Abstract
A Boron neutron cancer treatment system has a secondary moderator having a central treatment chamber, and several generators, each comprising a pre-moderator block, an acceleration chamber, a vacuum pump engaging the acceleration chamber at a right angle, a plasma ion chamber opening into the acceleration chamber, a gas source providing deuterium gas to the plasma ion chamber, a microwave energy source ionizing the gas in the plasma ion chamber, a cylindrical primary isolation well extending into the pre-moderator block, a secondary isolation well surrounding the primary isolation well, and a water-cooled titanium target disk at a lower extremity of the isolation well. The neutron generators are positioned around the secondary moderator with the axis of each acceleration chamber passing through the center of the treatment chamber, and with the angled sides of the neutron generators fully adjacent.
