The first stage in
simulating the PHENIX detector is the program "PISA"
which tracks
particles produced by the event generators. The output from PISA is
something called a "hits file" which is a collection of event-by-event
data produced as the tracked particles pass through the sensitive parts
of each detector subsystem. The following link is for Documentation for
PHENIX Simulation Software at Vanderbilt.
For detail description of
how to run PISA, please follow the link to PISA Primer manual.

Events Generations:
There are almost an unlimited number of ways of generating events to
track in PHENIX simulation software, PISA. Specifically there are 24
different event generator interfaces supported in PISA. Event
generators may be thought of as being internally computed or externally
computed via stand-alone programs. Examples of internal event
generators are those for single particle tracking, dual particle
tracking, or resonance decay tracking. There is even an internal "full
event" generator called UA1 which mimics the pion spectra of real event
generators. The full external event generators HIJET, HIJING,
VENUS, RQMD, LUCIAE, VNI, PYTHIA
and EXODUS have their interfaces available with PISA. In almost all
simulation studies for nucleus-nucleus collision, HIJING has been used
as the default full event generator in PHENIX whereas PHYTHIA is most
commonly in use for proton-proton collisions. For single particle event
generation EXODUS is most commonly used in PHENIX.
The Simulation group maintains the full event generator repository.
With a CVS checkout as
cvs checkout event_gen
user will get the entire event generator source code package.
The event generators can be compiled/linked on the different platforms,
but this should generally not be necessary since the binaries can be
executed over the AFS.
