DESCRIPTION
MARLOWE is a computer application available from the
Oak Ridge National
Laboratory.
The MARLOWE program simulates atomic collisions in crystalline targets
using binary collision approximation. It traces the consequences of
launching an energetic atomic projectile, from either an external beam
or an interior site, into a target. The program follows the slow down
of the primary particle and, if desired, that of all target particles
which are displaced from their lattice sites until they either leave the
target or fall below a selected kinetic energy level. Output from MARLOWE
is a long tabular list of collision location, collision time, kinetic
energy, and directional cosines of particle movement.
This project involved the writing of a post-processor for the MARLOWE
output to parse the information into a form compatible with Data Explorer,
and the writing of a set of Data Explorer networks to animate and display
the collisions over time.
The three applications will be bundled together for use by Nuclear
Engineering students participating in the Penn State
ECSEL program.
