CLAS detector at the center of CLAS. These collisions generally produce new particles, often after the target nucleons (protons and neutrons) are briefly excited to heavier-mass versions of the familiar protons and neutrons. A whole variety of intermediate-mass short-lived particles called "mesons" can be created. Scattered electron as well as the longer-lived produced particles travel through the CLAS detector, where they are measured. Particle physicists use these measurements to deduce the underlying structure of protons and neutrons and to better understand the interactions that create these new particles. The CLAS detector system was operational from 1998 until May 2012. From that time
