| Abstract: | An apparatus for the generation of neutron/gamma rays is described
including a chamber which defines an ion source, said apparatus including
an RF antenna positioned outside of or within the chamber. Positioned
within the chamber is a target material. One or more sets of confining
magnets are also provided to create a cross B magnetic field directly
above the target. To generate neutrons/gamma rays, the appropriate source
gas is first introduced into the chamber, the RF antenna energized and a
plasma formed. A series of high voltage pulses are then applied to the
target. A plasma sheath, which serves as an accelerating gap, is formed
upon application of the high voltage pulse to the target. Depending upon
the selected combination of source gas and target material, either
neutrons or gamma rays are generated, which may be used for cargo
inspection, and the like. |
