ABSTRACT:
A hydrogen ion accelerator produces a beam current that is at least ten times greater than the current supplied by an electrostatic generator by recycling the unreacted portion of the beam. In one application, a 1.76 MeV proton beam is used to generate 9.172 MeV gamma rays for detecting explosives (nitrogen) via either the .sup.13 C reaction. The cross-section of the 1.76 MeV proton beam with the carbon 13 target is such that over 95 percent of the beam passes through the target unreacted. In a preferred embodiment, a proton source (52) disposed within a high voltage electrode (32) forms a proton beam that is accelerated along the length of an acceleration tube (46), is bent 180.degree. by bending magnets (70, 72), passes through a target foil (76), is decelerated along the length of a deceleration tube (82), and is returned to the high voltage electrode (32) where the energy contained in the beam is recaptured.
