Terawatt Power Concentration In Liner Compression Experiments On Module A5-1

In the Liner compression experiments on the Module Angara 5 - 1 instaLLation the energy from a generator with internaL resistance R = 0.04 Ohm was transmitted to the Load through a concentrator being parallelly connected with three - strip magnetically self-insulated lines of 1 nH total inductance. The efficiency of an energy transportation to the inductive loade was shown to be > 70% , the measured leakage current was < 0.5 MA. From the measurements it follows that the main losses occur in the place of lines convolution. The concentration losses can not be explained in frames of the magnetic insulation theory. In mode experiments carried out on MSM installation (V = 100-200 kV, R = 2 Ohm, t = 90 ns) an energy transportation efficiency through strip MITL to an inductive Load with characteristics close to those of concentrator lines. It was observed that when 1 > Imin the losses were connected with a local plasma flows (quick component of plasma, V > 10 7Ws), which can cause the shorting of an interelectrode gap. A geometry concentrator optimization allowed to get I = 4,6 MA in the inductive load that is close to calculated value with a generator forming line voltage V = 1,2 MV.
