Abstract: The Centroidal Cyclotron reveals an apparatus and method for accelerating and trapping charged particles in a solenoid magnetic field. An oscillating electric field is applied generally transverse to the magnetic field axis accelerating and trapping charged particles by their inherent cyclotron frequency at a given magnetic field of the solenoid magnetic field producing charged particle orbits with minimum canonical angular momentum orbits and gyro-phase synchrony.

Abstract: The Circular Hollow Anode Ion Electron Plasma Source is a hollow anode ion electron plasma source presenting the limited area of the inner surface only of an anode exit aperture, leading to high brightness and high efficiency in a simple robust plasma device.

Abstract: The Energy Density Intensifier for Accelerating, Compressing and Trapping Charged Particles in a Solenoid Magnetic Field is a method and apparatus operable upon a population of charged particles possessing an initial angular momentum (magnetic moment) within a vacuum mirror solenoid magnetic field. An electric field is applied generally along the longitudinal magnetic field axis accelerating, compressing and trapping the charged particles by their magnetic moment against the radial component of the field gradient of the mirror magnetic field of the solenoid magnetic field, by means of the electric force established by the electric field.

Abstract: A closed drift Hall Current accelerator with a split solenoid Hall field, a radial injection collimated gas source, an anode, intermediate Hall effect ionization magnetic field structures and intermediate acceleration electrodes, for injection of ions into the solenoid field. The Hall Effect field in this case is in the gap of the return field of the split solenoid magnetic field.

Abstract: The present patent letters discloses a Hall Current accelerator with a solenoid Hall field, a collimated gas source, an anode, intermediate Hall effect ionization magnetic field structures and intermediate acceleration electrodes. The Hall field in this case is the end fringe field(s) of a common solenoid magnetic field.
