I present a joint theoretical and experimental study of near-ambient pressure neon gas interacting with intense X-ray free-electron laser (XFEL) pulses. Many unexpected features are identified with quantum-state-resolved ionization-dynamics calculations in the isolated-atom limit. X-ray-driven formation of hot electron plasma and its non-equilibrium evolution dynamics are investigated in the plasma limit.
