Abstract
A spherical-implosion platform diagnosed with the "beamlets"scattered-light detector provides high sensitivity to the impact of plasma screening on inverse bremsstrahlung absorption. Contrary to the more restrictive screening length suggested previously [D. Turnbull et al., Phys. Rev. Lett. 130, 145103 (2023)0031-900710.1103/PhysRevLett.130.145103; D. Turnbull et al., Phys. Plasmas 31, 063304 (2024)1070-664X10.1063/5.0203446], the beamlets data indicate that the electron-only Debye length is the relevant screening length for high-density inverse bremsstrahlung absorption. Using the updated absorption model, we simulate the OMEGA direct-drive inertial confinement fusion implosion database and show that bang times are well reproduced without any ad hoc multipliers.
