NSLS-II Welcomes New Tool for Studying the Physics of Materials

Versatile instrument for precisely studying materials’ structural, electronic, magnetic characteristics arrives at Brookhaven Lab.

A new instrument for studying the physics of materials using high intensity x-ray beams has arrived at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory. This new diffractometer, installed at beamline 4-ID at the National Synchrotron Light Source II (NSLS-II), a DOE Office of Science User Facility that produces extremely bright beams of x-rays, will offer researchers greater precision when studying materials with unique structural, electronic, and magnetic characteristics. Understanding these materials’ properties could lead to better electronics, solar cells, or superconductors (materials that carry electricity with almost no energy loss).

A diffractometer allows researchers to “see” the structure of a material by shooting highly focused x-rays at it and measuring how they diffract, or bounce off. According to Brookhaven physicist Christie Nelson, who worked with Huber X-Ray Diffraction Equipment to design the diffractometer, the new instrument has big advantages compared to one that operated at Brookhaven’s original light source, NSLS. Most significantly, it gives researchers additional ways to control where the beam hits the sample and how the x-rays are detected.
