Generation of neutron beam by the cylindrical discharge fusion device

Abstract

A discharge-type tube shaped neutron source has been developed utilizing fusion reactions on the surface of the cylindrical electrodes in the device. Neutron beam can be generated with adequate reflector design. From the neutronic analyses using the MCNP; three-dimensional particle transport code, using H2O or D2O as a reflector is essential to obtain narrow-shaped and sufficiently thermalized neutron beam. Experimental results supported the design and suggest the feasibility of table top fusion neutron beam based on this concept.
