Webinar: HFIR Instrument Improvements Provide New Capabilities for World-leading Research, February 12, 2020

Teams at the High Flux Isotope Reactor (HFIR), which restarted October 29, 2019, took advantage of an extended outage to complete facility improvements and significant upgrades to 10 of 12 neutron scattering instruments. Designed to provide new and important scientific capabilities, the HFIR instrument upgrades include more advanced beam delivery systems, enhanced sample environments, better optics, and improved data acquisition systems and detectors. Of the 10 instrument projects, five were considered major upgrades. A webinar will be held at 1 p.m. EST, Wednesday, February 12, 2020, to highlight the upgrades. Instrument teams will be available to answer questions about the new capabilities. Please register if you plan to participate so we can gauge the interest level in this type of user communication event.

2020-B General User Proposal Call Closes February 26, 2020

The next proposal call for SNS and HFIR will close at noon February 26, 2020. This call will be for experiments anticipated to run at HFIR between May-December 2020, and at SNS between July-December 2020.
Read more about how to submit a proposal >
Submit your proposal >
For the 2020-A General User Proposal Call, SNS received a total of 613 instrument beam time requests on 574 proposals (39 proposals requested multiple instruments). One hundred eighty-three proposals were awarded beam time at SNS, and 99 proposals were placed in alternate status with the potential to be approved if scheduling allows. The subscription rate for SNS is 363%.
Subscription rate percentage is based on the number of General User Program (GUP) days requested divided by the number of GUP days available.

Staff Updates at SNS and HFIR

We are pleased to announce several new staff at SNS and HFIR. Gergely Nagy (left) has joined the EQ-SANS instrument team. His research interests focus on understanding the structures involved in photosynthesis and their dynamics. Next, Alicia Manjón Sanz and Cheng Li have joined the diffraction group as instrument scientists for POWGEN and NOMAD, respectively. Alicia’s research interests are in synthesis and elucidation of the structure-property relationships in advanced functional materials. Cheng’s research interest is to understand the structure (both local and long range) property relationship of functional materials using neutron diffraction. Janell Thomson (right), former Proposal Coordinator, accepted the position as the User Program Group Leader.

22nd National School on Neutron and X-Ray Scattering

The 22nd National School on Neutron and X-Ray Scattering will occur June 13-27, 2020. The main purpose of the school is to educate graduate students on the utilization of major neutron and x-ray facilities. Lectures, presented by researchers from academia, industry, and national laboratories, will include basic tutorials on the principles of scattering theory and the characteristics of the sources, as well as seminars on the application of scattering methods to a variety of scientific subjects. Students will conduct short experiments at Argonne's Advanced Photon Source and Oak Ridge's Spallation Neutron Source and High Flux Isotope Reactor facilities to obtain hands-on experience for using neutron and synchrotron sources.

The deadline for applications is February 17, 2020. Submit an application >

SNS-HFIR User Group (SHUG) Executive Committee (EC) Election Results

Martin Mourigal assumed responsibilities as the SHUG chair January 1, 2020. Danielle Yahne, Geneva Laurita, Daniel Shoemaker and Adrian Brügger were elected as new members. Daniel will serve as vice-chair and assume responsibilities as chair in 2021. They will join returning members Olivier Delaire, William Ratcliff, Dvora Perahia, Jarek Majewski, Eugene Mamontov, Allyson Fry-Petit, and Adam Aczel. The SHUG EC provides a direct interface between the users of the ORNL neutron scattering facilities and management. For more information about SHUG please go to the SHUG website, and read the letter from Martin Mourigal to the user community here.

New Chestnut Ridge Visitors Center opens at the Spallation Neutron Source

Users and visitors of the Spallation Neutron Source (SNS), High Flux Isotope Reactor (HFIR) and Center for Nanophase Materials Sciences (CNMS) can pick up badges and dosimeters at the Chestnut Ridge Visitors Center. The Chestnut Ridge Visitors Center is located at the SNS Office Building 8600, Room J-205 on the 2nd floor next to the User Office and lounge. The Chestnut Ridge Visitors Center will be open from 7:30 a.m. – 4 p.m., Monday through Friday.

ORNL workshop helps shape STS neutron science

Leading neutron science researchers attended the 2-day “Science at the Second Target Station” workshop, December 9-10, at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL). The event was held at ORNL’s Spallation Neutron Source (SNS) to encourage scientists to contribute ideas that would help lead to research capabilities and the initial suite of instruments at SNS’s future Second Target Station (STS). Attending onsite or remotely were nearly 300 members of the global neutron scattering community. The workshop featured plenary presentations, a poster session on STS concepts, and multiple breakout sessions covering a broad range of research areas and needs that the STS could help address. Read More  >

Send us your publications!

Your publications help us show our scientific productivity and the value of experiments completed using the SNS and HFIR instruments. Please send us any of your publications resulting from your work at SNS or HFIR. You can see if we already have your paper on our publication lists website.
Submitting your publication is now as simple as entering the DOI. We also want to hear from you if you have a recently completed dissertation that benefited from time at our facilities.

Connect your ORCiD

The ORNL Neutron Sciences user program began using ORCiD as a persistent identifier in October 2015. Obtaining an ORCiD is free and provides your name with a unique identifier.
You can easily add your ORCiD when registering at the ORNL Guest Portal, where users register to submit a proposal for beam time or request facility access when coming on site. If you haven’t yet added your ORCiD, please update your user profile in the ORNL Guest Portal.

Having user ORCiDs enables the User Program to develop a database of users and their unique identifiers, with the ability to push beam time award notices to a user’s ORCiD profile.

DOE internship and fellowship programs

The Department of Energy provides opportunities for students, postgraduates, senior scientists and faculty researchers to participate in research projects that offer insight into the federal government's role in the creation and implementation of policies that affect energy technology development.
Information about these opportunities and more may be found at the Oak Ridge Institute for Science and Education website.
