Robert J. Goldston is a Professor of Astrophysics at Princeton University. He received his B.A. in Physics from Harvard University, and his Ph.D. in Astrophysics from Princeton University. He was director of the Princeton Plasma Physics Laboratory (PPPL), 1997 – 2009. He is Associated Faculty with the Program on Science and Global Security, and was acting director in Spring 2015. Goldston won the American Physical Society “Excellence in Plasma Physics” award in 1988 and chaired the American Physical Society Physics Policy Committee 2007–2009. He won the Fusion Power Associates Leadership Award in 2001, the Nuclear Fusion “Most Outstanding Paper” prize for 2012, and was named a “Leading Global Thinker” by Foreign Policy Magazine in 2014. He is a long-time U.S. representative on the ITER Science and Technology Advisory Committee. He serves on the board of the Council for a Livable World.
After participating in the development of the concept of a “Zero Knowledge Protocol” for warhead verification, Professor Goldston worked with MAE graduate student, Sébastien Philippe, on the successful demonstration of this protocol, using instrumentation located at the Princeton Plasma Physics Laboratory. He is currently working with MAE graduate student Mike Hepler on extending this technique to isotope discrimination, in particular between U-238 and U-235. This involves the construction of a new collimator/moderator to slow neutrons from 14.1 MeV to below 1 MeV. Goldston is also developing tools for use by international inspectors to verify that the operation of a uranium enrichment plant is within declared limits. He is collaborating with Los Alamos National Laboratory, where they are testing experimentally his idea for a non-invasive thermal method to measure the flow of uranium hexafluoride gas in pipes within uranium enrichment plants. This is a key means to determine if a plant is operating within declared limits. He is also constructing at PPPL a robotic neutron detector, which should be capable of detecting small quantities of highly-enriched uranium in a uranium enrichment plant. It could also be used to confirm that the feedstock to the enrichment plant is composed only of natural uranium. Feeding enriched uranium is the most direct route to the production of weapons-grade material. In the arms control arena, such detectors could be used to confirm that declared warheads are not removed from storage facilities, or that facilities declared not to contain warheads do not. Goldston also contributes policy analysis pieces to the Bulletin of the Atomic Scientists. Goldston’s fusion research interests are not included here.

The Science of Fission and Fusion Energy (AST/MAE/PHY/ENE 309). Nuclear fission power offers a low-carbon source of electricity. However, it also carries significant risks: nuclear proliferation (North Korea and Iran), major accidents (Fukushima), and waste disposal (Yucca Mountain). Fusion energy is moving towards realization as an alternative low-carbon source of energy from the nucleus. It carries fewer risks, but the timetable for its commercialization is not yet known. We delve into the physics of these energy sources, so that students can understand the issues for themselves. A benefit of this course is that students expand their scientific skills in applying them to important real-world problems. Offered: Spring 2019.
