The National Ignition Facility (NIF) at Livermore National Lab is the culmination of a 50+ year program of developing "laser fusion." However, as was clarified for readers of the NY Times in 2012, NIF was "conceived, designed, built and funded" to support the nuclear weapons program, not to develop fusion energy (https://drive.google.com/file/d/0B5czjPh_Pq6hc0tBai0yejF5MEk/view?usp=sharing). On the other hand, Livermore doesn't mind the boost in taxpayer support from people mistakenly assuming fusion energy is part of their mission AND/OR that lasers are the best technology for "driving" these fusion fuel pellets --- possibly resulting in a "spin-off technology" for fusion energy.
In fact, particle accelerators are vastly superior to lasers for practical "inertial fusion" power plants. This observation has been made again and again by physicists who are expert in these matters, and recorded in publicly available reviews of the U.S. fusion energy program down through the decades. Nobody reads these dry technical reports but the answer is in there, "hidden in plain sight," if you look carefully. Here's some excerpts:
1. The 1979 Foster Committee produced a classified report which is hidden some place in the bowels of the DOE. However, Johnny Foster reported to the Energy Research Advisory Board at its May 3, 1979, meeting saying, “...heavy ion accelerators have great promise as reactor candidates because of their inherently high efficiency, developed repetitive-pulse technology, and favorable theoretical predictions of target coupling.”
2. The Jason Report of January 1983 (JSR82-302) stated, “We conclude that the uncertainties in coupling physics for high-energy heavy ions are minimal.”
3. The National Academies of Sciences Report of March 1986 entitled, “Review of the Department of Energy’s Inertial Confinement Fusion Program” stated “Heavy ion beams may well be the best eventual driver for energy applications.”
4. The 1990 report of the Fusion Policy Advisory Committee (Stever Panel) recommended parallel development of inertial and magnetic fusion with a budget level of about $30 million per year for HIF.
5. The 1993 Fusion Energy Advisory Committee (Davidson Panel) said, “We recognize the great opportunity for fusion development afforded the DOE by a modest heavy-ion driver program that leverages off the extensive target program being conducted by the Defense Department... .”
6. The 1996 FESAC (Sheffield) report said, “In agreement with previous reviews, we consider the heavy ion accelerator to be the most promising driver for energy applications.”
