* Users are researchers who propose and conduct peer-reviewed experiments at a scientific facility. • The primary type of user is a Badged User, i.e., a researcher who conducts experiments within the facility. • There are two other types of users who conduct experiments: (1) Remote User—a researcher who has been granted authority to remotely produce data (this excludes persons who can “look at data”); and (2) Off-Site User—a researcher to whom the facility provides custom-manufactured materials, tools, or devices that the facility has unique or unusual capabilities to fabricate (this applies only to such activities at Nanoscale Science Research Centers). For both types of these users, only one user is to be counted per proposal regardless of the number of co-investigators, and only if no individual is counted in any of the other user categories under the same proposal. • For annual totals, an individual is counted as 1 user at a particular facility no matter how often or how long the researcher conducts experiments at the facility during the fiscal year. A Badged User cannot also be counted as another type of user. Users must submit a successful, peer-reviewed research proposal and conduct experiments, as described above. Therefore, users do not include individuals who only send in samples to be analyzed, even if such activities are part of a peer-reviewed experiment. Users do not include individuals who pay to have specialty services performed or visit the facility for tours or educational purposes. Users also do not include researchers who collaborate on the proposal or subsequent research papers but do not conduct experiments at the facility.

^aHFIR was down for maintenance, safety standowns, and upgrades for significant periods during FY01–FY06. HFIR's users include researchers who perform neutron scattering (figures shown above). HFIR also delivers services such as neutron activation analyses and materials irradiation.
^bThe IPNS closed in January 2008. The facility started to identify remote users in FY 2005 (153, FY05; 117, FY06; and 55, FY07; not included in above table).
^cThe Center for Microanalysis of Materials at the University of Illinois was designated a BES user facility prior to FY 2006.
^dNumbers of users are reported for the Nanoscale Science Research Centers starting with the fiscal year in which each facility first received full operational funding.
^eThe Combustion Research Facility at the Sandia National Laboratory, Livermore CA will no longer be a designated BES user facility in FY 2009.
^f The Materials Preparation Center and the research facilities within the Notre Dame Radiation Laboratory were designated BES user facilities prior to FY 2008.
^gThe James R. Macdonald Laboratory was designated a BES user facility prior to FY 2004.
^hThe Surface Modification and Characterization Center was designated a BES user facility prior to FY 2002.
