The implosion of neon-filled glass microballoons has been examined via numerical simulations using a one-dimensional Lagrangian hydrodynamic code. Comparison has been made to experiments performed on a four-beam neodymium glass laser system using an array of diagnostics including X-ray pinhole cameras and soft-X-ray spectrometers. Interpretation of the results obtained here leads to the conclusion that the electron thermal transport is strongly inhibited and that energy transport is dominated by suprathermal electrons producing an explosive pusher implosion.
