The simulations of indirect-drive targets for ignition on megajoule lasers.

POSTER

Abstract

The calculations were performed with use of radiation hydrodynamic codes developed in RFNC-VNIITF [1]. The analysis of published calculations of indirect-drive targets to obtain ignition on NIF and LMJ lasers has shown that these targets have very low margins for ignition: according to 1D- ERA code calculations it could not be ignited under decreasing of thermonuclear reaction rate less than in 2 times.The purpose of new calculations is search of indirect-drive targets with the raised margins for ignition. The calculations of compression and thermonuclear burning of targets are carried out for conditions of X-ray flux asymmetry obtained in simulations of Rugby hohlraum that were performed with 2D- SINARA code [2]. The requirements to accuracy of manufacturing and irradiation symmetry of targets were studied with use of 2D-TIGR-OMEGA-3T code. The necessity of performed researches is caused by the construction of magajoule laser in Russia [3].\\[4pt] [1] A.V. Andriyash et al, Physics-Uspekhi, 49, 1084 (2006) \\[0pt] [2] M.N.
