Evolution of light ion driven fusion power plants leading to the LIBRA-SP design

摘要: The use of light ion or electron beams to compress matter the densities required for fusion has been proposed more than 20 years. In past ten years, a series beam power plant conceptual designs have published under generic name LIBRA. Considerable advances in both physics and technology allowed major improvements from design performance earliest LIBRA 330 MW{sub e} recent 979 LIBRA-LiTE, 1000 LIBRA-SP reactors. declassification target allows realistic spectra, gains, injection parameters be analyzed. pulsed driver matured point that Helia induction can tested laboratory single pulse conditions confidently extrapolated repetition rates.
