The Cornell High Energy Synchrotron Source (CHESS) is a user-oriented National Facility to provide state-of-the-art synchrotron radiation facilities to the scientific community. Supported by grants from the Division of Materials Research of the National Science Foundation, CHESS 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. Each year, 400-500 scientists and scientists in training visit CHESS to collect data that comprises all or part of their research programs. Also, 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).
CHESS was constructed in the period from 1978 to 1980 as a synchrotron
x-ray facility parasitic to the CESR High Energy Physics program. The
original laboratory, CHESS West, included 3 instrumented beam lines, A,
B, and C that provided 6 independent experimental stations. The total
experimental West area is about 1000 square feet. The CHESS East
laboratory was constructed during 1988-1989, adding 2 beam lines, D and
F, and 4 instrumented experimental stations. CHESS East contains a
biohazard level BL3 facility (built with funds from the NIH) which is
part of the F1 station.
Construction began in 1999 for an addition to the facility through funds
provided by Cornell University. This new addition is to be the home to
the new G-line and associated 3 additional experimental stations which
are being constructed with a grant from the NSF. The new facility will
be operated in conjunction with CHESS by a Cornell University consortium
to provide additional capabilities for experimenters. The new G3 station
is being constructed with extensive toxic gas handling capabilities
advancing the prospects for in-situ crystal growth experiments.
Other facilities include a well-equipped modern darkroom, cold room for
crystal mounting, experimental laboratories for user set-up, a central
computer facility, and a machine shop with two resident machinists.
There are general areas for setting up experiments which include a
chemical room with fume hood as well as user accessible shop facilities.
A user lounge is available to help make a long 24 hour day a bit more
tractable.
