Technical Details on Charybdis from the E93-038 ESAD

• Magnetic Field
  • Maximum central field of 1.9 T @ 900 A, for a B·dl of 2.6 T·m
  • E93-038 max B·dl of 2.15 T·m @ 590 A
• Dimensions
  • Charybdis weighs 38 tons.
  • The overall dimensions are approximately 1.5 m tall, 2.3 m wide, and 1.7 m long.
  • With a 8.25 in gap, the aperture is 8.25 in high × 0.56 m wide. The gap length is 1.22 m along z.
• Power supply / Cooling
  • Each of the magnet’s two coils has a resistance of about 0.51 Ω.
  • The magnet requires a series current of 450 A to achieve the maximum field of about 1.9 T. In practice, the magnet is wired in parallel (total resistance of about 0.255 Ω) for a maximum supply current of about 900 A and a maximum supply voltage of about 230 V.
  • The magnet was be operated at lower supply currents (typically less than ∼530 A).
    • These operating parameters are within the capability of the Hall C SOS-D1 power supply.
    • Charybdis is water-cooled, requiring 40 gpm at 160 psi.
