The Monte Carlo simulation of the Borexino detector

Understand

We describe the Monte Carlo (MC) simulation package of the Borexino detector and discuss the agreement of its output with data.

• The Borexino MC 'ab initio' simulates the energy loss of particles in all detector components and generates the resulting scintillation photons and their propagation within the liquid scintillator volume.
• The simulation accounts for absorption, reemission, and scattering of the optical photons and tracks them until they either are absorbed or reach the photocathode of one of the photomultiplier tubes.
• Photon detection is followed by a comprehensive simulation of the readout electronics response.
