Electromagnetic implosions of 20hyphen;cm radius, 2hyphen;cm tall, few centimeter thick gas rsquo;rsquo;shellsrsquo;rsquo; using a 2hyphen;MA, 80hyphen;kV, 0.8hyphen;mgr;sec capacitor bank have been conducted. Implosion velocities gsim;100 cm/mgr;sec and implosion kinetic energies as high as sim;12 kJ, which is sim;17percnt; of the 70hyphen;kJ stored energy in the capacitor bank, have been achieved. Photon yields gsim; 1 kJ above 150 eV and neutron yields sim;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.
