EDDA Simulation

SIGI Home Page

SIGI is a program for simulation of passage of particles through matter. The original goal was to simulate the EDDA-experiment. But today we've got a tool that allows even more - in principle simulations of any kind of experiment in particle physics though it is best suited at intermediate energies.

With SIGI you can run your own simulation calculations by simply editing a text file - we call it ini file - that contains information on beam, target and of course geometry and metrial data of detectors, beam pipe etc. This is sufficient for many simulation tasks. Advanced problems may be attacked by overwriting the C++ code using OOP techniques - especially inheritance.

SIGI is based on the C++ class library HEPGISMO, which is Toby Burnett's version of SLAC's GISMO using the CLHEP class library. It provides a framework for simulation of passage of particles through matter. Lately, HepGismo and Gismo 0.5 have been merged and are available as Gismo 2.0.

We added the ini file formalism and implemented a new hadronic event generator and shower code called MICRES. Click here to copy a stand alone version of it. Since GISMO uses the EGS4 code for electromagnetic transport calculations, you need PEGS4 - preprocessor to EGS4 - to create new material data files. We translated the original MORTRAN code into FORTRAN. Click here to get a copy of it.

A complete SIGI documentation is under construction. Diploma and doctoral theses dealing with simulations of the EDDA-detector can be found here.
