LHC's ATLAS and CMS Detectors

We describe the design of the ATLAS and CMS detectors as they are being prepared to commence data-taking at CERN's Large Hadron Collider. The very high energy proton-proton collisions are meant to dissect matter and space-time itself into its primary elements and generators. The detectors by synthesizing the information from the debris of the collisions are reconstituting the interactions that took place. LHC's ATLAS and CMS experiments (and not only these) are at the closest point of answering in the lab some of the most puzzling fundamental observations in nature today.
