ATLAS (A Toroidal LHC Apparatus)
SCIPP is also participating in the engineering and technical construction of several particle detectors located around the world. The one shown above is named, ATLAS (A Toroidal LHC Apparatus). These detectors are used to discover and study the smallest components of matter, termed "elementary particles," and to learn about the forces that cause them to interact and combine.
The ATLAS experiment is being constructed by 1850 collaborators in 150 institutes around the world. It will study proton-proton interactions at the Large Hadron Collider (LHC) at the European Laboratory for Particle Physics CERN. The detector is due to begin operation in the year 2005. ATLAS is designed to improve our fundamental understanding of matter and forces. A prime physics goal of ATLAS is to understand the nature of mass.
This is the underground tunnel of the Large Hardon Collider (LHC) accelerator ring, where the proton beams are steered in a circle by magnets. The LHC is the accelerator facility (in France and Switzerland) which will contain the ATLAS detector.
