3. 3 Introduction

4. 4 Nuclear Binding Energy

5. 5Plasma SolidLiquidPlasmaGas ; Freely moving charged particle : ions, electrons.

6. 6 Conditions for Fusion 1) Low Temperature 2) High Temperature HeatGarbage Coloumb Foce !!

7. 7 Conditions for Fusion 1)Lawson’s criterion for Fusion ( Deuterium-Tritium fusion) 2) Creating the conditions for Fusion n : ion density, τ : confinement time

8. 8 Inertial Confinement Fusion This is why we call this as “Inertial Confinement Fusion” Δt ~ 10^-11 to 10^-9 s

9. 9 Heating (Neutron beam) hydrogen gas Magnetic Confinement Fusion
