SNS/BNL Diagnostics System Group


The Spallation Neutron Source project is a collaboration between six national laboratories of the United states to build a Mega Watt neutrons source driven by a proton accelerator. The complex is going to be build in Oak Ridge (Tennessee) and consists of a full energy (1 Gev) linac, an accumulator ring and a mercury target with several instruments for neutron scattering. Information on the project can be found at

At Brookhaven National Laboratory we work mainly on the accumulator ring and transfer lines diagnostics (HEBT, Ring, RTBT). Some of the systems are SNS-wide ie: the Beam Loss Monitor system and Beam Current Monitor system. In addition our group provides parts of other systems to our partner laboratories. Our group is part or the Collider Accelerator Division that is also in charge of RHIC and the AGS complex.  If you are looking for information on a particular topic you can contact the persons working on it.

DOE, Office of Science One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
