Focused Pulsed Neutron Source.

A non-reactor neutron source is disclosed that allows for a pulse intense current of ions to generate neutrons that are epithermal neutrons and provide low-energy neutron energy particularly suited for Boron Neutron Capture Therapy (BNCT) treatment. The present invention provides for a neutron fluence on a tumor which can be more than 10{sup 12} neutrons/cm{sup 2} and is generated into a time scale of less than 1 second. The radiation dose provided by the present invention is focused yet uniformly distributed so as to attack cancerous tissues and reduce collateral damage to healthy tissues.
