This article first appeared in the 2019 Physics World Focus on Instruments & Vacuum.

The Large Hadron Collider is known for discovering the Higgs boson, but the technologies used in accelerating and detecting new particles also have uses outside of high-energy physics. Carsten Welsch explains how technology transfer is creating a new generation of compact accelerators with applications ranging from security to cancer treatment

The Large Hadron Collider uses radiofrequency cavities to accelerate particles and keep them in controlled bunches.
