Development of high energy pulsed plasma simulator for plasma-lithium trench experiment
… lithium infused trench (LiMIT) device, a pulsed plasma source utilizing a theta pinch in conjunction with a coaxial plasma accelerator has been developed. An overall objective of the project is to develop a compact device that can produce 100 MW/m2 to 1 GW/m2 of plasma heat flux (a typical heat …

Axial Evolution of a Sheared-Flow-Stabilized Z Pinch
… 50-cm-long Z pinches formed from plasma accelerated through coaxial electrodes. The Z pinches are sustained between a nose cone at the tip of the plasma gun and an end wall at the end of the assembly region flux conserver. The end wall geometry is modified from a central hole to a …

Development of a MeVVA based beryllium-7 plasma source
We have designed a new type of plasma gun ion source for a Malmberg-Penning trap based on Metal Vapor Vacuum Arc (MeVVA) ion source designs. Our primary intent with this MeVVA-type source is to create a confinable beryllium-7 (7-Be) plasma. 7-Be is a peculiar isotope due to its varying radioactive …

Studies on the dynamics of limited filaments
… a diagnostic, conductive limiter is presented. Plasma filaments are coherent structures present in many fusion devices and transport a significant amount of particles and energy to vacuum chamber walls. The theories of filament propagation are based on a circuit model of current closure loops …

Experimental studies of magnetic reconnection in 3D geometries
… reconnection is an important and prevalent plasma physics phenomenon occurring in astrophysical (solar flares), space (magnetospheric substorms), and laboratory settings (tokamak sawtooth oscillations). It allows for a change in the magnetic field topology in plasmas while also transferring …

Graphene Oxide Reinforcement in Plasma Sprayed Nickel-5%Aluminum Coatings
<p>Metallic plasma sprayed coatings are widely used in the aerospace industry for repair on worn engine components. However, the inherent defects in these coatings limit the variety of repairs and reduce the service life of the repaired parts. A potential solution to overcome this problem is to mix …

Design and Characterization of a Coaxial Plasma Railgun for Jet Collision Experiments
Plasma railguns are electromagnetic accelerators used to produce controlled high velocity plasma jets. This thesis discusses the design and characterization of a small coaxial plasma railgun intended to accelerate argon-helium plasma jets. The railgun will be used for the study of plasma shocks in …
