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...

Tom Epperly: A software architect starts early

Feb. 13, 2019 -  
For Tom Epperly, writing software is both a lifelong avocation and a hobby. So, working on a major redesign of NIF ’s Virtual Beam Line (VBL) code is a dream come true. As the software architect of the VBL++ project, he is part of the team responsible for reimplementing the older Java-based VBL...

LLNL, universities form HED science alliance

Feb. 4, 2019 -  
High-energy density (HED) science is foundational to the nationally important research conducted by Lawrence Livermore National Laboratory ( LLNL ) — yet few universities offer programs geared for the study of matter and energy under extreme conditions. And even fewer offer such courses for...

Two-micron fill tubes fill two needs

Dec. 12, 2018 -  
Lawrence Livermore National Laboratory's National Ignition Facility ( NIF ) and General Atomics engineers have created an inertial confinement fusion (ICF) fuel capsule with a 2-micron-diameter fill tube — and along the way, found a solution to a “Bay Bridge”-like dilemma that could have...
