Experiment

  • Posted on: 18 July 2014

ALICE is a 10,000-tons detector – 26 m long, 16 m high, and 16 m wide. It sits in a vast cavern 56 m below ground in the terittory of Sergy on the border with St Genis-Pouilly in France.  The detecor is designed to measure, in the most complete way possible, the particles produced in the collisions which take place at its centre, so that the evolution of the system produced during these collisions can be reconstructed and studied. To do so, many different subdetectors have to be used, each providing a different piece of information. To understand such a complex system, one needs to observe it from different points of view, using different instruments at the same time, in the same way that a satellite looks at the earth combining detectors sensitive to different wavelength, which, allow us to see forests or clouds or archeological sites…
