Nearly 200 lasers fired at a tiny bit of fuel to create a gain in energy, mimicking the power of the stars.
The National Ignition Facility's target chamber at Lawrence Livermore National Laboratory, where fusion experiments take place, with technicians inside.Since the 1950s, scientists have quested to bring nuclear fusion—the sort of reaction that powers the sun—down to Earth.
On the outside, NIF is a nondescript industrial building in a semi-arid valley east of San Francisco. On the inside, scientists have quite literally been tinkering with the energy of the stars . Then, scientists fire a laser—which splits into 192 finely tuned beams—which, in turn, enter the hohlraum from both ends and strike its inside wall.“We don’t just smack the target with all of the laser energy all at once,” says, a scientist at NIF, at the press conference. “We divide very specific powers at very specific times to achieve the desired conditions.”
