Özet:

In this study, a high voltage Marx generator is produced in coaxial structure. A literature review is performed and previous studies are examined before production. The structure of the Marx generators developed in these studies, the output voltage amplitude, rise time etc. parameters are examined. Then the production of the generator is started and the output voltage of the generator, capacitor number, stage number and sphere size of the spark gap etc. are identified. Later, the production studies of the generator are started, capacitors are soldered for each stage and sphere electrodes are mounted. Eight stages are produced and these stages are connected with each other. Then the return conductors of the Marx generator are manufactured and connected. After that, power supply of the generator is designed and produced. The connection between the power generator and the Marx generator, the earth connection of the generator are made. Following the completion of the production studies, experimental studies are started. The generator is operated at various voltages and the charging voltage is measured. As a result, some modifications are made for power supply. The charge voltage is determined for the safe operating range and sphere gaps are optimized according to this voltage amplitude. Following the observation of the correct operation of the Marx generator, the measurement system is produced and the output voltage of the generator was measured through a capacitive voltage divider. The amplitude of the output voltage, rise time and fall time are recorded in the oscilloscope. Various load combinations were created with various front resistors and tail resistors, and the measured signals were recorded. In these signals, the effect of resistance change on the output of the Marx generator output was observed
