 Cosmic Ray Electron Synchrotron Telescope in Antarctica

The lecture, which is intended for a general audience, will provide a guided tour of cosmic-ray research discoveries, including results from Mueller's Cosmic Ray Nuclei experiment on the Space Shuttle. The event is among those sponsored by the Penn State Institute for Gravitation and the Cosmos during 2012 to mark 100 years of cosmic-ray research and discoveries.

Over the span of a long and distinguished career, Mueller has introduced new techniques for the detection of energetic cosmic particles, and has made definitive measurements of antimatter particles and energetic nuclei and electrons. He has been the principal investigator for numerous experiments with instruments tethered to balloons that fly 120,000 feet up to the outer edge of Earth's atmosphere, where they measure the cosmic rays from powerful explosions in space. A close colleague of Penn State physicists for many years, he now is collaborating with them on the Cosmic Ray Electron Synchrotron Telescope (CREST) instrument, which flew for the first time in December 2011 and landed in January 2012 with new cosmic-ray clues that Mueller and his Penn State colleagues now are analyzing.
