Simulation of the light yield attenuation maps for the LHCb SciFi Tracker Upgrade

The Scintillating Fibre (SciFi) Tracker will replace the Inner and Outer Tracker in the LHCb upgrade, to be installed in 2019-2020. It is made from thin scintillating fibres read out by multichannel Silicon Photomultipliers (SiPM). The number of photons reaching the SiPMs depends on the path length...

Sumario:The Scintillating Fibre (SciFi) Tracker will replace the Inner and Outer Tracker in the LHCb upgrade, to be installed in 2019-2020. It is made from thin scintillating fibres read out by multichannel Silicon Photomultipliers (SiPM). The number of photons reaching the SiPMs depends on the path length of the photons in the fibre and the amount of radiation damage suffered by the fibre. A detailed single fibre simulation in GEANT4 is used to produce maps which give the expected mean light loss for different hit positions in the SciFi detector. The simulation of these maps is described in this note.
