The primary theme of the WVU plasma physics group is space-relevant plasma physics. My group has a number of experimental laboratory, experimental space, and theoretical research projects. The core of our experimental laboratory plasma physics program is a high-density helicon plasma source coupled to a large space simulation chamber [Large Experiment on Instabilities and Anisotropies (LEIA)]. The WVU Hot hELIcon eXperiment (HELIX) source operates in a steady-state mode and is unique in that it can operate over a wide range of driving frequencies (0.3-35 MHz) and exhibits relatively high ion temperatures. The ion temperatures in argon and helium plasmas are measured with a non-invasive, laser induced fluorescence diagnostic. Current research projects include the investigation of Alfven wave reflection and nonlinear interactions in high beta plasmas, the study of spontaneously forming double layers in expanding plasmas, the study of slow waves in the edge of helicon sources, the development of new laser induced fluorescence schemes for argon and helium ions using tunable diode lasers, and the development of two-photon LIF schemes for the direct measurement of neutral hydrogen densities in fusion plasmas.

In collaboration with the Southwest Research Institute, Los Alamos National Laboratory, University of Southern California, and MIT, we participated in the launch of the world's first transmission grating based neutral atom imager on the IMAGE spacecraft in March 2000. This instrument directly detected and imaged neutral atoms emitted from the Earth's magnetosphere. With a single image, a neutral-atom "camera" can provide a detailed picture of the spatial distribution of the plasma trapped in the Earth's magnetosphere. The IMAGE mission has now ended and we have moved on to the TWINS mission. TWINS consists of two similar neutral atom cameras, each on different spacecraft.
