Design and experiments of 65 T high field pulsed magnet

A 65 T pulsed magnet has been manufactured and tested. The magnet coil consists of 14 layers of pure copper. Each layer of copper wire is reinforced with a layer of Zylon fiber composite. The thickness of the Zylon layer in the inner section is optimized so that the stress is even. In order to balance energy distribution and avoid overheating, two different cross-section copper wires are used in the inner and outer sections, respectively. The coil is 120 mm long with a bore of 12 mm diameter. Its power is supplied via a 1 MJ/32 mF/25 kV high density capacitor bank. At 20.6 kV voltage, 65 T field with a pulse duration of 20 ms was obtained.
