Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons with powerful X-ray laser bursts just 280 attoseconds, or billionths of a billionth of a second, long. The technology, called X-ray laser-enhanced attosecond pulse generation (XLEAP), is a big advance that scientists have been working toward for years, and it paves the way for breakthrough studies of how electrons speeding around molecules initiate crucial processes in biology, chemistry, materials science and more.
Phil Bucksbaum has been awarded the 2020 Norman F. Ramsey Prize in Atomic, Molecular and Optical Physics, and in Precision Tests of Fundamental Laws and Symmetries. The prize recognizes outstanding accomplishments in the two fields in which Norman Ramsey excelled: (1) Atomic, Molecular and Optical Physics, and (2) Precision Tests of Fundamental Laws & Symmetries. The award is “For pioneering explorations of ultrafast strong field physics from the optical to the X-ray regime.” Norman F. Ramsey Prize
Experiments at SLAC’s X-ray laser reveal in atomic detail how two distinct liquid phases in these materials enable fast switching between glassy and crystalline states that represent 0s and 1s in memory devices.
