Dr. Baruch Levush, a research physicist in the Naval Research Laboratory's Electronics Science and Technology Division, has received the Laboratory's E.O. Hulburt Annual Science Award. The award, NRL's highest civilian honor for scientific achievement, was established in 1955 to mark the retirement of NRL's first director of research, Dr. E.O. Hulburt. Dr. Levush is recognized for his "exceptional leadership in the field of vacuum electronics and his major contributions to research in the basic and applied science and technology of high power sources of coherent radiation."

Dr. Levush's research involves coherent radiation generation using electron beams. Early in his career, he focused on developing theories and computational models of the nonlinear interaction of electromagnetic modes in free electron lasers and cyclotron resonance masers (gyro-devices). In his current research, he focuses on the beam-wave interaction mechanisms operating in high power microwave and millimeter wave amplifiers and oscillators. As a result, Dr. Levush has developed a national and international reputation as an expert in nonlinear beam wave interaction physics.

Dr. Levush's work has had an influence on other researchers around the world. His research has inspired experiments, and has resulted in the development of innovative device concepts of importance to the Navy. For example, Dr. Levush received the 1999 DoD Robert L. Woods Award for his role in the successful development of the high average power (10kW), W-band gyro-klystron. NRL acknowledged his contributions to the development of the W-band gyroklystron with an Award of Merit for Group Achievement in 2002.

Most recently, Dr. Levush has initiated major national efforts in the field of computational physics as applied to the modeling of high power sources of coherent radiation. Working with ONR, scientists in his Branch, and a large array of key industry contractors, he has established NRL as the major US laboratory for the development of modern simulation codes for the simulation and design of vacuum electronics devices. This particular achievement has been widely recognized, both nationally and internationally. Last fall he was awarded the prestigious 2006 R&D 100 Award by R&D Magazine for MICHELLE, a software tool for three-dimensional modeling of charged-particle-beam devices. The physics-based vacuum electronics modeling and simulation code suite, the development of which Dr. Levush has led for the past eight years, has rapidly become a US industry standard for the analysis and design of many of vacuum electronic devices. For this work in particular, Dr. Levush has received three NRL Technology Transfer Awards (2000, 2001, 2005).

Dr. Levush has received the 2007 IVEC Award for Excellence in Vacuum Electronics from the Institute of Electrical and Electronics Engineers. Dr. Levush is recognized for his "pioneering contributions to the development of advanced models and design tools for vacuum electronic devices, and visionary leadership in the vacuum electronic industry." The International Vacuum Electronics Conference Award (IVEC) for Excellence in Vacuum Electronics was established in 2002 to recognize outstanding contributions to the field.

Dr. Levush is head of NRL's Vacuum Electronics Branch, which is the principal center for vacuum electronics research and development in the Department of Defense. Dr. Levush frequently provides advisory services to support external research programs in high frequency vacuum electronics. He also serves as a focal point for the planning and coordination of DoD research and development programs in vacuum electronics. His branch's technical areas of activity include:

  • the generation and amplification of high power sources for coherent electromagnetic radiation (UHF to THz),
  • highbrightness 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.

Dr. Levush received his M.S. degree in physics from Latvian State University, Riga, Latvia, and his Ph.D. in plasma physics from Tel-Aviv University, Israel. Prior to coming to NRL in 1995, he worked at the University of Maryland's Institute for Plasma Research as a research associate, associate research scientist, and senior research scientist. Dr. Levush is a fellow of the IEEE. He was an IEEE Electron Device Society Distinguished Lecturer in 2004 and an IEEE Nuclear Plasma Science Society Distinguished Lecturer in 2006. Dr. Levush is the co-author of more than 150 journal articles.
