Collective Ion Acceleration in a Converging Waveguide.
Abstract
An ion acceleration mechanism is proposed in which ions are trapped and accelerated by a negative energy space charge wave. Under certain conditions, an electron beam propagating down a slowly converging metal guide can be accelerated. A low phase velocity space charge wave initiated at the large radius end of the guide, because it is supported by the beam, will also accelerate. By trapping ions in the potential wells of a low phase velocity negative energy wave, ion acceleration down the converging drift tube, can be achieved. The ion acceleration leads to the growth in amplitude of the negative energy space charged wave, thus maintaining the trapping.
