MARS --Multiple-Array System using Combinatorial Geometry


The MARS geometry package developed by ORNL was used as the geometry routine of EGS4 by O. Sato at MRI Inc. et al. The MARS allows the users to model many rectangular arrays containing a geometry modeled by a combinatorial geometry with unlimitted aray nesting.

Linux version

The modified source programs of UCMARS for PC-Linux were archived in ucmars-linux.tar.gz. README-linux is a README file and UCMARS.pdf is the manual (modification of KEK internal 94-12).
The modifications were made for followings.
1. MARS subroutine libraries and a user code were modified for g77.
2. No. of Histories can be specified in input data.
(Caution: Input data were changed from previous version.)
3. RANMAR random number routine was used instead of RAN6(integer overflow).
4. Fractional standard deviations of energy depositions are printed.
