FOCUSING A PARTICLE BEAM USING MAGNETIC FIELD FLUTTER
First Claim
1. A particle accelerator comprising:
- a voltage source to sweep a radio frequency (RF) voltage in a cavity to accelerate particles from a plasma column, the cavity having a magnetic field causing particles accelerated from the plasma column to move orbitally within the cavity, the magnetic field having flux that bows at edges of the cavity;
a regenerator to provide a magnetic field bump within the cavity to thereby change successive orbits of the particles accelerated from the plasma column so that, eventually, particles output to an extraction point, the regenerator being located at a radius in the cavity relative to the plasma column; and
ferromagnetic arrangements located in the cavity proximate to the radius, each ferromagnetic arrangement providing a magnetic field bump, wherein ferromagnetic arrangements adjacent to the regenerator are separated from the regenerator by a space.

Abstract
An example particle accelerator may include the following: a voltage source to sweep a radio frequency (RF) voltage in a cavity to accelerate particles from a plasma column, where the cavity has a magnetic field causing particles accelerated from the plasma column to move orbitally within the cavity, and where the magnetic field has flux that bows at edges of the cavity; a regenerator to provide a magnetic field bump within the cavity to thereby change successive orbits of the particles accelerated from the plasma column so that, eventually, particles output to an extraction point, where the regenerator is located at a radius in the cavity relative to the plasma column; and ferromagnetic arrangements located in the cavity proximate to the radius, where each ferromagnetic arrangement provides a magnetic field bump, and where ferromagnetic arrangements adjacent to the regenerator are separated from the regenerator by a space.

13. A particle accelerator comprising:
-
a voltage source to sweep a radio frequency (RF) voltage in a cavity to accelerate particles from a plasma column, the cavity having a magnetic field causing particles accelerated from the plasma column to move orbitally within the cavity, the magnetic field having flux that is substantially straight throughout the cavity; wherein the cavity comprises alternating regions of first magnetic field and second magnetic field, the first magnetic field being different from the second magnetic field to produce magnetic fluctuations having a component at an angle that is substantially perpendicular to particle orbits within the cavity. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
