Dr. Earl Marmar received his Ph.D. in Physics from Princeton University in 1977. During his graduate research at Princeton, he helped to develop a technique to introduce an intense beam of low energy neutral atoms into the edge of a tokamak plasma discharge that has found subsequent application in fusion related experiments worldwide. In the late 1970s, working on the Alcator A tokamak at MIT, Dr. Marmar was the co-discoverer of the edge plasma radiative condensation phenomenon which has come to be known as the MARFE. From 1984-87, Dr. Marmar's research on Alcator C included the first unambiguous observations of charge transfer, from excited neutral hydrogen to highly stripped impurity ions in a tokamak plasma, and the lamb shift in the ground state of hydrogen-like argon was measured with unprecedented precision. In his experiments on Alcator C-Mod, he concentrates on studies of impurity and energy transport, particularly in enhanced energy confinement regimes which combine high pressure core plasmas with low impurity particle confinement.
