coil. BTP = 3.20 T on the SmBaCuO bulk surface at 50 K and BT4mm = 1.97 T on the vacuum sheath, 4 mm above the bulk surface, have been attained. This type of magnet system, consisting of multi-bulks, with usable surfaces on both sides in open space, can be realized only by use of a split-type pulse coil and has a potential for new application fields.
