Part of the research at Boise State is a miniaturized plasma propulsion thruster. The purpose of the thruster is to provide the necessary location realignments for small satellites in space. The grid creates an electrostatic field, which extracts plasma ions from an Inductively Coupled Plasma (ICP) source. The ions are propelled toward a collector plate being a second identical grid, which in turn creates the desired thrust. The size and density of the openings in the grid are essential to optimizing the thrust produced. The grid geometry contributes to the ion departure angle (focusing) and the ion transparency. The Stainless …

In order to further understand the fatigue and electrical properties of multifunctional magnetic shape memory alloys (MSMA), such as nickel-manganese-gallium (Ni-Mn-Ga), it is often necessary to modify existing machinery or design unique devices. The existing linear test apparatus has accomplished the goal of straining specimens by applying linear compression in a static magnetic field. The data acquired by this apparatus has been useful, but is limited by the device’s lack of magnetic field strength variability and closed loop control, as well as its data acquisition speed. The proposed study seeks to design and test a linear test apparatus that performs …
