Big data at the atomic scale: new detector reaches new frontier in speed

February 21, 2019

Staff scientists at Berkeley LabA team at the Department of Energy’s Lawrence Berkeley National Laboratory has designed a new kind of nano scale electron detector that captures all of the information in these interactions. This new tool, a superfast detector was installed on Feb. 12 at Berkeley Lab’s Molecular Foundry, a nanoscale science user facility where College of Chemistry faculty regularly carry out experiments. The new device will capture more images at a faster rate, revealing atomic-scale details across much larger areas than was possible before.
