Neutron production at ORNL’s SNS reaches design power level

SNS has broken a new record by ending its first neutron production cycle in FY 2019 at its design power level of 1.4 MW. Higher power provides more neutrons for researchers who use the facility to study a wide range of materials. The achievement marks a new operational milestone for neutron scattering in the United States and opens the door to studying significantly smaller materials with greater complexity. Read More >

SNS-HFIR proposal call awards

Award notifications for the 2019 proposal call were sent out on November 12, 2018. A total of 859 instrument requests were submitted and 389 were awarded beam time.

The 2019-B Proposal Call is now open and will close March 27, 2019.​ Read More >

SNS-HFIR User Group (SHUG) Executive Committee election results

Four new members were elected to the SNS-HFIR User Group Executive Committee (SHUG EC). Their terms will start in January 2019 and run through December 2021.
Olivier Delaire: Olivier is an associate professor at Duke University in the Department of Mechanical Engineering and Materials Science and the Department of Physics. His research makes extensive use of large computer simulations to model neutron data, fostering connections between neutron scatterers, theorists and computer scientists, within ORNL and beyond.

Jarek Majewski: Jarek is currently a program director at the Molecular Biophysics Cluster in the Division of Molecular and Cellular Biology at the National Science Foundation. He is on a leave of absence from Los Alamos National Laboratory where, over the past 20 years, he has built a successful x-ray and neutron scattering program to address interfacial structures and properties of materials.

Martin Mourigal: Martin is an assistant professor of physics at the Georgia Institute of Technology. His scientific expertise is in the magnetic dynamics of quantum antiferromagnets and spin-liquids. In his laboratory at Georgia Tech, students and postdocs engage in a broad portfolio of quantum materials techniques, including sample synthesis and characterization, inelastic neutron scattering, and theoretical modelling.

William Ratcliff: William is a physicist at the NIST Center for Neutron Research, where he is responsible for a triple-axis-spectrometer. His research is in the area of hard condensed matter physics. In particular, he has a long-standing interest in multiferroic materials, as well as a recent interest in topological materials.

Many thanks to SHUG EC members Antonio Faraone, Sara Haravifard, Kate Ross, and Gerald Schneider, who are completing their 3-year terms of service this December.

The SHUG EC provides a direct interface between the users of the ORNL neutron scattering facilities and facility managers. For more information about SHUG, please go to the SHUG website.

Neutron pinhole magnifies discoveries at Oak Ridge National Laboratory

A team of engineers and scientists from ORNL have developed a new pinhole-based diffraction technique they call PIND. In a paper published in Applied Physics Letters, they proved that it was possible to drastically improve the magnification and resolution of structures deep within engineered components with pinhole diffraction. “Moving forward, we are putting plans in place to replace all of VULCAN’s detectors with the new and improved detectors and to complete more research to see how much we can further improve the resolution on neutron diffractometers with the PIND technique,” said Ke An, ORNL instrument scientist.

GRC on Neutron Scattering, Hong Kong, May 5–10, 2019

The Gordon Research Conference (GRC) on Neutron Scattering will be held May 5–10, 2019, at the Courtyard by Marriott in Hong Kong Sha Tin. The GRC meeting of 2019 will focus on “Emerging Neutronic Approaches for Advanced Materials Study and Innovation in Energy, the Environment, Health and Infrastructure.” Along with the GRC, there will be a Gordon Research Seminar on Neutron Scattering entitled “Synergy of Neutron Scattering and Complementary Tools to Reveal New States of Matter,” which is being organized by and for graduate students and postdocs in the area of neutron scattering. It will be held on May 4–5, 2019, just before the GRC. Read More >

Shull Wollan Center afternoon coffee breaks

Need an afternoon coffee break? Stop by the break room in the Shull Wollan Center on Tuesdays and Thursdays from 3:30 to 4:00 p.m. to grab a cup and talk with fellow users and staff. The Shull Wollan Center is located at the SNS complex in Building 8630, between the ORNL Guest House and main SNS office building (Building 8600).

ORCiD Update: Reviewer Committee Service

ORNL’s Neutron Sciences User Office continues to publish SNS and HFIR beam time awards as researcher ORCiD records under “Funding." Development is under way to begin publishing SNS/HFIR Science Review Committee service to ORCiD records under “Service.” This record would not identify specific committees, roles, or review dates, but is simply a record of service to ORNL. These features are opt-in and are available to all researchers who provide their ORCiDs to ORNL and grant permission to update ORCiD with information related to research performed at ORNL. To connect your ORCiD profile to ORNL or to manage the existing connection and permissions, log into the ORNL Guest Portal at

American Museum of Science and Energy (AMSE) now open at new location

AMSE held its grand opening on October 18 to welcome visitors to its new location in Oak Ridge. The new 18,000-square foot space includes a newly designed exhibit gallery featuring state-of-the-art interactive exhibits and hands-on activities, as well as a lecture hall and classroom facilities. AMSE will also partner with the National Park Service to host programs for the Manhattan Project National Historical Park.

The SNS-HFIR User Channel: Knowledge worth sharing

SNS-HFIR, in conjunction with the SHUG, has launched a new User channel on Vimeo. Think of it like SNS-HFIR–focused TED talks. The videos on this channel will update you on instrument capabilities, give you a place to share your user experience, and provide tutorials to help you learn how to get the most out of SNS-HFIR. Visit the SNS-HFIR User channel here.​
