High Intensity, Pulsed, D-D Neutron Generator

摘要

Single ion-beam RF-plasma neutron generators are presented as a laboratory source of intense neutrons. Thecontinuous and pulsed operations of such a neutron generator using the deuterium-deuterium fusion reaction arereported. The neutron beam can be pulsed by switching the RF plasma and/or a gate electrode. These generators areactively vacuum pumped so that a continuous supply of deuterium gas is present for the production of ions and neutrons.This contributes to the generator's long life. These single-beam generators are capable of producing up to 1010 n/s.Previously, Ade1phi and LBNL have demonstrated these generators' applications in fast neutron radiography, PromptGamma Neutron Activation Analysis (PGNAA) and Neutron Activation Analysis (NAA). Together with an inexpensivecompact moderator, these high-output neutron generators extend useful applications to home laboratory operations.
