CMS Alignment and Calibration

Abstract content

Determination of alignment and calibration constants plays one of the central role in the operation of the CMS experiment. Prompt and accurate alignment and calibration of the CMS components are crucial to achieve optimal performance of the detector and to allow the CMS physics program to reach its goals. Sophisticated algorithms and workflows are developed and routinely employed to align and calibrate various systems of the CMS detector. Also dedicated express streams of promptly reconstructed data events with reduced content have been deployed to achieve fast access to data samples after collection and their efficient processing in alignment and calibration workflows. We discuss details of the alignment and calibration procedures for all CMS components, results of the several years of CMS operation and achieved performance of the CMS detector for physics analyses. We also present plans for upgrade and future development.
