Abstract
The effect of residual space charge in the gas cell on fast neutral optics is considered. It is shown that within the paraxial approximation, the deleterious effects of this space charge may be reduced by more than a factor of 4 by lowering the beam perveance. This result is valid for a wide class of axial neutral production distributions.Keywords
