Second Target Station Instrument Selection

The STS Project plans to build 8 initial instruments ready to transition to operations and begin commissioning by the end of the project. The STS Project is actively seeking participation from the research community in the process leading to final selection of these 8 instruments.

The Second Target Station (STS) at Oak Ridge National Laboratory’s (ORNL) Spallation Neutron Source (SNS) will provide transformative new capabilities for discovery science enabling breakthroughs in many areas of materials research and development. As discussed in the First Experiments: New Science Opportunities at the Spallation Neutron Source Second Target Station report, STS will provide unique capabilities for experiments that require:

  • Time-resolved measurements of kinetic processes and beyond-equilibrium matter
  • Simultaneous measurements of hierarchical architectures from the atomic scale to microns and beyond
  • Measuring small samples of newly discovered or synthesized materials
  • Examining new frontiers in materials at extreme conditions.

The STS will have capacity for 22 beamlines that will complement beamlines at the SNS First Target Station and High Flux Isotope Reactor. The STS Conceptual Design Report Volume 1: Overview, Technical and Experiment Systems contains details on anticipated performance and descriptions of some initial instrument concepts.

Science opportunities enabled at the STS have been discussed at previous workshops and in the First Experiments report that map on to an initial set of instrument concepts. An ORNL point-of-contact (POC) has been identified for each of the instrument concepts on this initial list. Researchers desiring to be part of a proposal team and participate in developing the science case and instrument requirements for these instruments should contact the relevant POC. The STS Project also invites the research community to submit new ideas for instruments beyond the initial list, beginning with notification of Ken Herwig, the STS Instrument Systems Manager.

Evaluation of all instrument concepts will follow the process described in the Selection Process for Second Target Station Project Instruments that includes guidance on proposal team formation, proposal development, the selection requirements and reviews. The process requires submission of both preliminary and full instrument proposals. Proposal teams should use the STS Project Preliminary Instrument Proposal Template when preparing proposals.
