The operation and performance of the semiconductor tracker during the first years of LHC running are described. More than 99% of the detector modules were operational during this period, with an average intrinsic hit efficiency of (99.74 +/- 0.04)%. The evolution of the noise occupancy is discussed, and measurements of the Lorentz angle, delta-ray production and energy loss presented. The alignment of the detector is found to be stable at the few-micron level over long periods of time. Radiation damage measurements, which include the evolution of detector leakage currents, are found to be consistent with predictions and are used in the verification of radiation background simulations. %K Solid state detectors %K Charge transport and multiplication in solid media %K Particle tracking detectors (Solid-state detectors) %K Detector modelling and simulations I (interaction of radiation with matter %K interaction of photons with matter %K interaction of hadrons with matter %K etc) %R 10.1088/1748-0221/9/08/P08009 %U http://arxiv.org/abs/arXiv:1404.7473 %U https://doi.org/10.1088/1748-0221/9/08/P08009 %P P08009 - 73pp
