Congressman Eric Swalwell visited the Laboratory Monday to witness an experiment at the National Ignition Facility (NIF). After an initial overview by NIF Director Mark Herrmann, Swalwell was greeted by Lab Director Bill Goldstein, Livermore Field Office Manager Nicole Nelson-Jean and NIF &...

Researchers toss around rugby-shaped hohlraums for ignition experiments

May. 1, 2015 -  
For several years, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) has pursued an indirect drive approach to ignition, using cylindrically shaped gold cans known as hohlraums. In this configuration, all of NIF’s 192 laser beams enter the hohlraum through a pair...

Promising new X-ray microscope poses technical challenges

Apr. 30, 2015 -  
You may think the aisles in your neighborhood convenience store are crowded, but they’d look positively spacious compared to the passageways in the NIF target bay. The target bay bristles with dozens of instruments needed for NIF experiments, ranging from inserters that hold NIF targets in place to...
