Interstellar Propulsion Using Laser-Driven Inertial Confinement Fusion Physics

To transport a spacecraft to distances far beyond the solar heliosphere and around planets of other stars will require advanced space propulsion systems that go existing technological state art. The release fusion energy from interaction two low mass atomic nuclei are able overcome Coulomb barrier offers potential for ∼1011J/g specific implies robotic missions nearby ∼5–10 ly may be possible in trip durations order ∼50–100 years, travelling at cruise speeds ∼0.05–0.15 c. Such would characterised with ∼kN-MN thrust levels, ∼GW-TW jet powers, ∼kW/kg-MW/kg powers. One innovative methods by which reactions can ignited is via impingement laser beams onto an inertial confinement capsule, imploding it thermonuclear state. This paper gives overview physics beam capsule include simulation 1D particle-in-cell code calculation illustrate effects. In application deep missions, various concepts literature discussed, range values assumed pulse frequency, burn fraction areal density appropriate mission presented. It concluded plausible part our future, provided experimental validation ignition on horizon numerical models feasibility developed high fidelity consistent basis.
