  The LHCb experiment is designed to perform high-precision measurements of CP
violation and search for New Physics using the enormous flux involving beauty
and charm quarks produced at the LHC. The operation and the results obtained
from the data collected in 2010 and 2011 demonstrate that the detector is
robust and functioning very well. However, the limit of 1 fb^-1 of data per
nominal year cannot be overcome without improving the detector. We therefore
plan for an upgraded spectrometer by 2018 with a 40 MHz readout and a much more
flexible software-based triggering system that will increase the data rate as
well as the efficiency specially in the hadronic channels. Here we present the
LHCb detector upgrade plans, based on the Letter of Intent and Framework
Technical Design Report.
