Probing Cosmic Rays (IMAGE) University of Chicago Caption Scott Wakely, assistant professor in physics at the University of Chicago, and colleagues at Argonne National Laboratory built a prototype instrument for studying cosmic rays with unprecedented precision from a ground-based instrument. He and Simon Swordy, James Franck Professor in Physics at the University of Chicago, are developing a second-generation instrument for studying these phenomena, which have fascinated scientists for decades.
