NUMIS

NUMIS, Northwestern University Multislice and Imaging Software is a copyrighted set of programs dedicated to run on Apollo computers, and includes the Semper 6 software, a set of programs to interface to an Imaging Technology Framestore, and multislice and imaging programs.

A very simple example is shown below, a simulation of TiO2 (rutile) for as a function of thickness (across) and defocus (down) for conditions typical of the H-9000 at Northwestern.

Currently under development is a modification of these programs that will be called X-NUMIS that will be a freeware X-windows system for multislice and imaging (the Semper software is independently licensed by Synoptics Ltd).
