Laser Driven Fusion Explained

Written by Tim Lash, Focus Fusion Society Contributor. FocusFusion.org has featured several laser based fusion stories. This is another, but from a slightly different angle. A couple summers ago Dr. Kate Lancaster gave a presentation to the Royal Institute in London. Her talk covers laser basics, high energy laser interactions with matter and laser driven fusion. Fortunately this talk was captured on video and preserved on Youtube. Dr. Lancaster studies the use of lasers for inertial confinement fusion. The lecture begins by covering laser basics. She explains how laser light is generated and its unique characteristics. One interesting fact she shared is that the average home has three lasers. This contrasts with the sentiment right after discovery; that the laser […]

Artificial Intelligence in Fusion Research

Written by Tim Lash, Focus Fusion Society Contributor. Prior FocusFusion.org posts covered the intersection between fusion research and artificial intelligence (AI). AI is likely to become more important to the advancement of fusion research. Recent reports highlight more projects bringing AI to bear on the challenge of viable fusion power generation. A December report provides insight into what researchers are calling a Fusion Recurrent Neural Network (FRNN). Scientists affiliated with Princeton Plasma Physics Laboratory (PPPL) are trying to craft a neural network that predicts failure of magnetic containment in tokamak fusion reactors. The common tokamak design in fusion research is prone to reactor damage if hot plasma escapes containment. Julian Kates-Harbeck is the lead architect for software that uses artificial […]

Plasma Rings

Written by Tim Lash, Focus Fusion Society Contributor. Here at FocusFusion.org we love aneutronic fusion. Aneutronic fusion is fusion without neutrons. The same type being pursued by LPPFusion. Another effort in pursuit of aneutronic fusion is TAE. Formerly known as Tri-Alpha Energy, TAE recently made news by securing time on a national super computer. TAE intends to achieve usable aneutronic with the help of computer modeling and guidance. TAE calls its approach to fusion “Friendly Fusion” power. Their device, called a field reversed configuration, or FRC, generates two large rings of plasma and heats them with an externally accelerated ion beam. These rings collide generating fusion reactions between hydrogen and boron fuel constituents. The fusion fuel is controlled without magnets […]

Laser Driven Fusion

Written by Tim Lash, Focus Fusion Society Contributor. LPPFusion has been working toward net energy gain from a hydrogen-boron fusion reactor. LPPFusion’s approach uses natural plasma instabilities to generate the high temperatures and densities necessary for fusion. They have already demonstrated world record ion temperatures in their device. New beryllium electrodes will allow them to tackle the needed densities. However, an Australian lead international team is approaching hydrogen-boron reactions driven by a completely different mechanism. Physicist Heinrich Hora plans to use picosecond laser pulses to initiate aneutronic fusion. Two prior Focus Fusion Society posts have discussed laser driven fusion. This Australian team seems to be inspired by the promising outlook from this earlier research. In fact, the Australian team has […]
