Laser-driven implosion experiments using DT-gas-filled spherical glass-shell targets are described. Neutron yields to 5 x 107 are produced from implosions of small ( - 55-11m-diameter) tarots spherically illuminated with an on-target laser power of 0.4 terawatt. Nuclear reaction product diagnostics, X-ray pinhole photographs, fast-ion spectra and X-ray measure-ments are used in conjunction with hydrodynamic computer code simulations to investigate the implosion phenomenology as well as the target coronaevolution. Simulations using completely classical effects are not able to descri by the full rang f experimental data. Electron or radiation preheating may be required to explain some implosion measurements.
