Abstract: A high-brightness pulsed electron source, which has the potential for many useful applications in electron microscopy, inverse photo-emission, low energy electron scattering experiments, and electron holography has been described. The source makes use of Cs atoms in an atomic beam. The source is cycled beginning with a laser pulse that excites a single Cs atom on average to a band of high-lying Rydberg nP states. The resulting valence electron Rydberg wave packet evolves in a nearly classical Kepler orbit. When the electron reaches apogee, an electric field pulse is applied that ionizes the atom and accelerates the electron away from its parent ion. The collection of electron wave packets thus generated in a series of cycles can occupy a phase volume near the quantum limit and it can possess very high brightness. Each wave packet can exhibit a considerable degree of coherence.

Abstract: Actuator mechanisms on the heart are of several types. In preferred embodiments, they are generally simple, durable, mechanical assemblies and are driven by power delivered from a remote location, generally outside the chest, by a variety of mechanisms. The invention teaches physical mechanisms (1) for transfer of cyclic power from outside the chest to the region of the heart for that purpose, either as translational or rotary motion. Also taught are electromechanical converting mechanisms suitable for delivering power to those transfer devices. The embodiments described herein for either transmission of energy from a site of generation to a conduit (2, 10, 22), and of conduits that then deliver energy to heart actuators, have contours and interfaces designed to promote a favorable biologic response similar to the pseudosynovial capsules that surround artificial joints. Further, design features are chosen to avoid both non-vented gas-filled chambers and static collections of tissue fluid.
