Paper Abstract

A small source, based on a hollow cathode vacuum discharge, produces nanosecond X-ray pulses, with a stored electrical energy less than 1 Joule. Previous measurements have shown that the emitting region is of small size (< 50 μm) and very reproducible in position (δ1 < 50 μm). This type of discharge creates a powerful beam of electrons coming from the hollow cathode plasma. Two different and successive emission mechanisms exist: a beam-target one from trigger plasma and a beam-plasma interaction during the breakdown phase. The spatial distribution is imaged using a highly sensitive camera.
