Image of the Week: Down the Rabbit Hole Seven elements of the High Momentum Particle Identification Detector are set up on a platform before insertion inside ALICE’s octogonal magnet structure. Image courtesy of CERN ALICE, A Large Ion Collider Experiment, is one of five experiments preparing to receive data from the Large Hadron Collider at CERN starting in 2008. ALICE is a nuclear physics experiment built to study the nature of the quark-gluon plasma. Scientists consider the quark-gluon plasma to be a fundamental key to understanding both the basic structure of ordinary matter and the birth of matter in the early universe. The ALICE collaboration involves more than 1,000 physicists, engineers and technicians from 30 countries, and will use the services and collaborating grid infrastructures of the Worldwide LHC Computing Grid to provide experimental data to its members.

This Flash animation tracks the data that will be produced by the Large Hadron Collider particle physics experiments, from their origin in collisions 100 meters underground to the laptops of scientists all over the world. The animation, developed at CERN, the European Organization for Nuclear Research, includes an introduction to computing for particle physics experiments and to the Worldwide LHC Computing Grid.
