For a scale-up of an electroporation device for mash an existing design for a Marx generator equipped with spark gap switches has been improved to allow for a higher pulse repetition rate and a synchronized operation of two Marx generators charged by a single high-voltage power supply. As the pulse repetition rate of spark gap switches is limited due to the time required to remove charged particles and debris from the inter-electrode area, each spark gap has been equipped with a nozzle to guide the gas towards the gap and, hence, increase the gas flow between the electrodes. A pulse repetition rate of 38 Hz has been achieved. Synchronized operation of Marx generators feeding one electroporation chamber enables to overcome limitations in power due to the circuit inductance. A trigger circuit to trigger the generators by overvolting the first spark gap has been set up and tested successfully. In the talk selected design details and results will be presented.
