Arie Lew Eichenbaum was born in Warsaw, Poland, in 1933. He received the BSc. and M.Sc. degrees in electrical engineering from the Polytechnic University of Brooklyn (PUB), New York, in 19.53 and 19.54, respectively. During his studies for the latter, he was the recipient of a research fellowship at the Weber Research Inqtitute of the PUB. From 1954 to 1964, he was a Member of the Research Staff of the RCA Research Laboratories in Princeton, NJ, where he worked in the fields of electron optics, plasmas and low noise traveling wave tubes. In 1964, he joined ELTA Electronics Industries in Israel, where he headed engineenng and development activities in Elint and EW and subsequently established and managed MISHAL-the microwave tube facility. Since 1989 he has been engaged in research work on free electron masers in the Physical Electronics Department of the Engineering Faculty at Tel-Aviv University, and studies philosophy, history, and Bible at Bar-Ilan University. From 1966 to 1993 he was also active as a part-time Lecturer at the Technion and at Tel-Aviv University giving courses on microwave tubes, radar, elint and EW, and microwave components. Mr. Eichenbaum has served as the IEEE’s National Secretary in Israel Avraham Gover (M’74SM’89) received the B.Sc. and M.Sc. degrees in physics with distinction from Tel-Aviv University, in 1968 and 1971, respectively, and the Ph.D. degree in applied physics and elec-tncal engineering from Caltech, Pasadena, CA, in 1975 Since 1977, he has been a Professor of Electrical Engineering in the Department of Physical Electron-ics, Faculty of Engineering at Tel-Aviv University. His main research field is free-electron lasers, a field in which he made pioneenng contributions starting in 1975 (with A Yariv at Caltech) He now heads aconsortium fix development an electrostatic accelerator FEL in Israel Dr is a member Of the OSA

N2 - The electrostatic-accelerator free-electron laser (EA-FEL) operating at mm wavelength is considered as a source for energy transfer through the atmosphere to a high altitude platform. The high average power and high efficiency attainable from appropriately designed EA-FEL make it a suitable candidate as an efficient source of mm-waves for power beaming from a ground station. Various aspects of the FEL as a high power oscillator (operating voltage, c-beam current, gain and efficiency) are reviewed; design tradeoffs are described. The study includes consideration of typical requirements of power beaming to a high altitude platform such as atmospheric absorption versus frequency and transmitting and receiving antenna requirements. A conceptual design of a compact, moderate voltage (0.5-3 MeV), high current (1-10 Amp) EA-FEM operating in the mm-wavelength band is presented as an efficient power source for space beaming. The FEM design parameters are presented based on analytical and numerical models. Expected performance parameters of an FEL (gain, energy conversion efficiency, average power) are discussed as related to the proposed application.
