To get more fusion energy out than you put in, a plasma must be hot enough, dense enough, and confined long enough — captured together in the triple product n·τ·T. The Lawson criterion sets the threshold for ignition, where the fusion self-heats. Crossing it, at over 100 million degrees, is the decades-long goal of tokamaks and laser fusion.

About this simulation
The full Fusion (Lawson) tool models a nuclear decay with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions
- How do I simulate a nuclear decay?
- Open this page and use the live Fusion (Lawson) tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
- Is it free?
- Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
- Can I use my own numbers?
- Absolutely — every input is adjustable, and with data import you can drive a nuclear decay from your own measurements.
