Fast ignition is an alternate concept in inertial confinement fusion, which has the potential for easier ignition and greater energy multiplication. If realized, it could improve the prospects for inertial fusion energy. It poses stimulating challenges in science and technology, and the research is approaching a key stage in which the feasibility of fast ignition will be determined. This review covers the concepts, the state of the science and technology, the near-term prospects, and the challenges and risks involved in demonstrating high-gain fast ignition.
