Today proton-proton collisions for physics restarted again after a 5 month “Extended Year End Technical Stop”. This traditional winter shut-down period was “extended” due to major installation work carried out in another one of the LHC detectors. The recommissioning of the accelerator has proceeded very smoothly and first collisions arrived earlier than initially expected. During the technical stop LHCb performed relatively minor maintenance work on the detector, and, on the other hand, major interventions on the access lift and the crane in the underground cavern. The LHCb detector and its data acquisition system are ready for a bumper year of data taking that will allow the experiment to obtain even more precise and interesting physics results. The image displays a typical event recorded today.
