a Schematic of a surrogate dense-plasma object consisting of a Cu-doped CH plasma layer for spectroscopy. b The predicted Kα emission signal from the doped Cu layer of mass density of ρ = 20 g cm−3 and kT = 200 eV, by three different models: VERITAS (blue solid), collision radiative equilibrium (CRE) models with continuum lowering of Stewart–Pyatt (green long dash) and Ecker–Kroll (black dash-dotted). c The predicted 1s—2p absorption feature from the doped Cu layer at mass density of ρ = 20 g cm−3 and temperature kT = 300 eV.
