Abstract
An apparatus having a set of apertures of selected diameters, each aperture being positioned in a multiaperture assembly that can be moved to bring selectively each of these apertures into a path of a beam. This enables control of the diameter of an aperture in a beam and also enables accurate positioning of that aperture so that it is centered on the beam where it is moved to a position of alignment with the beam.
