    GIT-4 (SNOP4) has been developed using pulsed-power generators with intermediate energy storage and the plasma opening switch. GIT-4 has a primary capacitive energy storage with thirty-six parallel Marx generators located in four oil-filled tanks containing nine generators each. The energy from the Marx generators is transferred to the vacuum insulator through four oil-insulated lines. The intermediate inductive energy storage as well as the plasma opening switch and the load are located in a vacuum chamber of the generator. The discharge circuit has a 4.8-μF capacitance in the primary store and a 0.2-μH inductance in the intermediate store. At 40-80-kV charging voltage the energy in the primary store is 0.54-2.16 MJ, the output voltage is 480-960 kV, and the current rises to 2.35-4.7 MA in 1.54 μs. GIT-4 is being tested with current levels up to 2 MA. The output power of approximately 1.6 TW and voltage of approximately 1.2 MV are achieved at a charging voltage of 40 kV.
