George Miram Mr. George Miram has been involved in electron gun technology for more than 35 years and is widely recognized as one of the world's foremost authorities on electron guns and cathode technology. His association with Calabazas Creek Research, Inc. began in 1997 as part of a team to develop a multiple beam electron gun for a 75 MW, X-Band klystron. Currently he is involved in developing multiple beam guns for MW radar applications, advanced cathode research and development of field emission arrays for RF sources. Mr. Miram has also provided consulting support for advanced gun development at Stanford Linear Accelerator Center, Lawrence Berkley Laboratories, University of California at Davis, and other national and international research laboratories and organizations. Since 1963, Mr. Miram has specialized in the design of a broad range of electron guns and magnetic circuits. He introduced a new concept in a nonintercepting gridded gun—the "mosaic cathode" approach (1967)—that was successfully used in the development of a superpower switch tube. Mr. Miram has a world-renowned reputation in this field and has been involved in the analysis of Russian high-power electron guns. In 1968, Mr. Miram designed a gun for the X-3030A, an X-hand superpower klystron, which produced 1 MW of CW if power and 2.5 MW of dc beam power. In 1973, he developed a new focusing-grid-type nonintercepting gridded gun in which a specially treated shadow grid was attached directly to the cathode surface. These guns are used in Communications & Power Industries, Inc. (CPI) helix and coupled-cavity TWTs. For almost 30 years, Mr. Miram was in charge of the Varian (now CPI) Microwave Tube Product's electron optics development laboratory, responsible for the design and development of gun optics for new klystrons and traveling-wave tubes. Mr. Miram has published a number of technical papers relating particularly to gridded electron guns and holds 25 U.S. patents.
