  1. Nuclear Fusion Class : Nuclear Physics 1 2005. 12. 7 K.-U.Choi

  2. Outline • Introduction • Theoretical Background • Instruments, Experiments • Data review & Present Status • Summary

  3. Introduction

  4. Nuclear Binding Energy

  5. Plasma ; Freely moving charged particle : ions, electrons. Solid Liquid Gas Plasma

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

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

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

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

  10. hydrogen plasma heating

  11. hot hydrogen plasma heating HIGH

  12. hot hydrogen plasma problem: wall contact! heating HIGH

  13. avoid wall contact with magnetic field hot hydrogen plasma heating HIGH

  14. avoid wall contact with magnetic field hot hydrogen plasma heating HIGH

  15. hot hydrogen plasma heating HIGH end losses problem:

  16. avoid :torus! end losses Magnetic Confinement Simulation

  17. ITER ( International Thermonuclear Experimental Reactor ) Magnets Launcher Vacuum Vessel Thermal Shield

  18. 1010 108 Power station 106 104 102 ITER JET 100 D-T 10-2 fusion power [Watt] D-D 10-4 10-6 2010 2015 1970 1975 1980 1985 1990 1995 2005 2000 Data review

  19. Summary & Outlook • We can expect Nuclear fusion Reactor • We can research Ion Beam nuclear fusion reactor
