Irene Degl'Innocenti: This Engineer Keeps CERN's Particle Accelerators on Track

The Large Hadron Collider has transformed our understanding of physics since it began operating in 2008, enabling researchers to investigate the fundamental building blocks of the universe. Some 100 meters below the border between France and Switzerland, particles accelerate along the LHC's 27-kilometer circumference, nearly reaching the speed of light before smashing together.
