75 Tesla Duplex Magnet

75 Tesla Duplex Magnet

Comprised of two coils, each powered by a different subsystem of the Pulsed Field Facility’s 4 MJ Cap bank, this magnet provides users with fields up to 75 tesla.

This capacitor bank-driven magnet provides users with 15% more field range than our standard 65 tesla magnets without the use of the 1.4 GW motor-generator. A modular design allows for full field pulses roughly every hour. Measurement techniques and probes used in the 65 tesla magnets are compatible with this system.



  • Maximum Field: 75 tesla
  • Bore Diameter: 9 mm He3 sample space (15 mm, 77 K bore)
  • Maximum Number of input and output leads possible:
    • 6 twisted pair (no rotation)
    • 4 coax (no rotation)
    • 4 twisted pair + 2 coax (rotation)
  • Pulse Duration: 80 ms
  • Rise Time: 1.8 ms from 30 T to 75 T
  • Maximum Rate of Field Change (dB/dt): 24 T/msec
  • Temperature Range: 500 mK – 300 K
  • Homogeneity: Homogeneity of 1% can be obtained within 20 mm from the center of this magnet.
  • Open for users who would pay for magnet time: Yes
