--- Quote ---A new technique to monitor a process called 'fast ignition' has been developed, in what could be a critical step towards a viable method of creating controlled nuclear fusion. Fusion ignition, the point at which a nuclear reaction becomes self-sustaining, is one of the great hopes for a new generation of clean, cheap energy generation. But while the reactions have been seen in the cores of thermonuclear weapons, it has yet to be achieved in a controlled manner in a reactor. One of the possibilities for developing the tech for real is known as the fast ignition process. This two-stage laser process first uses hundred of lasers to compress the fusion fuel -- a mixture of deuterium and tritium in a spherical plastic capsule -- and then uses a high-intensity laser to rapidly heat the compressed fuel.

It's by far the lowest-energy method of potentially creating nuclear fusion, but in order for it succeed, energy from the high-intensity laser must be directed straight at the densest region of the compressed fuel. Previously it wasn't known how to do this, but now a research team led by scientists and engineers at the University of California, San Diego and General Atomics has found a way.
