Dear Colleagues [Welcome message]

The main goal of the organizers is to provide wide range of topics for discussion on current theoretical and experimental achievements between all involved scientists, from students to professors and leading research scientists of commercial enterprises. These joined conferences will extend the view of key points in technology of electron cathodes and guns (applications of vacuum electron sources; new materials, incl. nano-materials - their production, processing and modern equipment), and give an opportunity to learn about recent results in physics of electron emission (field, thermo-, photo-, secondary, and explosive electron emission, as well as photoelectron spectroscopy), and also about electron beam modelling and optimization.
