Full characterisation of a BGV fibre module (4-layer) at the SPS test beam

A spare tracking module (4 fibre layers) of the BGV detector was tested in the experimental setup of the LHCb SciFi tracker test beam at SPS. A telescope was placed upstream the module in order to reconstruct the track of particles. A detailed analysis of the hit resolution and hit detection efficiency of the module as well as the influence of the cluster thresholds is available in this document: TestBeamReport. With optimal thresholds, the hit resolution is measured to be σ hit = 38.2 2.8 μm and σ hit =42.9 3.9 μm for the two sides of the module, whereas the efficiency is ε hit = 98.3% and ε hit = 97.8%.
