Control of Imploding Metal Liners

This project will help the industrial partner design tests to prove a concept for fusion energy production. In the tests, metal cylinders (and other shaped liners) are dynamically collapsed to compress a high temperature plasma to fusion conditions. This highly dynamic event, however, may result in some of the metal from the cylinder contaminating the plasma. A strong shock wave can result in material leaving the wall of the cylinder, or the impact of one metal surface on another can result in jetting of metal. The metal liner can also buckle or rupture.

Magnetic Compression and Stability of Spheromaks

The objective of a fusion device is to confine a plasma and heat it to a temperative high enough for its ions to gain sufficient energy to overcome their mutually repulsive force and fuse. Fusion neutrons will provide a heat souce that's used to generate electricity in a steam cycle. Fusion power is environmentally friendly and the fuel source is abundant. A spheromak is a toroidal plasma configuration that has internal currents to maintain the magnetic field that keeps it together. Several methods are used to compress spheromaks at General Fusion.

Numerical Simulation of Fluid-Structure Interaction in Liquid Metals

General Fusion is currently working to develop a relatively small, low-cost fusion reactor; work has reached the proof-of-concept stage. The reactor consists of an enclosure filled with molten lead, spun about one axis to create a plasma-filled cavity. A mechanically-induced shock wave travels radially inwards, focusing as it propagates and collapses the plasma cavity. This collapse heats and pressurizes the plasma and initiates a fusion reaction that releases energy, re-expanding the cavity and causing another shock to propagate radially outwards through the lead.
