S-300, new pulsed power installation in Kurchatov Institute, investigation of stable liner implosion

Starting from the beginning of 1996, experiments are being carried out in the Kurchatov Institute, based on the new S-300 machine, to study the stability of magnetic implosion. This installation has been constructed under the support of the Russian Ministry of Science and Technology and also of the French Atomic Energy Commission. The principal scheme is traditional one: Marx generator, intermediate, pulse forming and transporting water lines. By the optimal load and optimized charging voltage, this machine has to provide the total current of 8 modules as high as 6 MA. Heretofore, we operated in a reduced regime, so that the current was up to 4 MA on the load ∼several nH. Some typical oscillograms of the current are shown in Fig.l. The current was measured by the loops established on the input to the concentrator (Iin) and close to the load (Iout). Detailed description of the S-300 construction and features have been done in [1,2].
