The joint venture of the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University provides access to world-class diagnostics, computational tools, and expertise in plasma physics for characterizing low temperature plasmas (LTP) -- a rapidly expanding source of innovation in fields ranging from electronics to health care to space exploration.
