Measurements of pulsed electron beams emitted from plasma-focus devices

摘要

A dense plasma column, which is formed by a pulsed discharge within facilities of the Plasma-Focus (PF) type, is a source of the intense X-ray emission, pulsed electron beams and ion streams. Investigation of the electron beams can deliver information about development of plasma instabilities, which induce the formation of high-temperature plasma micro-regions in the form of hot-spots and/or filaments. The paper reports on recent studies of the pulsed electron beams within PF-type facilities.
