摘要：
The upgrade of the LHCb experiment, planned for 2018, will transform the entire readout to a ti iggerless system being read out at 40 MHz. The upgraded silicon vertex detector (VELO) must be light weight, radiation hard, and compatible with [NC vacuum requirements. It must be capable of fast pattern recognition, fast track reconstruction and high precision vertexing. This challenge is being met with a new VELO design based on hybrid pixel detectors positioned to within 5 min of the [NC colliding beams. The detector will be shielded from the beam by a similar to 300 mu m thick aluminium foil. Evaporative CO2 coolant circulating in micro-channels embedded in a thin silicon substrate will be used for cooling. (C) 2014 Published by Elsevier B.V.
