The Bio-SANS Small-Angle Neutron Scattering Instrument at Oak Ridge National Laboratory

Abstract

Oak Ridge National Laboratory (ORNL) has completed the High Flux Isotope Reactor (HFIR) Scientific Facilities Upgrades Project that included installation of a new, high-performance cold source on HB-4 and the construction of a new guide hall at the 85 MW reactor. Two new SANS instruments are served by the cold source: the Bio-SANS instrument, a 35-m SANS instrument dedicated to the study of biological systems (Figure 1), and its sister instrument, the 40-m high-resolution SANS. The performance of these instruments will rival the world's best. The Center for Structural Molecular Biology (CSMB) has been established at ORNL to support and develop the user research and science programs on the Bio-SANS instrument, as well as the neutron sciences for biology at HFIR and at the Spallation Neutron Source (SNS).
