Presented at NRL headquarters, October 28, 2009, by Chief of Naval Research, RADM Nevin P. Carr, the award, named in honor of Captain Robert Dexter Conrad (1905-1949), recognizes and rewards outstanding technical and scientific achievement in research and development for the Department of the Navy (DoN).

"Dr. Levush's outstanding and pioneering work has led to the successful development of world-class vacuum electronic devices," said Frank Klemm, Ph.D., superintendent, NRL Tactical Electronic Warfare Division. "His vision to create simulation-based design methodologies for vacuum electronic devices allows for improved, less costly and more capable Department of Defense systems."

Simulation tools pioneered by Levush's team of computational physicists have been widely adopted by the U.S. vacuum electronics industry to support new vacuum electron device development in private business and academia with continued application at the Naval Research Laboratory.

The design tools developed by Levush's research team, including simulation codes for traveling wave tubes (CHRISTINE); gyro-devices (MAGY) and klystrons (TESLA); and a three-dimensional beam optics code (MICHELLE), have been transitioned to all U.S. based manufacturers of vacuum electronics devices—the team is comprised of NRL scientists D. Abe, J. Calame, S. Cooke, J. McDonald, and A. Vlasov and researchers and scientists D. Chernin, I. Chernyavskiy and J. Petillo, Science Application International Corporation; Professor T. Antonsen Jr., University of Maryland at College Park; E. Nelson, Los Alamos National Laboratory; K. Nguyen, Beam Wave Research and J. DeFord of AWR/STAAR, Inc.

Early in his career, Levush focused on the development of theories and computational models of the nonlinear interaction of electromagnetic modes in free electron lasers and gyro-devices. Today, his research involves coherent radiation generation using electron beams with active involvement in the development of theoretical models and computational tools for analyzing the operation of vacuum electron devices with a focus on the invention of new concepts for high power amplifiers operating at frequencies ranging from one to 1,000 gigahertz (GHz).

Levush received his master's of science (M.Sc.) in physics from Latvian University in Riga, Latvia in 1972. In 1973 he immigrated to Israel where he pursued a doctorate in plasma physics at Tel-Aviv University. Upon completion of his Ph.D. in 1981 he received the Dr. Ch. Weizman Postdoctoral Fellowship and spent several years as a postdoctoral fellow at the University of Maryland, College Park, where he later joined University of Maryland's Institute for Plasma Research as a research scientist in 1985.

In 1995, Levush began work at NRL as head of the Theory and Design Section of the Vacuum Electronics Branch of the Electronics Science and Technology Division and in 1997 became responsible for developing a suite of new design codes for vacuum electron devices under the auspices of the Office of Naval Research, becoming head of NRL's Vacuum Electronics Branch in 2003.

NRL's Vacuum Electronics Branch is the principal center for vacuum electronics research and development within DoD. As branch head, Levush frequently provides advisory services to support external research programs in vacuum electronics. His branch's technical areas of activity include generation and amplification of high power sources for coherent electromagnetic radiation from Ultra-High Frequency (UHF) to terahertz (THz), high brightness electron-beam optics, surface science related to electron emission mechanisms, development of new types of microwave absorbing composite materials, vacuum microelectronics, development and application of the nonlinear theory of the beam-wave interaction and advanced computational physics for the modeling and simulation of vacuum electronic devices.

Levush has received three NRL Technology Transfer Awards (2000, 2001, and 2005), has been a fellow of IEEE since 2001 and holds numerous awards including the 1999 Robert L. Woods Award of the U.S. Department of Defense (DoD) for his role in the successful development of a 10 kilowatt (kW) average power, W-band gyro-klystron; NRL's 2002 Award of Merit for Group Achievement as part of the W-band gyro-klystron and WARLOC Radar Team; R&D100's 2006 Award for MICHELLE, a 3D charge-particle-beam optics software tool; IEEE's 2007 International Vacuum Electronics Conference Award; NRL's 2007 E.O. Hulburt Annual Science Award (NRL's highest civilian honor for scientific achievement); and the 2009 Captain Robert Dexter Conrad Award for scientific achievement, signed by the Secretary of the Navy.

Levush is currently an IEEE Nuclear Plasma Science Society distinguished lecturer and co-author of more than 170 journal articles.
