The results indicate that the explosion time scale for the micron-sized clusters is much longer than that for nanometer-sized clusters. This implies that electrons below this energy would not get reaccelerated due to reflexing for a foil thicker than about 10 microns. This involves two treatment sessions a fortnight apart when about 50 x 50 micron focal argon laser burns are placed on the anterior trabecular meshwork. In the lower unit, the zircons range in length from 50 to 300 microns and in the upper unit from 100 to 350 microns. The resulting aerosol, of adjustable number density, was polydispersed with a mean particle diameter of about one micron. The distribution of the lesions was diffuse and was most striking in the intraacinar arteries (diameters of < 150 microns). Electrons are very forgiving of misalignments on the order of many microns. The particle size can be put at a few microns, although initially it can be much smaller. In a dusty plasma, a third charged species with size ranging from nanometer s to several hundred microns in diameter is present. The clay fraction of grain size smaller than two microns (< 2 m) was dispersed in water and separated by sedimentation techniques. These examples are from corpora and from sources on the web.
