About IVESC

BACKGROUND
The International Vacuum Electron Sources Conference series is devoted to the basic principles, technologies, and applications of various vacuum electron sources. The first IVESC was in Eindhoven, the Netherlands, in 1996 and chaired by S. Deckers (Philips), having grown from its Tri-service/NASA Cathode Workshop origins. It has expanded well beyond its Tri-service/NASA focus on thermal emission sources and vacuum electronics to include field, photo, and secondary emission physics and technology, and the devices using them. It meets biannually, alternating between Europe, Asia-Pacific, and the US.
