Abstract Scope |
The Second Target Station (STS) at the Spallation Neutron Source (SNS) will provide a world-leading capability in high-brightness cold neutron beams with broad energy/wavelength ranges to meet challenges at the frontiers of matter and energy. Two next-generation neutron diffractometers - PIONEER and VERDI - are currently under design using advanced optics to leverage the STS source characteristics. These instruments will offer new science opportunities in materials science and technology that can lead to breakthrough discoveries. PIONEER is a high Q-resolution, single-crystal neutron diffractometer capable of significantly lowering the sample size barrier for neutron diffraction. VERDI is a wide-wavelength bandwidth diffractometer with full polarization analysis capabilities for complex magnetic structure studies in powders and single crystals. Both instruments will support various sample environments, including low and high temperatures, magnetic fields, and pressure. We will present the instrument development status and introduce their transformative capabilities using virtual experiment examples. |
