Dr. Richard Petrasso is a Senior Scientist and co-originator and Division Head of High-Energy-Density Physics at the Plasma Science and Fusion Center at MIT. With colleagues and students, he has coauthored over 200 technical papers on plasma physics. His recent work focuses on utilizing nuclear reactions and products for illuminating the basic physics of inertial confinement implosions and of high-energy-density laser-plasmas. In this work he, colleagues and students have utilized nuclear monoenergetic particles and associated reactions to discern fields, areal densities, asymmetries, and other important plasma properties of transient high-energy-density plasmas, be they reconnecting plasmas or directly or indirectly driven implosions.
Currently Dr. Petrasso is the PhD advisor of 4 MIT students who, in addition to working on projects and experiments focused on the Omega facility, are deeply involved in the fielding and analysis of 5 National Ignition Facility nuclear diagnostics, with which fuel and shell areal density, implosion symmetry, ion temperature, shock and compression bang times (from D3He implosion reactions), and primary yield are discerned. Reflecting this involvement, two of his recent PhD students, Dr. Daniel Casey and Dr. Michael Rosenberg, were the first students to ever utilize, analyze, and include as essential elements and chapters in their PhD theses, data from the National Ignition Facility. In addition, his recent PhD student, Dr. Mario Manuel, was just awarded the highly prestigious and coveted Marshall Rosenbluth Outstanding Doctoral Thesis award by the American Physical Society Division of Plasma Physics. Mario is the first PhD student supported by NNSA/DOE grants to ever receive this award.
Dr. Petrasso is also the chair and co-originator of the Omega Laser Users Group (OLUG), which is comprised of over 400 scientists, students, postdocs from 44 universities, 25 Centers and National Laboratories, and 15 different countries. OLUG seeks, with the strong participation of students and young researchers, to promote collaborations among Omega users, to facilitate novel physics experiments at the Omega facility, and to utilize and transfer platforms developed at Omega to the National Ignition Facility as well as to more modest facilities. In achieving these goals, OLUG partners closely with the management and technical staff of the Laboratory of Laser Energetics.
In 2013 Dr. Petrasso received the prestigious Edward Teller Medal, which recognizes pioneering research and leadership in the use of laser and ion-particle beams to produce extraordinarily high-temperature and high-density matter for scientific research and for controlled thermonuclear fusion. His citation for the award reads: “for pioneering the use of nuclear diagnostics for understanding inertial confinement fusion implosions and high-energy-density physics.” He is also a Fellow of the American Physical Society.
Dr. Petrasso received his PhD from Brandeis University in experimental atomic physics in 1972, and his B.S. from Oregon State University in 1967.
