DESIGN AND PERFORMANCE OF PULSED-FIELD MAGNETS WITH AN OPTIMIZED ICE FIBER REINFORCEMENT

We present the design of a new magnet for the generation of non-destru ctive pulsed magnetic fields in the 50 T range. Basically, the new mag net combines the advantages of recently developed ice coils with optim ized fibre reinforced pulsed magnets. It consists of a stainless steel cylinder in which the coil is placed separately. The cylinder can be filled with water which leads to a strong reinforcement at 77 K. Sever al magnets of this type have been made and were tested. Furthermore, w e have tested the use of SiC-powder in combination with water. The inf luence of the resulting ceramics-like material on reinforcement and th ermal behaviour (cooling rate) is discussed.
