Abstract
A system has been developed for semi-automated determination of the charges of heavy ions recorded in nuclear emulsions. The profiles of various heavy ion tracks in emulsion both accelerator beam ions and fragments of heavy p rojectiles, were obtained with a CCD camera mounted on a microscope. The de pendence of track profiles on illumination, emulsion grain size and density , background in emulsion, and track geometry was analyzed. Charges of the f ragments of heavy projectiles were estimated independently by the delta ray counting method. A calibration of both width and height of track profiles against ion charges was made with ions of known charges ranging from helium to gold nuclei.. (C) 1999 Elsevier Science B.V.
