Ranges and energy-loss measurement of 1.0-4.7 MeV u Si-28 ions in Makrofol-G using PADC as detector

Ranges and energy-loss up to 4.7 MeV/u Si-28 ions in Makrofol-G polymer hav e been determined using a nuclear track technique. Polyallyldiglycol carbon ate (CR-39) detectors were calibrated using Al degraders to determine the d egraded energy of Si-28 ions after passing through the different stacks of Makrofol-G placed in the staircase configuration. The mean ranges of Si-28 in Makrofol-G have also been determined at different energies between 1.0 M eV/u and 4.7 MeV/u. The experimental results are discussed and compared wit h the theoretical values obtained from four different computer codes.
