The Center for X-Ray Optics is a multi-disciplined research group within Lawrence Berkeley National Laboratory's (LBNL) Materials Sciences Division (MSD). Notice to users.
"Many exciting areas of research require observing the dynamics of nanoscale systems. Researchers from around the world use XM-1's unique combination of 10-nm spatial resolution and 70-ps temporal resolution to study nanoscale properties that are challenging or impossible to see in other ways."
Mi Young Im,
XM-1 combines: spatial resolution approaching 10 nm, elemental specificity, 70 ps temporal resolution (set by the bunch length of the x-ray pulses), and high sensitivity to spin configurations (via dichroism effects with polarized x-rays) making it a unique analytical tool for nanoscience research. Every day, scientists working in areas such as spintronics, nanoscale materials science, x-ray optics and environmental sciences come to XM-1 to unlock nanoscale properties that are challenging or impossible to see in other ways.
