My research is defined by a specific application: development of a suitable fuel for nuclear fusion, specifically, inertial confinement fusion. This effort requires research in several technical disciplines: vapor deposition and microfluidics, technologies that are used to make polymer capsules that contain the fusion fuel; and cryogenics and condensed matter physics, to study the crystal-growth mechanism, structure and properties of the deuterium-tritium fusion fuel. An emphasis of this research is to scale current technologies for mass production, to support an inertial fusion energy program. The most challenging aspect of this work is to determine how to deliver the cryogenic fuel, which is at a temperature of -255oC, into a reactor where the temperature will be over 5000oC, without affecting the fuel!
