The Cornell Laboratory for Accelerator-based
Sciences and Education (CLASSE) is a particle accelerator facility located in Wilson Laboratory
on the Cornell University campus in Ithaca, NY. CLASSE formed from the merger of the Cornell
High-Energy Synchrotron Source (CHESS) and the Laboratory for Elementary-Particle Physics
(LEPP) in July 2006. Ritchie Patterson is the Director of CLASSE. The Wilson Synchrotron Lab, which houses both
the Cornell Electron Storage Ring (CESR) and CHESS, is named after Robert R. Wilson, known
for his work as a group leader in the Manhattan Project, for being the first director of the
Fermi National Accelerator Laboratory, and for contributing to the design of CESR.==LEPP==
The Laboratory for Elementary-Particle Physics (LEPP) is a high-energy physics laboratory
studying fundamental particles and their interactions. In operation below the athletic fields on
campus is the 768 meter Cornell Electron Storage Ring (CESR). CESR is an electron-positron collider operating
at a center-of-mass energy in the range of 3.5-12 GeV. Completed in 1979, CESR stores beams accelerated
by the Cornell Synchrotron.Adding to a long history of significant developments, such
as superconducting radio frequency cavities and pretzel orbits, the accelerator group
is now developing an entirely new type of superconducting linear accelerator called
the Energy Recovery Linear accelerator (ERL). The group is also involved in the design of
damping rings, tracking simulations, RF cavities, and accelerator operation for the International
Linear Collider (ILC). Cornell University has the largest graduate
program in accelerator physics in the US.==CHESS==
The Cornell High-Energy Synchrotron Source (CHESS) is a high-intensity, high-energy X-ray
light source. The lab provides synchrotron radiation facilities
for multidisciplinary scientific research, with a particular focus on protein crystallographic
studies under the auspices of the National Institutes of Health (NIH). CHESS was built between 1978 and 1980 as a
synchrotron x-ray facility tied to the Cornell Electron Storage Ring (CESR) High-Energy Physics
program (sometimes referred to, and better known as, particle physics), which produces
an electron energy of 5.5 GeV.The original laboratory, CHESS West, included 3 instrumented
beamlines [with] 6 independent experimental stations. The CHESS East laboratory was constructed
during 1988-1989, adding 2 beam lines and 4 instrumented experimental stations. CHESS East contains a biohazard level BL3
facility (built with funds from the NIH). Construction began in 1999 for an addition
to the facility called the “G-line” to provide a new beam line and three additional experimental
stations. This station, commissioned in 2002, was “constructed
with extensive toxic gas handling capabilities advancing the prospects for in-situ crystal
growth experiments.”Work performed at CHESS and at the National Synchrotron Light Source
(NSLS) at Brookhaven National Laboratory led to the 2003 Nobel Prize in Chemistry, awarded
to Dr. Roderick MacKinnon, M.D “for structural and mechanistic studies of ion channels
