In a major step forward, SLAC’s X-ray laser captures all four stable states of the process that produces the oxygen we breathe, as well as fleeting steps in between. The work opens doors to understanding the past and creating a greener future.
Tais Gorkhover, Michael Kagan, Kazuhiro Terao and Joshua Turner will each receive $2.5 million for research that studies fundamental particles, nanoscale objects, quantum materials and machine learning.
With X-ray imaging at SLAC’s synchrotron, scientists uncovered a 6th century translation of a book by the Greek-Roman doctor Galen. The words had been scraped off the parchment manuscript and written over with hymns in the 11th century.
In experiments with the lab’s ultrafast "electron camera," laser light hitting a material is almost completely converted into nuclear vibrations, which are key to switching a material’s properties on and off for future electronics and other applications.
This novel method could shrink the equipment needed to make laser pulses billionths of a billionth of a second long for studying ultra-speedy electron movements in solids, chemical reactions and future electronics.
