Basic Fusion Principle ⚛️
The most common fusion reaction under development is:
D + T -> ^4He + n + 17.6\ MeV
Where:
D = deuterium (hydrogen 1 isotope 1+ 1= )
T = tritium (hydrogen 1 isotope 2+ 1= )
He = helium nucleus produced
N = neutron released
MeV = enormous energy released
⸻
Why Fusion Releases Energy
Small atomic nuclei have strong nuclear attraction.
When fused:
a tiny amount of mass converts into energy
Einstein’s relation:
E = mc^2
Even tiny mass differences produce huge energy.

Why Plasma Is Difficult
No solid material can touch plasma at fusion temperatures.
If plasma contacts reactor walls:
walls melt
plasma destabilizes
So reactors use magnetic confinement.
⸻
Magnetic Confinement 🧲
Charged plasma particles follow magnetic field lines.
Powerful superconducting magnets trap plasma away from reactor walls.
This creates a magnetic “bottle.”
⸻
Tokamak Reactors 🌀
Tokamaks are currently the leading fusion reactor design.
Shape:

plasma circulates continuously inside magnetic field chamber
