| DESCRIPTION: | STOPOW calculates a set of stopping power values and ranges of fast ions in matter for any materials. Furthermore STOPOW can calculate a set of values for one special auxiliary function (e.g. kinematic factors, track structure parameters, time of flight or correction factors in the stopping function) . The user chooses the physical units for stopping powers and ranges and the energy range for calculations. |

| METHOD OF SOLUTION: | The program uses the method of ZIEGLER et al. with user-defined non-relativistic and relativistic corrections in the energy range up to 100 MeV/amu. For higher energies the treatment of AHLEN is used. The program calculates the stopping power and ranges for an energy grid with logarithmic equally-spaced steps. These values are given as arrays, printing tables or output files. |
| COMPUTER: | MLT-PLTFM |
| OPERATING SYSTEMS: | OS 7.1 ESComputers (like IBM 360,370 series)
SCP1700 (CPM) 16 bit PC |
| SOFTWARE LIMITATIONS: | Ions from H up to super heavies and compound targets with up to 30 different atomic constituents may be considered. The target compound can also contain up to five sub-compounds. This means the target is 1 keV/amu - 10 GeV/amu. Maximum incident energy can easily be increased by increasing the storage area. The program gives reasonable values up to 100 GeVfamu, it has not been tested for higher energies. The program accepts all the elements up to uranium, and for the input of a special target element identification of the element by atomic number is all that is needed. Batch and interactive input is possible.
TYPICAL RUNNING TIME Problem dependent. For 183 logarithmic equally-spaced energies and a five-element target, a few Cpu seconds on ES 1055m/56 computers. On a 16bit PC with 8087 arithmetic processor, about 10 - 20 seconds. |
