A compact surge generator for investigation of a fast, linear, pinched discharge using only moderate energy storage is described. The technique of construction using an explosive switch to obtain low inductance, and the method of measuring current are discussed. The behaviour of the surge generator when short circuited is determined from the current waveform, and inductance and resistance values are deduced. The inductance and resistance of the switch are much less than those for the whole circuit, with a linear discharge in deuterium.
