Full cost recovery is required for proprietary work. – The facility provides resources sufficient for users to conduct work safely and efficiently. – The facility supports a formal user organization to represent the users and facilitate sharing of information, forming collaborations, and organizing research efforts among users. – The facility capability does not compete with an available private sector capability. https://www.energy.gov/science/science-innovation/office-science-user-facilities https://science.osti.gov/User-Facilities https://science.osti.gov/User-Facilities/User-Facilities-at-a-Glance/BES 3 3 FY 2021 28 Scientific User Facilities 36,000+ users OLCF ALCF NERSC ESnet EMSL ARM JGI SNS HFIR ALS APS LCLS NSLS-II SSRL CFN CINT CNM CNMS TMF DIII-D NSTX-U FACET ATF Fermilab AC CEBAF ATLAS RHIC FRIB 4 4 Basic Energy Sciences Light and Neutron Sources Spectroscopy of Spectroscopy for Nanoscale structure Electronic Structure, Magnetic structure composition and and strain excitations chemical state National Synchrotron Light Source II Linac Coherent Light Source Stanford Synchrotron Radiation Light Source Brookhaven National Laboratory SLAC SLAC Spallation Neutron Source High Flux Isotope Reactor Advance Light Source, Advanced Photon Source Oak Ridge National Laboratory Oak Ridge National Laboratory Lawrence Berkeley National Laboratory Argonne National Laboratory 5 BES Nanoscale Science Research Centers Electron Optical microscopy Scanning Materials Nanofabrication spectroscopy for materials probes synthesis characterization Center for Integrated Nano Technologies The Molecular Foundry Sandia, Los Alamos Lawrence Berkeley Laboratory Center for Functional Nanomaterials Center for Nanophase Materials Science Center for Nanoscale Materials Brookhaven National Laboratory Oak Ridge National Laboratory Argonne National Laboratory 6 Accessing BES User Facilities § Prospective user submits a proposal to facility • Proposals are typically short – 3-5 pages – describing importance of proposed work, estimate of time required to complete work, requested beamline/instrument • Life of the proposal typically 1-2 years (depending on facility) or a 1-time experiment (sometimes called rapid-access proposals) • Proposal can be non-proprietary (no user fees) or proprietary (user fees applied) § Proposal goes through review process managed by facility • Proposals are evaluated on feasibility and merit of proposed work – criteria set by individual user facility • May be different review processes for different types of proposals (e.g., proprietary, non-proprietary proposals, rapid access, etc.) § Successful proposals are allocated time on requested beamline/instrument 7 Requirements Before/After the Experiment § Before start of experiment: • All users must have a completed User Agreement between their home institution and the facility – 2 types of User Agreements – proprietary and non-proprietary • A Safety Form is submitted by PI describing any hazards associated with experiment and any hazard mitigations (if necessary), and approved by facility representatives • All users associated with experiment must have completed facility’s required training § After completion of experiment: • Users acknowledge use of facility in any publications resulting from data obtained from access to facility • Users notify facility of those publications 8 DOE’s Light Source Network Impact by the Numbers Product breakthroughs: • ~ 11,000 users each year HIV & cancer drugs, green refrigerants, improved • From all 50 states, ~33 countries LEDs, green energy, thin films, batteries, gasoline • Oversubscribed by factor of 3 or 4 injector system • More than 250 universities • More than 200 companies, many Fortune 500 Government partnerships: • 4 Nobel Prizes DOE, NIST, NSF, NIH, NNSA, DOD, NASA Storage Rings Soft(est) X-Rays Intermediate Wavelength Hard X-Rays X-Ray Lasers Surface chemistry and Diverse range of Studies of real materials, Full spatial coherence, electronic structure characterization and systems, and processes in real ultrafast dynamics in exploration time under real conditions molecules and materials ALS NSLS-II & SSRL APS LCLS Each has unique characteristics as well as tailored overlap of certain capabilities, to cover the entire discovery space for a broad user base The Advanced Light Source at Lawrence Berkeley National Laboratory The ALS uses photons from the infrared to the hard x-ray to investigate the coupling between structure, electronic, magnetic, and lattice properties that are fundamental characteristics of quantum coherent systems, and the interaction of materials with their environments through study of temperature and field-dependence.
