Abstract

A neutron generator has a pre-moderator block of moderating material, an acceleration chamber, a vacuum pump evacuating the acceleration chamber to a moderately high vacuum, a plasma ion chamber opening into the acceleration chamber through an ion extraction iris, a gas source providing deuterium gas to the plasma ion chamber, a microwave energy source ionizing the gas in the plasma ion chamber, a primary and a secondary isolation well extending into the pre-moderator block, a water-cooled titanium target disk positioned at a lower extremity of the primary isolation well, the target disk biased to a substantial negative DC voltage, and electrically grounded metal cladding covering surfaces of the pre-moderator block. Ions extracted through the ion extraction iris are accelerated to bombard the titanium target producing energetic neutrons that pass through and are moderated by the pre-moderator block.
