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.本發明揭示一種實例性粒子加速器,其可包含以下各項:一電壓源,其用以在一腔中掃掠一射頻(RF)電壓以使粒子自一電漿柱加速,其中該腔具有致使自該電漿柱加速之粒子在該腔內沿軌道移動之一磁場,且其中該磁場具有在該腔之邊緣處彎曲之通量;一再生器,其用以在該腔內提供一磁場突增以藉此改變自該電漿柱加速之該等粒子之連續軌道以使得最終粒子輸出至一提取點,其中該再生器位於該腔中相對於該電漿柱之一半徑處;及鐵磁配置,其位於該腔中接近於該半徑處,其中每一鐵磁配置提供一磁場突增,且其中毗鄰於該再生器之鐵磁配置藉由一空間與該再生器分離。700‧‧‧腔701‧‧‧粒子源702‧‧‧再生器703‧‧‧提取通道711‧‧‧磁結構802‧‧‧振顫磚803‧‧‧振顫磚
