ABSTRACT
Abstract
Cadmium Zinc Telluride (CdZnTe) has been identified as an excellent gamma ray detector material. However, finding an economical way to grow large high quality crystals has been difficult. Using traveling heater method (THM) with a rotating and static magnetic field may be the solution. The rotating magnetic field could increase the growth rate and a static magnetic field less than 1.25 Tesla may reduce growth defects. The design and analysis of a 1.25 Tesla superconducting magnet cryostat system that surrounds the THM furnace with a rotating magnetic field is the focus of this thesis. Individual system components examined include the vacuum vessel, structural supports, current leads, and insulation. Total heat transfer from all of these components is determined and the operating temperature of the superconducting magnet is estimated. Finally, the instrumentation required to monitor the superconducting magnet state is discussed and the uncertainties in the measurement are approximated.
