Long Term Studies of the Tracking Efficiency for the LHCb SciFi-Tracker — •Holger Stevens and Martin Bieker — Experimentelle Physik 5, TU Dortmund

The LHCb-Detector is upgraded in the ongoing shutdown of the Large Hadron Collider. Among other things the tracking stations will be replaced by the so called SciFi-Tracker. This tracker is made of scintillating fibres.

The light output of the fibres decreses during the life time of the detector, which is caused by two major factors. On the one hand the irradiation of the fibres caused by the operation of the LHC. On the other hand natural aging of the material.

This talk will show possibilities to simulate these effects and estimate the tracking efficiency of the Scifi-Tracker during the planed data taking period of 10 years.
