COMGEANT simulation
General information
The COMGEANT Monte-Carlo program
is an interface to GEANT3.21
program which is a currently frozen version of the CERN simulation package
GEANT.
COMGEANT can simulate various hadron
and lepton-induced interactions and contains tools to define the detector
geometry and all other parameters using data files, without
recompiling the code.
It was used for experiment WA-89 on Omega spectrometer
and is being used for experiment
COMPASS
at CERN.
It used at the moment at TJNAF for
the Moeller polarimeter at Hall-A,
for experiment E158
at SLAC and for various other projects in Hall A, like the 12-GeV upgrade.
Since 1998 the versions at JLab and CERN started diverging and by now
may have become different species.

Status of the code
The code is stored in
CVS
format.
At the moment the repository is only at CERN. At JLAB there is a checked-out copy from Jan,1998
which now lives a life separate from the CERN version.
News
- 10 Mar 1999
New modifications: Mott scattering, radiation losses of the beam particle
in the target are included. Some problems with LEPTO are fixed.
- 09 Jul 2001
Many features have been added:
- Cherenkov photons production and tracking
- Radiative Mott
- Bhabha scattering and Compton scattering
- Generalized magnet definition
In order to simulate Cherenkov
photons production and propagation one has to define (in FFREAD)
the optical parameters of the relevant media.
