With a pulse current battery on 1030 mu F, 15 kv charge voltage and 4 x 10/sup -9/ H self-inductivity current increase velocities up to 1.5 x 10/sup 12/ amp/sec, maximum currents of 1.2 x 10/sup 6/ amp were obtained in a discharge vessel 38 cm in diameter and 45 cm high. Time-resolved curves of the discharge cross section and time-resolved spectra were derived. The cross section curves show during the ignition path a glow of the total volume from which the contraction phase results after a dark phase. The discharge distributed after the ignition over the total cross section was displaced by the skin effect to the wall and then driven through the Forentz force to the axis. Correspondingly, the selfinduction sinks, after ignition, to a minimum, in order to increase later. The discharge spectrum shows, especially at high pressures, intensive continua during contraction, to which the line emission of the wall material is later added. Probe measurements permit the determination of length of maintenance of the axial symmetry and show the existence of eddy currents in the axis plane within the discharge. Measurements of the magnetic flux show that up to the beginning of the wall separation the largest part of the dischange energy wse used for the building of the magnetic field. Below 6 x 10/sup -2/ Torr x-ray and neutron emissions occur. X-ray emission of 100 kv mean equivalent voltage, in addition to a pulse in the discharge ignition, was recorded during each contraction. A neutron pulse of more than 10/sup 7/ neutrons was observed after the second contraction simultaneously with the spiral instability. (tr-auth)
