Cornell accelerator physicists pursue a broad range of topics in accelerator science and technology. From the operation of the on-campus Cornell Electron Storage Ring (CESR), to the construction of an innovative new x-ray light-source and the design and construction of future high energy colliders, students at Cornell have a unique opportunity to "drive" existing accelerators and design new ones.

For over 20 years, CESR has been a world class collider for particle physics and a powerful x-ray source. It has been the site of numerous innovations in accelerator technology, and has made Cornell a laboratory that is rich in history, technologically advanced, and internationally acclaimed for accelerator physics.

The accelerator group is now developing an entirely new type of superconducting linear accelerator that would be built at Cornell. This machine, the Energy Recovery Linear accelerator (ERL), features x-ray beam brilliance orders of magnitude higher than can be obtained with synchrotron sources and produces femtosecond x-ray pulses with unprecedented intensities. (Faculty: Bazarov, Hoffstaetter, Liepe, Tigner)

Cornell's accelerator group is heavily involved in the design of the International Linear Collider (ILC), a TeV-scale electron-positron collider proposed for construction and operation in the next decade. Cornell is contributing to research and development projects for the ILC damping rings, tracking simulations, RF cavities, and accelerator operation. Cornell accelerator physicists plan to operate CESR as an experimental test accelerator for the ILC damping ring beginning in early 2008. (Faculty: Rubin, Dugan, Hartill, Tigner)

Cornell is a major site for developing superconducting cavities used to accelerate beams. The Superconducting Radio-Frequency group has produced cavity designs that are used around the world, including cavities with world-record setting accelerating gradients. (Faculty: Liepe, Padamsee)

Cornell University has the largest graduate program in accelerator physics in the US, and is one of a few with an accerator right on campus. Cornell graduates hold leadership positions at the Laboratory for Elementary-Particle Physics, as well as many other leading accelerator laboratories in the nation and abroad, including Argonne, Fermilab, DESY, SLAC, LBL and SNS.
