Abstract
Ferroelectric, pyroelectric and piezoelectric crystals 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 the material or by application of external coercive electromagnetic and acoustic fields.
