BETA PHASE!(NEED FEEDBACK!)

Fusion Circus is a nuclear fusion tokamak simulator I built to teach myself plasma physics. It started with a video game. Here’s the story
Growing up, I was fascinated with Megaman and his Mega Buster — a weapon that creates pure energy. All of Dr. Light’s work revolved around energy creation. Robots powered by limitless clean energy. A future where power wasn’t a problem. As a kid, I thought it was just sci-fi. Then I got older and discovered AI and neural networks. The idea that machines could learn, adapt, optimize. But where’s the energy creation part? That sparked something. Energy creation + intelligent systems? What if that wasn’t fantasy? What if someone was actually building Dr. Light’s dream? Yupp they’re real ITER in France. JET in the UK. KSTAR in South Korea. Dozens of facilities worldwide are chasing nuclear fusion. The same energy that powers the sun. 150 million degrees. Plasma hotter than stars. Contained by magnetic fields. This is real. Right now. I had to understand it. My background is industrial equipment. I worked as a heavy machinery field service technician. I know machines. I know systems. I know what it takes to keep complex equipment running. But plasma physics? That was a new domain. So I built myself a virtual playground to learn. That playground became Fusion Circus. A real simulation(beta) where I could test actual physics — Bosch-Hale fusion reactivity, IPB98 confinement scaling, instabilities that crash plasmas in milliseconds. I wanted to feel what fusion operators feel. And then I realized what I’d built. The more I learned, the more I understood the bottlenecks holding fusion back. The Lawson criterion. Maintaining that critical state where plasma stays hot and dense long enough for fusion to generate Net Energy gain while maintaining device/machine integrity.. It’s a lot. That’s THE challenge. That’s what everyone’s fighting. So I kept going — and recently, since continuing college and taking some math classes, everything clicked even deeper. I started to see materials not just as physical stuff, but as bundles of equations defining their properties. Applying intense heat? Just plug in the right formula for thermal stress, conductivity shifts, or phase changes, and the behavior emerges from the math. That perspective turned the simulator from a learning tool into something even more intuitive and powerful.
Fusion Circus now lets us experience the Lawson struggle firsthand: Heat plasma to 100+ million degrees Fight to maintain confinement as energy escapes Balance heating power against radiation losses Manage instabilities before they crash everything Cross the L-H transition into high confinement mode Suppress ELMs before they destroy your divertor Stay below Greenwald density limit Keep beta under Troyon limit or trigger disruption Protect components from heat flux and neutron damage Shape current profiles to stabilize tearing modes
This is what fusion operators do daily.
The physics is validated against real experiments: JET DTE1 → Q ≈ 0.67 (matches published data) ITER baseline → Q ≈ 8-12 (matches design target) 51-point radial plasma profiles Two-fluid transport (ions ≠ electrons) KSTAR-style AI disruption prediction
Fusion Circus is now in public beta. 28 physics modules. 16 real tokamaks. AI coaching. Tutorials from first plasma to burning plasma. All in your browser. Try it: https://fusion-circus-ultimate.vercel.app/
