For the past few years, researchers at the Department of Energy’s SLAC National Accelerator Laboratory have been developing “virtual diagnostics” that use machine learning to obtain crucial information about electron beam quality in an efficient, non-invasive way. Now, a new virtual diagnostic approach incorporates additional information about the beam that allows the method to work in situations where conventional diagnostics have failed.
A team led by scientists at the Department of Energy’s SLAC National Accelerator Laboratory has invented a new type of accelerator structure that could make accelerators used for a given application 10 times shorter.
Scientists developed a new technique that uses intense X-ray pulses to measure how atoms move in a sheet of material one molecule thick. Scientists showed that movement of the atoms in a tungsten-selenium “blanket” layer caused the layer to stretch but not wrinkle. The research can help produce materials with new optical and electronic properties.
