General Descriptions

The official Monte-Carlo program to simulate the BNL E949 experiment is based on EGS4 (sorry, not on GEANT) and is called UMC ("Unified Monte Carlo"). UMC has been developed and maintained by the BNL E787 collaboration, since 1980's, upto the version6. The UMC version7 is for E949 and takes care of the new detector with Barrel Veto Liner officially.

• To treat energy deposition by photons and electrons, routines from EGS4 are used.
• For heavy charged particles as pions and muons, the energy deposition is calculated by adding the energy losses of each ionization and excitation events along the steps taken by the particules using the Bethe-Bloch formula.
