  1. Advanced Light Source (ALS) Intense Pulsed Neutron Source (IPNS) National Synchrotron Light Source (NSLS) (NSLS-II upgrade CD-0 approved) Spallation Neutron Source (SNS) High-Flux Isotope Reactor (HFIR) DOE Synchrotron and Neutron FacilitiesWhat They Do, Why They Matter Advanced Photon Source (APS) Stanford Synchrotron Radiation Laboratory (SSRL) Los Alamos Neutron Science Center Linac Coherent Light Source (LCLS) (under construction) The Synchrotron and Neutron Users’ Group (SNUG) represents: • 4 Neutron Sources • 5 Photon Light Sources • Including one under construction Page 1

  2. Who We Are The Synchrotron and Neutron Users’ Group (SNUG) represents over 9,000faculty,student,industrialandgovernmentscientists. Their research is critical to every sector of the economy: • Materials Chemistry and Nanotechnology • Electronic Materials and Devices • Energy Production, Storage and Conversion • National Security • New Medicines and Disease Treatments • Environmental Sciences • Human and Molecular Biology • These scientists are from all over the USA • Their work is critical to American Competitiveness Page 2

  3. Who We Are Approximately 600 scientists from over 160 companies representing technology, manufacturing, energy, chemical, and bio-pharmaceutical industries use the synchrotron and neutron facilities. Page 3

  4. Neutrons: are uncharged, so they can penetrate deep into materials to give precise information about positions and motions of atoms in the interior of a sample. are particularly well-suited to study the magnetic structure and properties of materials. are especially sensitive to the presence of light elements such as hydrogen, carbon, and oxygen which are found in many biological molecules. Synchrotrons: produce ultra-high intensity light over a wide range of energies frominfra-redto visible lightto ultraviolet to X-rays. the energy of this light can be precisely tuned allowing many different kinds of element-specific investigations, such as: determining atomic scale and nanoscale STRUCTURE in proteins, semiconductors, and nanoparticles; determining the MECHANISM by which superconductors work, cells respire, diseases infect, and catalysts operate; or ANALYZING and IDENTIFYINGtrace quantities of harmful substances in lakes, oceans, air, soils, or human tissues. WHY Are These Machines So Valuable? The federal government is uniquely capable to design, build and operate facilities large and sophisticated enough to be of continuing use to thousands of individual industry and government researchers.

  5. A Significant and Dramatic increase in our fundamental science output is due to our synchrotron and neutron sources Scientists use the DOE synchrotron and neutron facilities in ever-increasing numbers. FISCAL YEAR A fully funded Office of Science budgetof 4.4 billionwould begin to restore more efficient use of this national investment, and greatly increase support for peer-reviewed research into energy efficiency and supply, toxic waste clean up, bio-terrorism and disease detection, electronics, telecommunications, and manufacturing.

  6. The synchrotrons and neutron sources were invented out of fundamental physics at U.S. laboratories. The U.S. now has 8 major facilities. The FY 2008 budget and continued strong funding will augment current U.S. capacity with 1 additional facility and another major upgrade. While the U.S. invented these machines, in recent years other nations of the world have hastened to build their own 10 synchrotrons worldwide in 1980 >50 synchrotrons worldwide today, with more under construction Major construction of neutron sources underway in Europe and Japan Competition for Synchrotron and Neutron Sources Considering only beam ports on 3rd generation synchrotrons worldwide, by 2009 the U.S. will be outnumbered by the rest of the world 7:1 Page 6
