Gamma ray
TUNL operates three laboratory facilities, all of which reside on Duke University's campus. Two of the facilities, the Tandem Accelerator Laboratory and the Laboratory for Experimental Nuclear Astrophysics, are low energy charged beam accelerators. The third facility is the High Intensity Gamma-Ray Source (HIGS), which produces the highest intensity polarized Gamma ray beams in the world. TUNL is also involved in off-site research projects, including the Majorana Demonstrator Experiment, an ongoing Double beta decay experiment at the Sanford Underground Research Facility in Lead, South Dakota.
