Explore the ATLAS Experiment at CERN in this 360° guided tour with particle physicist Dr. Sascha Mehlhase! This full-length tour recreates a public tour of the ATLAS Experiment, while also taking you to parts of the cavern only accessible to engineers. This is a unique opportunity to explore the experiment with an expert, who explains the physics and engineering behind this mammoth detector. Dr. Mehlhase will point out the most interesting features that can only be seen from the cavern, while also discussing the 5000+ person collaboration that keeps ATLAS running! ATLAS is the largest volume detector ever constructed for a particle collider: 46m long, 25m in diameter, and sitting in a cavern 100m below ground. ATLAS weighs 7,000 tonnes, similar to the weight of the Eiffel Tower. ATLAS is a many-layered instrument designed to detect some of the tiniest yet most energetic particles ever created on earth. It consists of six different detecting subsystems wrapped concentrically in layers around the collision point to record the trajectory, momentum, and energy of particles, allowing them to be individually identified and measured. A huge magnet system bends the paths of the charged particles so that their momenta can be measured as precisely as possible. This tour was recorded on 13 February 2020, prior to CERN's partial shutdown due the global COVID-19 situation. Visits to ATLAS and CERN are currently suspended, though we invite you to visit us in person at a future date.
