Fusion News: Nature- Laser Fusion Experiment Extracts Net Energy From Fuel: Nature New & Comment
The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in California have, for the first time, extracted more energy from controlled nuclear fusion than was absorbed by the fuel to trigger it. This latest feat was published online, in Fuel gain exceeding unity in an inertially confined fusion implosion, in Nature and has gained a lot of media attention and expectations for the advancement of fusion. Even though there is still a long way to go for fusion this is a critical step. As reported by Nature in the article “Laser fusion experiment extracts net energy from fuel:” Philip Ball, Nature
The NIF team’s success, which is described in a paper published online today in Nature1, has come in experiments conducted between last September and this January. It relies on shaping the laser pulses to deliver more power early in the pulse. This creates a relatively high initial temperature in the hohlraum that ‘fluffs up’ the plastic shell and makes it less prone to an instability during the explosion that disrupts the fusion process. “This fluffing up greatly slows down growth of the instability,” says team leader Omar Hurricane, a Livermore physicist.
