Cornell Electron Storage Ring

The project was led by Cornell physicist Maury Tigner who devised a "fiendishly clever" method of filling the ring with positrons generated by the synchrotron.

From this point on, the accelerator provided a reliable beam of high energy electrons and positrons to the CLEO and CUSB particle detectors.

This turned out to be ideal for the study of the B meson and data from these collisions provided physicists with many new insights into the physics of fundamental particles.

CESR installed sets of wiggler magnets in the early 2000s to allow operation at lower energies for the CLEO-c project.

This NSF user facility is one of only five in the world that can generate the high energy x-rays needed for research in fields such as solid state physics, biology, material science, art history, among others.
