Study reveals cause of 3D asymmetry in ICF implosions

Feb. 25, 2021- 
Inertial confinement fusion (ICF) implosions require very high levels of symmetry in order to reach the high densities and temperatures required for fusion induced self-heating. Even percent-level deviations from perfect spherical symmetry can lead to significant distortions of the implosion and ultimately degrade fusion performance. To that end, researchers from Lawrence Livermore...

Magnetic fields drive astrophysical jet shapes

Feb. 23, 2021- 
Outflows of matter are general features stemming from systems powered by compact objects such as black holes, active galactic nuclei, pulsar wind nebulae, accreting objects such as Young Stellar Objects (YSO) and mature stars such as our sun. But the shape of those outflows, or astrophysical jets, vary depending on the magnetic field around them. In new experiments, a Lawrence...

LLNL scientists discover a new way that metals freeze at extreme conditions

Feb. 22, 2021- 
Since the dawn of civilization, metallurgy has determined the fate of powerful cities, states and empires. Blacksmiths have harnessed the power of heat to melt simple metals that would then be cast into hard, sharp and shiny alloys. Varying process conditions, such as rate of cooling and composition, can lead to new materials with dramatically different mechanical properties, such as...

LLNL weapon engineers, biologists deliver critical samples to identify skin proteins left on IEDs

Feb. 17, 2021- 
Following a terrorist bombing, can the bomb maker be identified by skin proteins left on the bomb components they handled? To address this question, Lawrence Livermore National Laboratory (LLNL) personnel from Weapons Complex Integration (WCI) and Global Security (GS) Forensic Science and Biosecurity Centers (FSC/BSC) subjected notional bomb components handled by LLNL volunteers to...

Research on transition phenomena to aid in improving safety of explosives

Feb. 16, 2021- 
On Aug. 4, 2020, a massive explosion rocked Lebanon’s capital of Beirut, sending shockwaves through the city and shattering windows, reducing some buildings to rubble and killing at least 200 people. Officials have since traced the blast to a stockpile of more than 2,500 tons of confiscated ammonium nitrate stored in a port warehouse. While the official investigation is ongoing, it...

What Hollywood gets wrong, and right, about asteroids

Feb. 11, 2021- 
Meet Kirsten Howley, the real-life astrophysicist working to prevent an asteroid “Armageddon” In the 1998 movie “Armageddon,” an asteroid the width of Texas is about to hit Earth. The heroes who stop it in the nick of time are a group of orange-suited Americans, all men. Life isn’t always like the movies. Not that an asteroid couldn’t slam into Earth, mind you...
