Measuring iron in motion at earth-core conditions

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from the Earth’s surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several universities used the National Ignition Facility (NIF) to recreate those extreme temperature and pressure conditions of the Earth’s inner core…

Researchers create first-of-a-kind laser spring with LLNL’s highest-precision optics to date

When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated a rotating, spring-shaped laser pulse, opening up new possibilities for fusion energy, particle acceleration, astrophysics and beyond. In new…

In an inertial confinement experiment on the National Ignition Facility, the lasers converge at tiny entrance holes at the top and bottom of the hohlraum. The intersection of the lasers enables crossed-beam energy transfer, an important factor in maintaining symmetry of implosions.

Research sheds new light on laser polarization effects in NIF experiments

Experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the top or bottom of a 2-centimeter gold canister known as a hohlraum. As they enter, the beams intersect in plasma and transfer power, a process known as…

LLNL experts help advance inertial fusion energy at U.S. IFE conference

Researchers from Lawrence Livermore National Laboratory (LLNL) joined their counterparts from national laboratories, universities, industry and government in a conference last month to discuss the progress, challenges and priorities for moving toward an inertial fusion energy (IFE) future in the United States. The U.S. IFE conference brought together the growing IFE…

Adding an optimized void structure (top right) counteracts a shockwave-induced instability, reducing jetting (bottom right) that can interfere with inertial confinement fusion. Without this void, significant jetting occurs (bottom left). (Image: Strucka et al.)

Looking into the void to cancel out material instabilities

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates fast, narrow jets of material — called the Richtmyer…

Big Ideas Lab podcast zooms in on tiny targets

At the end of an inertial confinement fusion (ICF) experiment at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the target, measuring just two centimeters, is mostly obliterated. The gold plating, the high-density carbon and months of meticulous assembly vanish in an instant. That’s the point. In that flash, the target becomes what NIF is built…
