Five-Megajoule Homopolar Upgrade
The five-megajoule homopolar generator (5-MJ HPG) designed and built in 1974 by the Center for Electromechanics at the University of Texas at Austin (CEM-UT) was the result of an engineering feasibility study that examined ...
Power Supplies for Airborne Laser Systems
This paper investigates the power supply options for an airborne laser system (solid state laser diodes). The application demands a power supply capable of a high repetition rate (1,428 pulses per engagement over 2 s) and ...
Methods for Producing the Plasma Initiation Pulse in Ohmic Heating Circuits in Tokamak Power Reactors: Resistive Dissipation, Transient Inductive Storage, and Transient Capacitive Storage
The plasma initiation phase occurring at the beginning of the operating cycle of a tokamak has the role of transforming a weakly ionized high resistance gas into a low resistance plasma type discharge. A plasma initiation ...
System Engineering and Design of a Pulsed Homopolar Generator Power Supply for the Texas Experimental Tokamak
The design of a homopolar generator power supply for the Texas Experimental Tokamak (TEXT) is presented. Four series-connected disk type homopolar machines serve as inertial energy storage and conversion devices to supply ...
Investigation of the Homopolar Motor Generator as a Power Supply for Controlled Fusion Experiments
With the impending construction of large controlled fusion feasibility experiments, the need for reliable, inexpensive inertial energy storage to power the confinement magnetic field ls becoming more urgent. To investigate ...

Operating Modes for Compulsator Based Electromagnetic Launcher Systems
The compensated pulsed alternator (compulsator) is a versatile power supply capable of interfacing with the electromagnetic launcher in various ways. The method that has been explored at length with several systems is the ...
Circuit Analysis of the Use of Rectifying First Wall to Drive the Plasma Current During the Burn Period of a Tokamak Fusion Reactor
The possibility of driving a tokamak fusion reactor during the burn with a rectifying first wall and a steadily modulated or slightly decreasing Ohmic Heating (OH) current, is investigated. Computer based electric circuit ...
Applying a Compensated Pulsed Alternator to a Flashlamp Load for NOVA-Part II
The compensated pulsed alternator (compulsator) has been proposed as a possible alternative to capacitor banks for driving xenon flashlamps for pumping neodymium glass laser amplifiers for NOVA. An algorithm for sizing ...
