Extremely small and fast: Laser ignites hot plasma

When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma is created. The electrons ...

Jet-propelled imaging for an ultrafast light source

John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging. It's a particularly ...

Alternative material for superconducting radio-frequency cavity

In modern synchrotron sources and free-electron lasers, superconducting radio-frequency cavity resonators are able to supply electron bunches with extremely high energy. These resonators are currently constructed of pure ...

Under pressure: Solid matter takes on new behavior

Investigating how solid matter behaves at enormous pressures, such as those found in the deep interiors of giant planets, is a great experimental challenge. To help address that challenge, Lawrence Livermore National Laboratory ...

Terahertz waves from electrons oscillating in liquid water

Ionization of water molecules by light generates free electrons in liquid water. After generation, the so-called solvated electron is formed, a localized electron surrounded by a shell of water molecules. In the ultrafast ...

Free-electron lasers reveal detailed architecture of proteins

(Phys.org) -- In the centennial year of Max von Laue’s discovery that X-ray diffraction can be used to unravel the atomic architecture of molecules, a new approach to the determination of high-resolution structures has ...
