The softer side of NIF hohlraums

Mar. 17, 2017 -  
Considering that nothing precious comes from an online retailer without protective padding, could precision laser targets also benefit from similar high-tech swaddling? So far the answer is yes, for a group of scientists developing new target technologies for NIF that are intended to neutralize...

National Ignition Facility's dual-purpose positioner is proving its worth

Feb. 16, 2017 -  
While multitasking may be easy for some people (and perhaps hard for others), it can be a particular challenge for the highly specialized equipment used to carry out experiments on the National Ignition Facility (NIF). But TanDM, NIF's new Target and Diagnostic Manipulator, is designed to do just...

National Ignition Facility tops 400 shots in FY16

Sep. 26, 2016 -  
LIVERMORE, California - On Sept. 18, the National Ignition Facility (NIF) performed its 400th experiment of fiscal year (FY) 2016, meeting the year's goal several weeks early. In comparison, the facility completed 356 experiments in FY15 and 191 experiments in FY14. NIF is on track to complete 415...

Diagnostic provides top-down view of neutrons

Jun. 13, 2016 -  
A new diagnostic built on the National Ignition Facility's (NIF) roof is giving researchers a clearer picture of the neutrons released during laser-driven implosions of target capsules containing deuterium or deuterium and tritium (DT). Instruments inside the North Pole neutron Time of Flight (nTOF...

NIF experiments shed light on turbulent mix

Feb. 2, 2016 -  
Scientists from Los Alamos National Laboratory (LANL) are leading an experimental campaign on the National Ignition Facility (NIF) designed to further understand turbulent mix models used in both high energy density (HED) and inertial confinement fusion (ICF) experiments. NIF is the only facility...

Shaped laser pulse experiments boost understanding of NIF performance

Oct. 15, 2015 -  
In a recent series of papers, Lawrence Livermore National Laboratory (LLNL) scientists examined the role of ablation-front instability and capsule convergence ratio in ignition science experiments at the National Ignition Facility (NIF). The papers address different aspects of an "adiabat-shaping"...

Researchers put pressure on hydrogen

Sep. 23, 2015 -  
A National Ignition Facility (NIF) experimental campaign may have unlocked scientific secrets behind how hydrogen becomes metallic at high pressure. "Hydrogen properties are still puzzling," said Lawrence Livermore National Laboratory (LLNL) physicist Marius Millot. "In particular, back in 1935, it...

Experiments illuminate supersonic radiation flow

Sep. 9, 2015 -  
A multi-institutional team of scientists fired the 26th and final shot of the Pleiades experimental campaign at the National Ignition Facility last month. The campaign has created a new scientific foundation for the study of supersonic radiation flow in astrophysical phenomena and in inertial...

National Ignition Facility fires 300th shot in FY15

Aug. 18, 2015 -  
Last week, the National Ignition Facility (NIF) fired its 300th laser target shot in fiscal year (FY) 2015, meeting the year's goal more than six weeks early. In comparison, the facility completed 191 target shots in FY 2014. Located at Lawrence Livermore National Laboratory (LLNL), the NIF is the...
