Notes on magnetic coil design

摘要

This brief report summarizes work done which addressed the issue of sizing the USTX Ohmic heating solenoid by imposing some physical constraints on the TF and OH coil designs. A computer code is used for this study. The TF coil sets the solenoid inner radius at 0.10 meters. Allowing a 2.5 cm gap between the inner plasma radius and outer radius of the solenoid fixes the latter at 0.185 meters. The OH solenoid radial thickness is then 0.085 meters. The plasma current obtainable is I(sub p) = 1.05 megamp.
