Introduction

GSTAR is a framework designed for the STAR detector simulation using the GEANT simulation package. The simulation program is an enhanced version of the interactive GEANT (GPAW), controled via KUIP interface.  The GSTAR package consists of a set of .g modules (text files), each providing description of the:
  • geometry of different subsystems of the STAR detector , like Beam pipe, Silicon Vertex Tracker, TPC etc...
  • procedure to perform operations like i/o, particle generation, on-flight analysis etc. under user control.
GSTAR accepts interactive commands or KUIP kumac files. There are few examples of kumac files in $STAR/kumacs/sim directory. Among these, have a look in the material.kumac - it allows to get material distribution plots in any STAR subsystem or combination of subsystems. GSTAR accepts different types of input files. GSTAR produces output in a file, which have a platform independent FZ format. The content of FZ files can be read as tables in STAF by the G2T module, or in ROOT.
