Doctor of Philososphy [Ph.D] [Plasma Physics] From Princeton University

•  One example is fusion energy, for which the fuel is a high-temperature plasma. Low-temperature plasmas are used for a growing number of materials fabrication processes, including the formation of complex microscopic and nanoscopic patterns for microelectronic and micro-optical components, and the deposition of tribological, magnetic, optical, conducting, insulating, polymeric, and catalytic thin-films. Plasmas are also important for illumination, display technology, microwave generation, destruction of toxic wastes, lasers, spacecraft propulsion, astrophysics, and advanced-design accelerators for fundamental particle research.
• Applications of plasma science and technology meld several traditional scientific and engineering specialties. The purpose of this program is to provide strong interdisciplinary support and training for graduate students working in these areas. The scope of interest includes fundamental studies of the plasmas, their interaction with surfaces and surroundings, and the technologies associated with their applications.

Academics and Research

• The faculty responsible for the teaching program hold positions within the Department of Astrophysical Sciences. Recognizable on the list of faculty are many names associated with classic textbooks or research papers in the field of plasma physics. Students can pursue research with the teaching faculty, with associated faculty in other departments, or with any of the nearly one hundred scientists at PPPL. The Program in Plasma Physics emphasizes both basic physics and applications. There are opportunities for research projects in the physics of the very hot plasmas necessary for controlled fusion, as well as for projects in solar, magnetospheric and ionospheric physics, plasma processing, plasma devices, nonneutral plasmas, lasers, materials research, and in other emerging areas of plasma physics. With the field of fusion energy entering an exciting phase of burning plasma and technological implementation, increasing attention is paid to the practical engineering issues that will allow fusion reactors to become economically competitive.
• Graduate students entering the Plasma Physics Program at Princeton spend the first two years in classroom study, acquiring a foundation in the many disciplines that make up plasma physics: classical and quantum mechanics, electricity and magnetism, fluid dynamics, hydrodynamics, atomic physics, applied mathematics, statistical mechanics, and kinetic theory. Courses offered in the program are taught by the members of the Princeton Plasma Physics Laboratory's research staff who also comprise the plasma physics faculty. The curriculum is supplemented by courses offered in other departments of the University and by a student-run seminar series in which PPPL physicists share their expertise and graduate students present their research.
• In addition to formal class work, first- and second-year graduate students work directly with the research staff, have full access to laboratory and computer facilities, and learn firsthand the job of a research physicist. First-year students typically assist in experimental research areas, and second-year students usually undertake a theoretical research project. There are two exams that must be passed as a graduate student in the program, the physics department preliminary exam, usually in the first year, and the program's general examination, usually in the second year. After passing the general exam, students concentrate on the research and writing of a doctoral thesis.
