Accelerators can collide particles together, but scientists need detectors to reveal what happens when they do. Fermilab has been at the forefront of detector technology for decades, working most recently on the massive CMS detector at the Large Hadron Collider in Switzerland and the next generation of neutrino detectors for experiments in the U.S. The technologies developed for these physics experiments can be applied to fields as diverse as the financial industry and medical diagnostics.
