Abstract: A field emitter includes a cathode, a field emission point part, a first anode, a charge storing plate, and a second anode. The field emission point part faces the first anode and is disposed at a first surface of and electrically connected to the cathode. The charge storing plate is disposed at a second surface, opposite the first surface, of the cathode. The second anode faces the second surface of the cathode. The charge storing plate is interposed between the second anode and the second surface of the cathode. Even if substantially the same electric field is formed in the field emitter as in a field emitter without the charge storing plate, the field emitter having the charge storing plate induces a more effective field emission current than the field emitter without the charge storing plate.

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.
