CHESS - Cornell High Energy Synchrotron Source (http://www.chess.cornell.edu) and LEPP - Laboratory for Elementary-Particle Physics (http://www.lns.cornell.edu) has joined to become CLASSE - Cornell Laboratory for Accelerator-based Sciences and Education.

Cornell High Energy Synchrotron Souce is a user-oriented National Facility to provide state-of-the-art synchrotron radiation facilities to the scientific community. CLASSE encompasses a multifaceted research and development program which is partly in-house and partly collaborative, with a wide spectrum of experimental groups from Universities, National Laboratories and Industry.

A special NIH Research Resource, called MacCHESS, supports special facilities for protein crystallographic studies.

Each year, 500-600 scientists, graduate and undergraduate students visit CHESS to collect data. In addition, a significant effort of the staff is aimed at developing synchrotron radiation experimental facilities and methods that utilize the high intensity photon flux provided by the Cornell Electron Storage Ring - CESR.

Cornell's Laboratory for Elementary-Particle Physics studies nature's fundamental particles and the laws that govern them. These studies shed light on questions like: how did the universe evolve? What is the nature of space and time? What, really, is mass?
LEPP physicists also develop the technology behind accelerators, which are our central window onto nature at its tiniest and are a vital tool for other sciences that explore nature at the scale of atoms and molecules.
LEPP communicates widely about its research in order to deepen public understanding of the physical sciences, improve scientific literacy, and share the excitement of discovery.
