120 Physics Building
Dr. Ken Herwig, Oak Ridge National Laboratory, will present, "Prospects for a Second Target Station at the Oak Ridge National Laboratory Spallation Neutron Source," Monday, Dec. 5 at 4:00 pm, 120 Physics Building.
Oak Ridge National Laboratory is home to two Department of Energy neutron facilities that comprise a world-leading center for neutron sciences, providing researchers with cutting-edge neutron scattering capabilities. The Spallation Neutron Source (SNS) first target station and the High Flux Isotope Reactor (HFIR) currently support 30 neutron scattering instruments available in the general user program. I will briefly review plans to complete the instrument suite at SNS by building out the five remaining empty beam lines and present the possibilities for a re-optimized cold neutron guide hall at HFIR. However, most of this talk will focus on the exciting prospect of constructing a Second Target Station (STS) at the SNS producing the world’s highest peak brightness beams of cold neutrons. I will discuss the science context that led to the design characteristics of STS and its complementarity to current neutron sources, give an overview of the target and moderator technology that produce high brightness beams and describe the suite of neutron scattering instruments that form the basis for concept development. I will conclude with a look ahead at a few science examples illustrating the power of STS and an update of near term activities.
