Technical Details from the ESAD: The overall dimensions are approximately 1.5-m tall, 2.3-m wide, and 1.7-m long. Charybdis weighs 38 tons. 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. 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 will be operated at lower supply currents (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.
