National Ignition Facility Takes First Steps Towards Fusion Energy

sciencehabit writes "As it approaches its fifth birthday, the National Ignition Facility (NIF), a troubled laser fusion facility in California, has finally produced some results that fusion scientists can get enthusiastic about. In a series of experiments late last year (abstract 1, abstract 2), NIF researchers managed to produce energy yields 10 times greater than produced before and to demonstrate the phenomenon of self-heating that will be crucial if fusion is to reach its ultimate goal of 'ignition'—a self-sustaining burning reaction that produces more energy than it consumes."

Now that the Voodoo is swept away

I love this bit from TFA:

In 2013, NIF researchers began to explore the problems more scientifically; there was also a change of leadership at the lab and new researchers joined the team.

Apparently casting those chicken bones under the reactor had no effect and they had to switch to SCIENCE!

Sigh. Journalism majors.

The issue is that the previous management were attempting to achieve ignition through an engineering approach. They assumed that the science was well understood and all they needed to do was tweak the knobs and dials on the laser until they got the result they wanted.

When this spectacularly failed to work there was a change in leadership and the new guys are actually doing experiments rather than just firing the 'ignition' capsule over and over.
