Goals and Expected Outcomes

1. Showcase the important scientific research challenges that are being addressed at these Oak Ridge facilities by both users and facility scientists
2. Receive feedback on developments in next-generation instrumentation, such as
   • Developing time-resolved techniques suitable for studying non-equilibrium phenomena at microsecond timescales, e.g. in pump-probe experiments;
   • Multi-parameter sample environments (perhaps high magnetic field and high pressure and low temperature simultaneously, biological systems);
   • Multiple characterization techniques on the same instrument, such as x-ray, neutron, electron transport, and mechanical properties;
   • Computational needs and capabilities for neutron scattering and nanoscience;
   • Nanoscale synthesis and characterization; and
   • Environmental electron microscopy.
3. Acquaint current and prospective users with the research capabilities of the user facilities through presentations, tours, and workshops.
4. Introduce prospective users to the user proposal process.

Why Should I Attend?

What makes ORNL Users Week different from other scientific society events is an opportunity for speakers and attendees to provide an input to our future direction and capabilities. Sessions are designed to focus on at least one of the four goals, answering questions that would guide the future development of the SNS, HFIR, CNMS, and SHaRE capabilities. What are the exciting science topics? What new techniques take best advantage of a high-power pulsed neutron source? What are the current frontiers and limitations of the experimental capabilities? What equipment should the ORNL facilities add? What should and do our users want to do here that we should be able to do better than anyone else? Speakers are invited to specifically address these points and leave sufficient time in their talks to and solicit and receive feedback from the audience on these topics. Discussions on the neutron scattering portion will be summarized during session W2, the SHUG Meeting and Discussion Summary.  

ORNL Users Week is the first User Meeting to report on results of experiments using the newly commissioned instruments at the pulsed Spallation Neutron Source and the steady-state High Flux Isotope Reactor.  We expect interest in these facilities will dramatically increase because of the potential of these instruments and others in the design and construction phase.  This will provide an opportunity for biologists, chemists, materials scientists, and physicists to describe their needs for experimental apparatus including sample environments and new instruments.  The neutron scattering portion, SHUG2007, will provide an unprecedented opportunity both for those experienced with neutron scattering and those new to the technique to learn about the capabilities at Oak Ridge National Laboratory.  Through personal interactions between users and potential users from academia, industry, and government research laboratories and ORNL staff of these facilities, we believe this meeting will continue the enthusiasm demonstrated at previous user meetings.

ORNL staff will also solicit feedback on user processes, services, and support capabilities.

As part of this meeting:

• Tours of both the SNS, HFIR, and CNMS will be provided
• Demonstrations of the proposal system used to submit experiment proposals to these ORNL user facilities
• Poster session will highlight current research; and
• Brief workshops for new users will be held on Reflectometry, SANS, and Inelastic Scattering and Engineering

Directions to ORNL’s Conference Center and Spallation Neutron Source:
Advance registration is required.

Sessions for Users Week 2007 will be held at Oak Ridge National Laboratory, on different days at the Conference Center (building 5200) and at the Spallation Neutron Source and Center for Nanophase Materials Sciences on Chestnut Ridge.  See the forthcoming schedule for details.  A bus from the conference hotel in Oak Ridge will be the best method to come to ORNL.  The bus will return to the conference hotel at the end of each day’s sessions.  Specific times will be included on the agenda.

Attendees may drive their own vehicles to ORNL, but must allow an extra 30 minutes for processing at the security portal. For those driving take Bethel Valley Road westbound to the security portal, stop and show identification for each member in the vehicle.  Upon approval, continue westbound on Bethel Valley Road for about 3 miles to the first traffic signal.  If the day’s session is at SNS, then turn right at the signal and the large stone “Spallation Neutron Source” sign.  Proceed up the road 1.8 miles to a large flat parking area at the top of the hill, park in front of the building that has three flag poles in front of it (Building 8600).  To the right of the flag poles is the main entrance.  If the day’s session is at the ORNL Conference Center, then proceed straight ahead at the first traffic light to the roundabout and take the first right turn into the parking lot.  The Conference Center is the closest building to the parking lot across Bethel Valley Road and is also the home of the Visitor Center and the cafeteria.

Additional directions from specific locations can be found on ORNL's Driving Directions page. A McGhee Tyson Airport to Oak Ridge/ORNL/SNS route map is provided here in PDF format. Addtional maps can be found on ORNL's Getting to ORNL or Getting Around ORNL pages such as this visitor center campus map and SNS campus map also provided in PDF format.

Scholarships

A limited number of scholarships (up to $500 and waiver of registration) are available for graduate students and early career faculty at U.S. academic institutions to attend the ORNL User Meeting. These scholarships are directed to new users of nanoscience or neutron scattering techniques. To be considered for a scholarship, candidates must provide an abstract describing: their research interests and the future role they expect nanoscience or neutron scattering, or both, to have in their research, and the benefits of attending this user meeting. All candidates must provide their institution and academic department and how many years since they finished their degree (early career academics). Graduate students must provide the name and email address of their research advisor.  A poster presentation will be required for all scholarship winners; the poster will describe the candidate’s present and future research interests as summarized in the abstract and aligned with the goals of this User Meeting.  Please submit the information to Al Ekkebus, ekkebusae@ornl.gov, by September 10.

These scholarships are provided through the generosity of Oak Ridge Associated Universities and the Joint Institute for Neutron Sciences of ORNL and the University of Tennessee.

Tutorials

Neutron Scattering:

The goal of the following tutorials is to provide an initial familiarization with one of several neutron scattering techniques.  They are directed to those wishing a basic understanding of neutron scattering and each session is limited to about 10 registrants of the User Meeting.  Please enroll by checking the appropriate box on the registration page.  Please contact Al Ekkebus, ekkebusae@ornl.gov, for more details.

The topics are:

• Small angle neutron scattering: This non-destructive method for determination of microstructures with lengths between 0.5 nm and 500 nm is based on the principle that an initially parallel neutron beam is scattered by inhomogeneities of a sample. These can be due to fluctuations in density, isotopic or chemical concentration, or magnetization. This method is widely used in biological structure research (viruses, proteins, and enzymes), polymer research (conformation analysis), energy and environmental engineering (porosity and surfaces of filter materials and catalysts) and the development of materials.
  
  
• Reflectometry: Reflectometry uses neutrons scattered at grazing angles as a probe of depth-dependent composition and in-plane correlations in flat samples. By using a polarized beam, neutron reflectivity is sensitive to the magnetic, as well as the chemical, composition of samples. Examples of materials studied include magnetic nanostructures, biological membranes, and thin polymer films.
  
  
• Inelastic neutron scattering: Inelastic neutron scattering is an experimental technique commonly used in condensed matter research to study atomic and molecular motion as well as magnetic and crystal field excitations. It distinguishes itself from other neutron scattering techniques by resolving the change in kinetic energy that occurs upon a collision between neutrons and the sample is an inelastic one.
  
  
• Rietveld analysis: This technique is used to characterize structure of crystalline materials. Neutron diffraction of powder samples results in a pattern characterized by peaks in intensity at certain positions in wavelength and scattering angle. The height, width and position of these peaks can be used to determine many aspects of the materials structure.  It uses a least squares approach to refine a theoretical line profile until it matches the measured profile. The introduction of this technique was a significant step forward in the diffraction analysis of powder samples because it is able to deal reliably with strongly overlapping reflections.
  
  

Nanomaterials:

• Two-Day Workshop on Piezoresponse Force Microscopy: The 2-day course presents a combination of tutorial lectures on nanoscale and surface effects in ferroelectric and piezoelectricity and electrophysiology in biological systems, and introduces nanoscale electromechanics as an approach to address physical properties of these systems on the nanoscale. The set of tutorial lectures are given on basic principles and advanced topics in Piezoresponse Force Microscopy - a technique capable of probing electromechanics of inorganic and biological systems on the nanoscale, illustrating applications for ferroelectric, multiferroic, biological, and macromolecular systems. The full description is available here [link]. The course is complemented by the poster sessions by attendees, and three-days hand-on labs featuring Switching Spectroscopy PFM and band-excitation PFM.
  
  
• Raman spectroscopy of nanomaterials: Research opportunities and techniques using Raman spectroscopy at CNMS will be described, including:  tunable Raman microscopy characterization, resonant Raman scattering of single-wall carbon nanotubes and nanohorns, in situ pulsed Raman spectroscopy of nanomaterial synthesis, and in situ operando analysis of catalytic processes.
  
  
• Starting a nanofabrication project: This session will focus on the process of going from a structure or device concept to a point where the project is ready to be executed in the Nanofabrication Research Laboratory. The main focus will be on understanding the scope of pre-execution design, CAD, and process planning that is required for a successful user experience, and we will discuss strategies for addressing these challenges.
  
  
• Atom probe tomography: This technique enables the visualization and quantification of the 3-dimensional distribution of solutes in a material by determining the atomic coordinates and elemental identity of individual atoms. Recent advances in instrumentation, such as laser-assisted field evaporation, and FIB-based specimen preparation have significantly expanded the types and forms of materials that may be analyzed.
  
  
• In situ scanning transmission electron microscopy (STEM): a new system will be introduced for performing scanning transmission electron microscopy of specimens in liquid or gas environments at atmospheric pressure. The tutorial will include presentations of experimental data, description of theoretical models, and address aspects of sample preparation.
