Abstract

The Compact Toroidal Hybrid (CTH) is a new fusion design, combining the features of the stellarator and tokamak fusion concepts. The CTH contains seven independently powered coils that produce its magnetic field. There is a strong coupling between these coil systems due to mutual inductance. The most problematic coupling involves the helical field and ohmic heating coil systems. This coupling causes strong induced currents and voltages. Induced voltages are undesirable, since the helical field system provides one of the main sources of magnetic confinement for the CTH. The goal of this thesis was to study the helical field and ohmic heating coil systems in greater detail. I built a small model of these coils and studied their characteristics. I measured their self inductances with a variety of different methods, I measured the mutual inductance between the two coil systems, and I measured and graphically represented the magnetic field of the helical field coil system. This project involves both theoretical and experimental aspects of the problem studied.
