Radiation damage in the LHCb vertex locator

Journal article

The LHCb Vertex Locator (VELO) is a silicon strip detector designed to reconstruct charged particle trajectories and vertices produced at the LHCb interaction region. During the first two years of data collection, the 84 VELO sensors have been exposed to a range of fluences up to a maximum value of approximately 45 × 1012 1 MeV neutron equivalent (1 MeV n eq). At the operational sensor temperature of approximately -7 °C, the average rate of sensor current increase is 18 μA per fb -1, in excel...
