Geant4-Based Simulation Study Of Pep-Ii Beam Backgrounds In The Babar Detector At The Slag B-Factory
2005 IEEE PARTICLE ACCELERATOR CONFERENCE (PAC), VOLS 1-4(2005)
摘要
To improve the understanding of accelerator-induced backgrounds at the SLAC B-Factory, we simulate lost particle backgrounds in the BABAR detector originating from beam-gas interactions and radiative Bhabha scatters. We have extended the GEANT4-based BABAR detector simulation to include beam-line components and magnetic fields up to 8.5 m away from the interaction point. We describe the simulation model and then compare preliminary predicted background levels with measurements from dedicated single- and colliding-beam experiments.
