We are pleased to announce that the Fifteenth International Vacuum Electronics Conference (IVEC 2014) will be held on 22-24 April 2014 in Monterey, California. With technical co-sponsorship from the IEEE Electron Devices Society (EDS), the conference will provide a forum for scientists and engineers from around the globe to present the latest developments in vacuum electronics technology at frequencies ranging from the UHF to THz frequency bands. IVEC was originally created in 2000 by merging the U.S. Power Tubes Conferences and the European Space Agency TWTA Workshops. Now a fully international conference, IVEC is held every other year in the U.S., and in Europe and Asia alternately every fourth year. After the successful and enjoyable meeting in Paris, France in May, IVEC 2014 will return to its beautiful U.S. location in the city of Monterey.
