1. NAME AND TITLE
TRIPOS: Monte Carlo Ion Transport Analysis Code.
University of California, Los Angeles, California.
3. CODING LANGUAGE AND COMPUTER
Fortran 77, Cray.
4. NATURE OF PROBLEM SOLVED
TRIPOS is a versatile Monte Carlo ion transport analysis code. It has been applied to the treatment
of both surface and bulk radiation effects. The media considered is composed of multilayer polyatomic
5. METHOD OF SOLUTION
TRIPOS couples the power-law cross sections and universal potentials together to treat the atomic
collision process. This coupling is made possible by the development of the Blanchard-Ghoniem-Chou
integration scheme for the atomic scattering integral.
6. RESTRICTIONS OR LIMITATIONS
Graphics routines have been disabled in the RSIC source.
7. TYPICAL RUNNING TIME
On a Cray X-MP, the sputtering problem took about 0.3 seconds of cpu time; the ion implantation
problem took about 1287 seconds; the surface modification and evolution problem took about 30
8. COMPUTER HARDWARE REQUIREMENTS
TRIPOS runs on various Cray computers: Cray 1, Cray 2 and Cray X-MP.
9. COMPUTER SOFTWARE REQUIREMENTS
The CFT compiler is required.
