Biography

Dr. Arefiev received his B.S. in physics (with Highest Honors) from Novosibirsk State University (Russia) in 1998. As an undergraduate student, he worked on physics of single species plasmas at the Budker Institute of Nuclear Physics (Novosibirsk, Russia). In 1999, Dr. Arefiev enrolled in the graduate program in physics at the University of Texas at Austin. His graduate work was supported by the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) project (NASA Johnson Space Center), Institute for Fusion Studies, and Fusion Research Center. Dr. Arefiev received his Ph.D. from The University of Texas at Austin in 2002, and his thesis advisors were Dr. Boris Breizman and Prof. Roger Bengtson. His thesis was a first-principles theoretical analysis of a plasma thruster that modeled the helicon plasma source, single-pass radio frequency heating, and particle and momentum balance. In 2003 Dr. Arefiev was selected by the Division of Plasma Physics of the American Physical Society to receive the Marshall N. Rosenbluth Outstanding Doctoral Thesis Award.

Dr. Arefiev joined the Institute for Fusion Studies in 2002. He collaborated with NASA and Ad Astra Rocket Company on the VASIMR project until 2007. His propulsion-related research included topics such as particle and power balance in magnetized plasma sources, self-consistent description of a super-Alfvénic plasma flow in a magnetic field (plasma detachment), and plasma expansion into a vacuum. Since 2002, Dr. Arefiev has also collaborated with the Center for High Intensity Laser Science at The University of Texas at Austin on problems of laser-target interactions. Specifically, Dr. Arefiev is engaged in studies of laser-irradiated micro-clusters and related phenomena such as fusion reactions from exploding clusters and harmonic generation.
