Analysis of Ar line spectra from indirectly-driven implosion experiments on SGII facility

摘要: This paper reports on the indirectly-driven implosion experiments SGII laser facility in which Ar emission spectrum from Ar-doped D-fllled plastic capsule is recorded with crystal spectrometer. Spectral features of Hefl line and its associated satellites are analysed to extract electron temperature density core. Non local thermal equilibrium (NLTE) collisional-radiative atomic kinetics Strark broadening shape included present calculation. By comparing calculated measured one, core inferred be 700 eV 2:5 £ 10 23 cm i3 respectively. With these values density, neutron yield can estimated agree value magnitude despite very simple model used for estimation.
