3. DESCRIPTION OF PROGRAM OR FUNCTION

ICOM calculates the transport characteristics of ion radiation for application to radiation protection, dosimetry and microdosimetry, and radiation physics of solids. Ions in the range Z=1-92 are handled. The energy range for protons is 0.001-10,000 MeV. For other ions the energy range is 0.001-100 MeV/nucleon. Computed quantities include stopping powers,  ranges; spatial, angular and energy distributions of particle current and fluence; spatial distributions of the absorbed dose; and spatial distributions of thermalized ions.

4. METHOD OF SOLUTION

The method of computation is statistical simulation of particle tracks on the framework of the model of condensed collisions with allowance for fluctuations of proton free  path, Monte-Carlo estimates on the simulated tracks, analytical formulae. Stopping powers are computed by empirical method, further  referred to as 'Ziegler et al.'. Some tables of stopping powers for  protons are also included. Users can extend the package by adding their own tables of stopping powers.

6. TYPICAL RUNNING TIME:  The program is interactive.
CCC-0651/01
The program was executed on a PC DELL Optiplex GXM 5100 equipped with a Pentium processor of 99 MHz and total memory of 32 MByte. The execution time of the sample problems depends on the number of histories. Typical execution times for a few thousand histories are of the order of a few dozens of seconds.
