Multi gap switch for Marx generators

Summary form only given, as follows. The report presents new gas switch for Marx generators with by polar charging up to 100 kV. The trigger electrode divides the switch into two parts (positive and negative), each of these parts includes three intermediate electrodes. The charge voltage between the intermediate electrodes is evenly distributed by corona discharge. This allows to obtain safe operation of the switch being filled with air at a pressure up to 3 atm. The report presents the design of the switch and test results on a test bed (32 kJ, 320 kA) and in the Marx generator.
