The Utah State University Materials Physics Group (MPG) performs state-of-the-art ground-based testing of space environment effects on aerospace materials. These include electrical charging and electron transport properties of both conducting and insulating materials; they emphasize studies of electron emission, conductivity, luminescence, and electrostatic discharge. Our research group consists of faculty, graduate, and undergraduate researchers. Publications and presentations are archived here.
