Speaker: Martijn Mulders (CERN)

Title: "First Data in CMS"

Abstract:
In November 2009 the Large Hadron Collider at CERN produced proton-proton collisions for the first time, after many years of preparation. This talk will discuss the readiness of the CMS experiment for data taking during the start-up phase. To commission the detector and the software for data taking and analysis, the CMS collaboration has performed detailed studies of the detector performance using beam-induced and cosmic-ray muons recorded in 2008. These studies have led to an excellent understanding of the magnetic field, alignment of the silicon tracker and muon chambers, and the response and operation of the calorimeters. The talk will start with an overview of recent commissioning results followed by a preliminary look at the first data from collisions.
