Slide1

Initial irradiation

Target (made of Deuterium-Tritium, DT here) is irradiated by high-energy lasers

Slide2

Compression

Target is compressed thanks 
to plasma expansion

Slide3

Ignition

Target collapses on itself, density in the center skyrockets and temperature reaches 100M°C

Slide4

Combustion

The thermonuclear combustion spreads rapidly, producing large amounts of energy

Inertial Confinement Fusion:
How does it work?

To reach the density and temperature required to trigger an Inertial Confinement Fusion (ICF) reaction, high-energy lasers need to hit a target made of atoms capable of fusion.
