R. Lawrence Ives, Ph.D.

R.L. Ives Dr. Ives received the Ph.D. degree in Plasma Physics in 1984 and joined Varian Associates, Inc. as a gyrotron engineer. In 1986 he became manager of the High Power Klystron Department, which was responsible for klystron development and production from UHF through C-Band. Dr. Ives founded Calabazas Creek Research, Inc. in 1994 and led development of high power RF loads, multiple beam and sheet beam klystrons, backward wave oscillators, gyrotron, TWTs, inductive output tubes, controlled porosity reservoir cathodes, advanced electron guns, high power RF windows, reservoir photocathodes, and advanced coatings for emission suppression and corrosion mitigation.

Michael Read

Michael Read, Ph.D.

Dr. Michael Read – Dr. Read received his Ph.D. in 1975 from Cornell University in Electrical Engineering and Plasma Physics. He worked at the Naval Research Laboratory (NRL) and from 1983 to 1986 was head of the Gyrotron Oscillators and Plasma Interactions Section of Plasma Physics Division. In October 1986, he joined Physical Sciences Inc., where he became Manager of the Electromagnetic Technology Area. Dr. Read joined Calabazas Creek Research in 1999, where he is responsible for electron gun, magnetics, and RF circuit design. He is currently leading development of a multiple beam electron gun for a Ka-Band TWT, a 10 MW, L-Band annular beam klystron, and advanced output coupling for high power, mm-wave gyrotrons.

Patrick Ferguson received his Ph.D. degree from UCLA in 1975 and began his professional career at Hughes Aircraft. Throughout his career he has made significant contributions at many companies in the microwave source industry, including Varian Associates, Litton Electron Devices, Physics International, and Martin Marietta Corp. In 1991 he founded MDS Company, specializing in high power RF sources for accelerators and colliders. MDS provided consulting services to numerous organizations and teamed with national laboratories on RF component and source development.

George Miram

George Miram passed away in early 2012, after more than fifty years advancing cathode research. He was truly one of the great cathode scientists of our time. In April 2012, I had the honor of presenting the first George Miram Award for Achievement in Cathode Science. This award was established by the International Vacuum Electron Sources Conference to honor George’s contributions to the field. Below is part of that presentation.

April 25, 2012

There is no one in this room that has not been impacted by George Miram. If you have flown on an airplane, been x-rayed, or watched a TV, then you have benefited from George’s work. In fact, there are probably few people on this planet who have not been impacted by George and his achievements.

Born of Russian parents in China, George’s personal history is a fascinating story in itself. With limited opportunities for advanced education, he became, arguably, the premier cathode scientist of our time. For almost 30 years, George directed Varian’s electron optics laboratory designing electron guns and advancing cathode physics, materials science, chemistry, and mechanical design. He published countless technical papers and holds more than 25 patents.

Contrary to published rumors, George never retired. Until the last days of his life, he was engaged in understanding and advancing cathode technology, some of it pioneered by the winner of the award today. One of his most enduring contributions is the many engineers and scientists that he trained over the years. He was a superb mentor and teacher, and was always available to answer questions or explain complex processes. I spent many hours with George as he tried to explain the intricacies of cathode physics. I was humbled by the immensity of his knowledge, grateful for his patience, and honored that he would take the time and effort to explain things to me.

For his family, several who are here today, I know it’s often difficult to appreciate the significance of what we do. We’re engaged in highly technical work, and there are many things that even we do not understand. Perhaps knowing this industry established its highest award for cathode technology in his name is an indication of the high esteem and admiration we have for George and his accomplishments.
