Dynamic compression provides new insight into understanding and predicting crystal growth

June 4, 2019 -  
Crystal growth is a crucial issue for fundamental science and wide applications. The growth morphology and speed are generally determined by an interplay between macroscopic thermodynamic driving forces and the microscopic kinetic process at crystal-liquid interface. While crystal growth is well...

Making metal with the lightness of air

June 3, 2019 -  
Gold, silver and copper are heavy metals, but LLNL scientists can now make them nearly as light as air — in a form so tiny it can ride on a mosquito’s back. The groundbreaking science, part of a joint NIF/Physical and Life Sciences (PLS) project supported by the Laboratory Directed Research and...

ARC experiments exceed expectations

May 17, 2019 -  
The first proton-acceleration experiments using the National Ignition Facility ’s (NIF) Advanced Radiographic Capability ( ARC ) short-pulse laser have produced protons with energies about 10 times higher than previous experience would have predicted (see “ A Powerful New Source of High-Energy...

Giant lasers crystallize water with shockwaves, revealing the atomic structure of superionic ice

May 8, 2019 -  
Scientists from Lawrence Livermore National Laboratory ( LLNL ) used giant lasers to flash-freeze water into its exotic superionic phase and record X-ray diffraction patterns to identify its atomic structure for the very first time — all in just a few billionths of a second. The findings are...

Sandia’s Line VISAR has roots in Livermore

April 10, 2019 -  
A joint Lawrence Livermore National Laboratory ( LLNL )/ Sandia National Laboratories team has commissioned a Line Velocity Interferometer System for Any Reflector (Line VISAR) at Sandia’s Z Machine. Line VISAR is used to measure the velocities of shocks and surface motions when enormous pressures...

LLNL’s Virtual Beam Line++ now available

April 5, 2019 -  
Physicists designing new laser systems and modeling laser performance at Lawrence Livermore National Laboratory ( LLNL ) now have a powerful new tool in their hands with the Rigel release of Virtual Beam Line++ (VBL++). The current version of VBL, a java-based code, has been in use since 2000. VBL...

New method for better laser-material interaction

April 3, 2019 -  
Using ultrashort laser pulses lasting a few picoseconds (trillionths of a second), Lawrence Livermore National Laboratory ( LLNL ) researchers have discovered an efficient mechanism for laser ablation (material removal) that could help pave the way to the use of lower-energy, less costly lasers in...
