Plasmas are a source of unbound electrons for charge neutralizing intense heavy ion beams to allow them to focus to a small spot size and compress their axial pulse length. The plasma source should be able to operate at low neutral pressures and without strong externally applied electric or magnetic

## Abstract The theoretical description of the positive column at low gas pressure is improved by taking into account both the space charge sheath at the wall and the radial variation of the radial ion temperature. Assuming the ion temperature being zero on the axis only, simplified moment equation
Highly ionized plasmas are being employed as a medium for charge neutralizing heavy ion beams in order to focus to a small spot size. Calculations suggest that plasma at a density of 1-100 times the ion beam density and at a length $0.1-1 m would be suitable for achieving a high level of charge neut
