Pulse Laser Deposition method for UV-Photocathode production

Production method of alkali halides UVphotocathodes durable to environment exposure was proposed. Photocathodes with highhomogeneous and adhesion photoemission layerwere made. Quantum yield measurements results ofmanufactured photocathodes are presented.Developed method is promising for creation of highaperture electron injectors and detectors

Superluminal source of directional pulsed wideband electromagnetic radiation

A photoemission source of directional pulsed wideband electromagnetic radiation in the microwave region is developed, and the time profile of the generated pulse is investigated. The source is a vacuum photodiode of a parabolic shape in which a Cherenkov radiation pulse is formed by an electron current wave excited by an incident laser pulse and propagating along the surface of the anode mesh with a phase velocity higher than the speed of light. © 2014, Allerton Press, Inc
