The LHCb Upgrade

The LHCb experiment, designed to perform high-precision measurements in the heavy flavor sector, has achieved results that go well beyond the expectations during the LHC run 1. The 2010-2012 data taking demonstrated that the detector and the trigger system are robust and functioning very well. The physics potential of the experiment can be extended to study very rare phenomena and to search for new physics in the heavy flavor sector only if the collected data can be increased much beyond the 1 fb$^{-1}$ per year. In order to achieve this goal detector, data acquisition and trigger must be improved. The plans for the spectrometer upgrade, the new system read-out and the new trigger are presented here together with the major physics motivations.
