摘要: An image intensifier device includes: an intensifier tube with at least one photocathode, a micro-channel plate and a conversion element, arranged in that order one after another, and an electric power supply module configured to supply at least one respective polarisation voltage to each of the elements of the intensifier tube. The electric power supply module extends in a region located upstream of the photocathode, on the side of the photocathode opposite to the micro-channel plate. Thus, a space is cleared located downstream of the intensifier tube in the direction of travel of the photons and of the electrons in the image intensifier device. This allows reducing the size of the image intensifier device for example by bringing an eyepiece closer.

摘要: Radial radio frequency (RF) electron guns and radial RF electron gun systems are provided that are capable of generating an electron beam that can propagate either radially inward, towards the axis of a cylinder, or radially outward from the axis. A beam source capable of generating a radially inwardly propagating electron beam, while perhaps not particularly useful as a source for a higher-energy accelerator, offers potential advantages for materials processing, as the geometry allows irradiation from all sides of an enclosed material flow with a single structure. Other potential applications include, but are not limited to, atmospheric plasma generation, radiation damage testing, and possibly, novel electron lens-type devices for hadron accelerators.
