In October, SLAC installed the first of LCLS-II’s cryogenic “feed caps” and “end caps.”
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.
With SLAC’s X-ray laser, a research team captured ultrafast changes in fluorescent proteins between “dark” and “light” states. The insights allowed the scientists to design improved markers for biological imaging.
SLAC’s X-ray laser and Matter in Extreme Conditions instrument allow researchers to examine the exotic precipitation in real time as it materializes in the laboratory.
Following the 2017 American Physical Society (APS) general election, Philip Bucksbaum will be vice president of APS in 2018 – an election that places him in the presidential line. He will become president-elect in 2019 and president in 2020.
SLAC’s ultrafast “electron camera” reveals unusual atomic motions that could be crucial for the efficiency of next-generation perovskite solar cells.
The research team was able to watch energy from light flow through atomic ripples in a molecule. Such insights may provide new ways to develop a class of materials that improve efficiency and reduce the size of applications like solar cells and memory storage devices.
Extraordinarily precise measurements -- within millionths of a billionth of a second and a billionth of a hair's breadth -- show this ‘electron-phonon coupling’ can be far stronger than predicted, and could potentially play a role in unconventional superconductivity.
A new X-ray laser technique allows scientists to home in on these single-electron triggers to better understand organic molecules that respond to light, including receptors in your eyes, plastic products and DNA building blocks that need to protect themselves from cancer-causing mutations.
The method dramatically reduces the amount of virus material required and allows scientists to get results several times faster.
