Probing what happens to plutonium in a nuclear explosion

For years, research on nuclear weapons has relied on old data, limited experiments and computer modeling. But this year, that pattern has changed. Scientists have run new experiments that simulate what happens to plutonium ...

The art of hand-polishing precision optics

Growing up in a household of artists and engineers, Peter Thelin was destined for a career in which artistry mattered. Only for him, art has come in the form of manipulating the shapes, sizes and qualities of optics. And ...

Thinner capsules yield faster implosions

In National Ignition Facility (NIF) inertial confinement fusion (ICF) experiments, the fusion fuel implodes at a high speed in reaction to the rapid ablation, or blow-off, of the outer layers of the target capsule. To reach ...

Studying effects of target 'tents' on NIF

A systematic study of the effects on National Ignition Facility (NIF) implosions of the ultra-thin mounting membranes that support target capsules inside NIF hohlraums was reported by LLNL researchers in a Physics of Plasmas ...

Safe production in Industry 4.0

Production facilities and components of Industry 4.0 are linked to the Internet, networked with each other, and thus open to attack. Using an IT security laboratory, Fraunhofer researchers offer a test environment in order ...

X-rays unlock secrets of ancient scrolls buried by volcano

Scientists have succeeded in reading parts of an ancient scroll that was buried in a volcanic eruption almost 2,000 years ago, holding out the promise that the world's oldest surviving library may one day reveal all of its ...
