Assistant Professor Paul Hartman (Physics, Ph.D., 1938) was one of the first to investigate the use of X-rays generated as a byproduct of high-energy electron accelerators. This discovery goes on to inform the X-ray diffraction studies at facilities such as Cornell’s High-Energy Synchrotron Source (CHESS)
