Portable, Low-cost Gamma Source for Active Interrogation

IB-2041

APPLICATIONS OF TECHNOLOGY:

ADVANTAGES:

ABSTRACT:

Ka-Ngo Leung, Tak Pui Lou and William Barletta of Berkeley have invented a cylindrical gamma generator that includes a coaxial RF-driven plasma ion source and target. A hydrogen plasma is introduced by RF excitation in a cylindrical plasma ion generator using an RF antenna. A cylindrical gamma generating target is coaxial with the ion generator, separated by plasma and extraction electrodes, which has many openings. The plasma generator emanates ions radially over 360 degrees, and the cylindrical target is thus irradiated by ions over its entire circumference.

STATUS: Issued Patent #7,596,197 available at www.uspto.gov. Available for licensing or collaborative research.
