Hadron Collider Completes Proton Tests

摘要

The Large Hadron Collider, which is located in Geneva and is the largest and most powerful supercollider in the world, has completed its initial three years of proton collision tests and will not resume such tests until 2015. Owned and operated by the Conseil eu-ropeen pour la recherche nucleaire (CERN)-the European Organization for Nuclear Research-the collider has been smashing protons into one another in an attempt to confirm the existence of rare particles thought to have been created in the big bang.
