Description

A collimator has been constructed to produce high-quality ion beams with diameters and angular divergences as small as 1 μm and 1 μrad, respectively. The slit scattering could be effectively suppressed by using properly shaped and manufactured collimator slits. The quality of the collimator was investigated for collimator diameters between 20 μm and 1 μm using 1 MeV H+ and H3+ beams. A design for a proton scanning microprobe making use of this collimator system and a small quadrupole doublet is discussed. (Auth.)
