Electromagnetic implosions of 20‐cm radius, 2‐cm tall, few centimeter thick gas ’’shells’’ using a 2‐MA, 80‐kV, 0.8‐&mgr;sec capacitor bank have been conducted. Implosion velocities ≳100 cm/&mgr;sec and implosion kinetic energies as high as ∼12 kJ, which is ∼17% of the 70‐kJ stored energy in the capacitor bank, have been achieved. Photon yields ≳ 1 kJ above 150 eV and neutron yields ∼107have been obtained. Gas injection and preionization, current and voltage data, and fast photography data are discussed. Comparison with higher energy foil implosion experiments is briefly discussed.
