Abstract
The magnetic flux surfaces of the Compact Auburn Torsatron have been experimentally mapped in a variety of magnetic configurations. The magnetic surface mapping was done using the phosphor screen technique. The results are compared with an extensive computer model in order to validate the design coil structure and determine what modifications are needed to correct any minor winding errors. In initial field mapping experiments, a large up–down asymmetry was identified in the vacuum magnetic surfaces. A set of mapping studies was used to characterize the error through addition of terms to the coil winding law. The error was corrected with the use of a radial trim coil.
