摘要
The CMS detector at the Large Hadron Collider (LHC) is a very complex apparatus with more than 70 million acquisition channels. To exploit its full physics potential, a very careful calibration of the various components, together with an optimal knowledge of their position in space, is essential. The CMS Collaboration has set up a powerful offline infrastructure to allow for the best knowledge of these conditions at any given moment, thus following as quickly as possible any change in running conditions. This paper reviews the design of this framework and reports the experience gained in the first period of data taking.
