CESR meaning in Academic & Science ?

The Cornell Electron Storage Ring (CESR, pronounced Caesar) is a particle accelerator operated by Cornell University and located 40 feet beneath a football field on their Ithaca campus. The accelerator has contributed to fundamental research in high energy physics and accelerator physics, as well as solid state physics, biology, art history and other fields through its use as a synchrotron light source. For many years, CESR held the world luminosity record for electron-positron collisions.

CESR pioneered several new accelerator techniques, including superconducting radio-frequency cavities and pretzel orbits.
