Prof. Chen is a plasma physicist with a career extending over 48 years and encompassing both experiment and theory. He has devoted about a decade each to the subfields of magnetic fusion, laser fusion, plasma diagnostics, basic plasma physics, and low-temperature plasma physics. Most plasma students are familiar with his textbook Introduction to Plasma Physics and Controlled Fusion. His current ...
