The University of Texas at Austin is constructing a new facility for the Center for Electromechanics at the expanded Balcones Research Center. The new facility will house a pulsed power supply consisting of six 10-MJ homopolar generators. The machines are presently being designed to be connected in various series and parallel combinations to match a wide range of loads - high current industrial processes, research in electromagnetic propulsion, generation of high magnetic fields in low impedance magnets, and testing of high current opening switches. A truncated drum-type homopolar generator configuration has been selected for the new installation based on the need for high energy transfer efficiency, a desired 2- to 5-min repetition rate, and minimum downtime for brush maintenance. Each generator is nominally rated to deliver 833 kA at a brush loading of 1,170 A/cm2 into either a resistive or an inductive load with a maximum open circut voltage of 110 V from a speed of 6100 rpm. When connected in parallel, the system will deliver more than 5.0 MA to the load, which is sufficient, for example, to pulse resistance weld a 645 cm2 iron section of steel pipe in less than one second.
