The Large Hadron Collider will provide an unprecedented quantity of collision data right from the start-up. The challenge for the LHC experiments is the quick use of these data for the final commissioning of the detectors, including calibration, alignment, measuring of detector and trigger efficiencies. A new energy frontier will open up, and measurement of basic Standard Model processes will build a solid basement for any discovery studies.The Large Hadron Collider will provide an unprecedented quantity of collision data right from the start-up.
