Abstract : To determine the performance and quench behavior of a large, fully-potted, NbTi superconductive magnet, a 0.61-m test coil has been constructed which contains heaters, thermocouples, and strain gauges installed at various winding locations. The magnet has an inductance of 49 henries, 7502 turns of copper stabilized NbTi wire, and a magnet load-line critical point of 190 amperes at 6.5 tesla. The methods and techniques used to construct the fiber glass reinforced, epoxy impregnated magnet are described. The results of the electrical and thermal measurements of the test coil behavior for quenches initiated at various winding locations and at operating currents of up to 150 amperes are presented. The laboratory measurements results are compared to the results obtained from the QUENCH computer program simulation of this magnet to assess the program's ability to describe the actual quench behavior of the magnet.
