Abstract
The effects of geometrical parameters (aspect ratio, aperture size, gaps) and electrical parameters (voltage distribution, beam energy) on single-beamlet profiles are investigated theoretically and experimentally on a two-stage ion accelerator over both a broad range of beam conditions and a wide range of angles (0 to ±11.5°). In general, the intensity distribution is non-Gaussian. Under optimum conditions, divergence angles half-width at half maximum less than 0.5° could be achieved even with large holes (0.9 mm). Shaping the plasma grid reduced the non-Gaussian wings and improved the beam transmission efficiency.This publication has 22 references indexed in Scilit:
