Generation of neutron beam with the cylindrical discharge type fusion device

Abstract

With a cylindrical discharge type fusion device that generates fast neutron design of various combinations of reflectors, moderators and shield materials were studied for, the neutron beam with desired energy spectrum. Optimized reflector design and comparison of their materials are discussed by both experimental and numerical studies.

Optimizing the Electrode Configuration of a Cylindrical Discharge-Type Fusion Device by Computational and Experimental Analysis

“…We have tried to increase the reaction rate by coating the electrodes with hydrogen absorption materials such as titanium [9]. This concept is being developed as a neutron "beam" generator by using a cylindrical variation with reflectors and moderators [10][11][12]. However, the existing experimental machine, consisting of a grounded chamber and negatively biased cathode, has some problems; namely, unstable and inaccurate cathode support, undesirable discharge between the cathode and chamber wall, and overheating of the cathode after long operation.…”
