Conventional high-field pulsed magnets employ layered reinforcement techniques, where high-strength fiber composites are inserted around each conductor layer within solenoid coils to withstand the substantial Lorentz forces. For magnets exceeding 80 T, the required reinforcement layer thickness exceeds 5 mm. However, this design reduces the conductor filling factor and increases the coil...
Pulsed magnets in the US National High Magnetic Field Laboratory (MagLab) use rectangular cross-section conductors that reinforced by Nb-fibers. During the manufacture of the conductors, large deformation strain was required, leading to very high internal stresses. The internal stresses affected deformation behavior of the conductors. This special deformation behavior was reflected in...
Accelerating the cooling rate of pulsed magnets has a significant impact on the efficiency of physics experiments. Inserting axial liquid nitrogen cooling channels in the magnet is a common method to accelerate the cooling rate. However, the cooling channels prevent stress from being transmitted between the layers of the magnet, which reduces the structural strength and increases the design...
Copper-based conductive wires with both a high strength and a high electrical conductivity could find applications in aerospace and power engineering as well as in niche scientific applications such as materials for the production of high-field pulsed magnets. Indeed, in order to produce non-destructive fields, the coils must be wound of wires with a very high mechanical strength to resist...
