Abstract: An apparatus and method for analyzing and imaging chemical compounds within a test subject uses subatomic particle activation. The test subject (and chemical compounds contained therein) is irradiated by non-thermal neutrons, thereby generating thermal neutrons within the test subject and stimulating the emission of gamma rays. Gamma ray detectors detect the emitted gamma rays and energy signals derived from the gamma ray detectors are filtered to eliminate non-relevant spectral artifacts.

Abstract: An apparatus and method for detecting, locating, and analyzing chemical compounds located within a test subject using subatomic particle activation. In a first embodiment, an excitation source excites a target to simultaneously produce beams each consisting of certain subatomic species, for example fast neutrons and alpha particles. The test subject (and chemical compounds contained therein) is irradiated by the fast neutrons, thereby stimulating the emission of prompt gamma rays. Gamma and alpha detectors are positioned relative to the test subject and target(s) so as to detect the emitted prompt gamma rays and alpha particles in substantial coincidence, and the known physical relationship between the beams is used to spatially locate the activated chemical compound.

Abstract: A self-colliding particle beam apparatus is capable of increasing stored ion density by a factor 10 and increasing ion confinement time by a factor of 10 to thereby increase the collisional energy between particles. The self-collider comprises essentially a superconducting magnet, an ultra-high vacuum system and an electrostatic stabilizer. The self-collider apparatus can be employed as part of a beam energy multiplier by combining it with an injector, including an ion source, an accelerator and a beam transport system. By increasing the stored ion density by a factor of 10 and by increasing the ion confinement time by a factor of 10, the increase in collisional probability between two particles increases by a factor of 1,000; this is due to the fact that the number of collisions is proportional to (density).sup.2 .times.(confinement time) and therefore 10.sup.2 .times.10 equals 1,000.
