The crystal story
A crystal’s journey from creation to its place within the CMS electromagnetic calorimeter is an arduous one: its trials include travelling thousands of miles, being sawed and polished, as well as being heated to 1,165oC and cooled to 18oC.

ECAL Preshower
One way the Higgs boson might decay is into high-energy photons and detecting them is one of the ECAL’s primary functions.

Crystal Calorimeter
CMS uses lead tungstate (PbWO4) for the almost 80,000 crystals: a material with high density that produces scintillation light in fast, small, well-defined photon showers.

Why is CMS so big?
It may seem strange that to record the Universe’s tiniest constituents we need the world’s most powerful machines and detectors.

How CMS detects particles
Each particle that emerges from an LHC collision is like a piece of a puzzle, with some of these pieces breaking up further as they travel away from the collision.
