HIGH ENERGY CRYSTAL GENERATORS AND THEIR APPLICATIONS

摘要

Ferroelectric, pvroelectric and piezoelectric crystals (12) are used to generate spatially localized high energy (up to and exceeding 100 keV) electron and ion beams, which may be used in a wide variety of applications including pulsed neutron generation, therapeutic X-ray/electron devices, elemental analysis, local scanning chemical analysis, high energy scanning microscopy, point source compact transmission electron microscopy, compact ion beam sources, positron sources, micro-thrusters for ion engines, and improved fusion efficiency especially of the Farnsworth type. The high-energy emission can be created by simply heating (16) the material (12) or by application of external coercive electromagnetic and acoustic fields.
