The highest-performing direct-drive cryogenic implosions to date were conducted on the OMEGA Laser System. Shown here is a plot of the yield versus the areal densities for the OMEGA cryogenic implosions. Data from the 10 July 2018 shots are shown as black circles. The generalized Lawson criterion derived by Chang [P. Y. Chang et al., Phys. Rev. Lett., 104, 135002 (2010)] are scaled to a NIF energy of 1.9 MJ and are shown as curves. The χno α = 1 line represents the onset of ignition in an ICF implosion on the NIF. July cryogenic implosion data have crossed the NIF χno α = 0.8 line and clearly show improved direct-drive implosion performance.
Shown here is the Best Ignition-Scaled Cryogenic Target Performance To Date
