General Aspects

The programm system STOPOW is designed for the theoretical characterisation of trajectories, energy loss and range of light ions. Its advantage over other transport programs like SRIM lies in its capability to directly output important dosimetrical quantities. I.e. the restricted energy loss can be calculated using different threshold energies for the δ-electrons, or the energy loss at the passage through material of varied depths.

The programm uses Ziegler's method with user-defined non-relativistic and relativistic correction for energies up to 100 MeV/amu. For higher energies, Ahlen's treatment is adopted. Overall, stopping power and range are usually calculated for a pattern of logarithmically equidistant energies.
