Beam delivery simulation
BDSIM is a code for particle–matter interaction studies in accelerators. BDSIM is a toolkit based on Geant4 for simulation of particle transport in accelerator beam-lines. It provides a collection of classes representing typical accelerator components, a collection of physics processes for fast tracking, procedures of run-time geometry construction, analysis routines and tools to interface it to other particle tracking codes.
A paper summarizing its main properties is Nucl. Instrum. Meth. A606:708-712,2009. Its use in simulating the CLIC beam delivery system has been demonstrated in: Phys. Rev. ST Accel. Beams 12:081001,2009. A figure from this paper is shown below:
This shows the energy deposition along the beamline of the CLIC beam delivery system from halo particles, with (red) and without (black) secondary particle production and scattering as simulated in BDSIM.
