Plasma Surface Interactions – Scientific Discovery through Advanced Computing (PSI-DAC)

As part of the “Plasma Surface Interactions: Bridging from the Surface to the Micron Frontier through Leadership Class Computing” SciDAC project, we are working to better understand how plasma facing components (PFCs) behave in a fusion reactor. At CPMI, we are investingating processes like sputtering, re-deposition and surface roughness evolution of materials with binary collision […]

Lithium Injector

Study of liquid lithium has increased as of late for its applicability in fusion energy. Liquid lithium implemented in the divertor of a fusion device may prove to be the path to a fusion device that produces significantly more energy than it consumes. Liquid lithium benefits a fusion device by gettering cold hydrogenic species at […]

Materials Characterization Test Stand (MCATS)

Liquid metals have received increased attention within the fusion community as of late. Liquid lithium, especially, has been the target of much interest for its ability to getter impurities and cold hydrogenic species at the walls of fusion devices. Lithium has been shown in several fusion devices to increase energy confinement times and to reduce […]

Seebeck Apparatus

Exposure to very large heat fluxes as well as large radiation loads inducing strong wear threatens to limit the lifetime of solid plasma facing component materials in fusion energy devices. Liquid metal devices, however, do not suffer the same ill effects. Liquid lithium, in particular, has shown promise as a potential candidate for a plasma […]

Special Projects

In order to get undergraduate and even high school students interested in plasma science, the CPMI often gives tours to highlight our research projects. As part of these tours, plasma demonstrations are shown so that students get a better understanding of the power of plasma!  

Solid/Liquid Lithium Divertor Experiment (SLiDE)

Originally completed in May of 2009, the Solid/liquid lithium divertor experiment (SLiDE) was designed with intention of studying surface tension driven flows in fusion relevant magnetic fields and conditions which would be applicable to divertors and limiters. The work was spurred on by the findings from the Current Drive Experiment-Upgrade (CDX-U) which is housed at […]

LAPCAP-Laser Assisted Plasma Coating at Atmospheric Pressure

The basic principle of Laser Assisted Plasma Coating at Atmospheric Pressure (LAPCAP) is to utilize a pulsed ND:YAG laser (t= 5~10 ns, with the intensity of 10^10~10^11 W/cm^2) to knock the atomic particles from the target and feed into the inductively coupled low temperature RF or microwave atmopheric plasma to further increase the efficiency of […]

DEVeX – Divertor Edge and Vapor shielding eXperiment

The plasma facing components in fusion reactors are subject to a number of high flux/high energy events during normal operation of the device. The Divertor Edge and Vapor shielding eXperiment (DEVeX) was developed to produce a pulsed, high density, high temperature plasmas capable of simulating the conditions in events such as type I Edge Localized […]

IIAX – The Ion-surface InterAction eXperiment

Crucial to the understanding of plasma material interactions is the interaction of ions with surfaces. Acceleration of ions through the plasma sheath, as well as bombardment from high energy ions heated within the bulk plasma contributes heavily to the modification of surfaces exposed to plasma, particularly high energy plasmas, such as those seen in fusion. […]

SLIP – Study of Lithium Infusion in Porous media

Innovative materials are created every year as candidates for fusion first-walls and the like. One such material is a porous molybdenum foam specifically proposed to hold a volume of liquid lithium within a fusion experiment. The SLIP experiment was created to examine the wetting behavior of this foam. Its follow-up experiment, SLIP2X, is a plasma […]
