CMS experiment at the LHC: Commissioning and early physics

Understand

The CMS collaboration used the past year to greatly improve the level of detector readiness for the first collisions data.

• The acquired operational experience over this year, large gains in understanding the detector and improved preparedness for early physics will be instrumental in minimizing the time from the first collisions to first LHC physics.
• The following describes the status of the CMS experiment and outlines early physics plans with the first LHC data.
