AT.Stopping.Power: AT.Stopping.Power
In libamtrack: Computational Routines for Proton and Ion Radiotherapy

Description Usage Arguments Value See Also

Retrieves the electronic stopping power in keV/um for the requested energies and particles for a specified material and data source. The data source is thereby given via its name (s. AT_StoppingPowerData.h for details), except for data that should be read from a file, in this case the (path and) filename has to be provided. In this case, the user has to make sure that energy and stopping power units are correct and that the data match the given material (use material.no = 0 for custom-defined material) for density scaling. The file has to be plain ASCII with three columns (separated by space) charge, energy, and stopping power and sorted in ascending order by first charge than energy any alphanumeric comment can be inserted (in separate lines)
