The Fundamental Parameter Space of Controlled Thermonuclear Fusion

Exploring the Range of Options

Few people are aware of the many conditions under which fusion can occur. Luckily, Irv Lindemuth and Richard Siemon have written a review of fusion to help the rest of us identify the density-temperature space where fusion gain can be achieved. The analysis offers a general understanding why there is such an extreme difference between the conventional approaches to controlled fusion, MCF (which uses a giant “magnetic cage” and ICF (which uses hundreds of laser beams pointed at a small target). It also helps us see how much of the parameter space of fusion has yet to be explored.

This clarifying overview of fusion came to our attention at the Fusion Power Associates Meeting, where Dr. Lindemuth presented a talk, now available (PDF file): Fusion Parameter Space from First Principles

The Abstract

Lindemuth and Siemon shine a light on magnetized target fusion, but their framework can be leveraged for plotting and comparing other approaches as well. It’s a handy document and covers a lot of the basics of fusion.

MCF and ICF

A Bridge from this article

The article was written with the goal of bridging the gap from plasma specialists to a broader audience of physicists.

It’s still written for physicists. And is behind a paywall.

We’d like to take steps to get this framework even more comprehensible and available, such that a general audience can relate to it.
