=================================================================

I have a body of menu-driven programs, constituting a complete
molecular dynamics simulation kit (SimKit) for sputtering, ion scattering 
and the like. 

Although the SimKit is a serious research tool, the various programs
are fairly easy to use, and could even find a place in an
undergraduate lab experiment. I think it would be particularly
useful for postgraduate students in SIMS who are striving to get
a feel for the physics of the technique.

No knowledge of molecular dynamics is required to use the SimKit
effectively.

The SimKit can be used to plot out trajectories in a collision
cascade, or used to extract quantitative information as specified
by the user (e.g. 'What fraction of sputtered atoms with energies 
greater than 5 eV are ejected within 20 degrees of the surface normal?').

This flexibility is achieved at the cost of introducing a query
language. (For example, sputtered atoms are characterised by
[rz > 0.0] & [pz > 0.0], i.e. above-surface atoms moving in
the positive z-direction.)

The SimKit requires a 486 or Pentium processor and at least
4 MB of RAM.

I am interested to gauge whether there is any interest out there
in the SIMS community for such a package. If so, e-mail me
(Marcus Karolewski, at: karolewski@ntuvax.ntu.ac.sg) before the
end of 1996.
