A high-power, rectangular discharge chamber is being designed by the University of Michigan for operation with multiple discharge cathode assemblies (DCAs). The multiple cathode approach attempts to increase thruster lifetime by operating three DCAs sequentially, possibly providing a threefold increase in discharge life. The baseline multiplecathode discharge chamber (MCDC) magnetic field topol...

Concerns dealing with the application of superparamagnetic ferrofluid as a drug carrier are studied both experimentally and theoretically. A dynamically controlled electromagnet experiment was designed to focus a stable ferrofluid trap at a specified distance. A theoretical magnetic driving force equation has been compared to experimental results for verification; verification was not achieved....
