Measurements of Vacuum Ultraviolet Radiation, Neutrons, and Ions from the Interaction of an Intense Relativistic Electron Beam and a Deuterated Polyethylene Target.
Abstract
The interaction of a tightly pinched relativistic electron beam from a Bennett cathode and a deuterated polyethelene target has been studied using diagnostics sensitive to vacum ultraviolet and neutron radiation. Target plasmas produced by three electron accelerators were analyzed. X-ray pinhole camera photographs indicated plasma sources equal to or less than 75 micrometers in diameter. Maximum plasma temperatures of 50 ev were detected and conversion efficiencies of approximately 0.1% from electron beam energy to X-ray radiation were measured. Neutron production was attributed to the beam-target mechanism resulting from the acceleration of up to 10 to the 14th power ions/str-MeV across the anodecathode gap. (Author)
