What are the detectors at the LHC?

There are seven experiments installed at the LHC: A Large Ion Collider Experiment (ALICE), A Toroidal LHC ApparatuS (ATLAS), the Compact Muon Solenoid (CMS), the Large Hadron Collider beauty (LHCb) experiment, the Large Hadron Collider forward (LHCf) experiment, the TOTal Elastic and diffractive cross section Measurement (TOTEM) experiment, and Monopole and Exotics Detector at the LHC (MoEDAL). ALICE, ATLAS, CMS, and LHCb are big experiments installed in four huge underground caverns built around the four collision points of the LHC beams. TOTEM is installed close to the CMS interaction point, LHCf is installed near ATLAS, and MoEDAL is close to the LHCb detector.
