Abstract
A superconducting High Gradient Magnetic Separation (HGMS) sample test facility has been constructed at the IEE GAS. in order to shorten the magnet charging time, it is necessary not only to reduce the magnet i nductance, but also to increase the cryogenic stability. Based on our experience, narrow LHe channel cooling inside the high current density magnet is a good solution, In this paper, design, construction and te st results are described. The solenoid is wound with 1.46 mm x 2.4 mm and 1.26 mm x 2.4 mm rectangular NbTi-Cu composite, the filament diame ter is about 25 mu m, and the length, the inner and outer diameter are 420 mm, 176 mm and 232 mm, respectively. The channel between two laye rs is formed by 0.5 mm x 4 mm epoxy fibreglass strip along the axis. T he central field of 5.45 T has been reached and the charging speed of 9 T/min has been achieved.
