Marx Generator and Reflex Triode based High Power Pulsed Microwave Source
نویسندگان
چکیده
A compact repetitive Marx generator and a High Power Microwave (HPM) source based on a matched reflex triode has been developed and tested. The Marx generator rated at 1 kJ, 300 kV, 12 kA, 10 Hz, is suitable to drive the reflex triode directly. Bipolar charging of the Marx generator has been used to get lower system inductance and consequently faster output rise time with relatively low charging voltage. Inductive charging of the Marx generator capacitors using a capacitor charging power supply has been used to make the system repetitive and enhance the system efficiency as compared to resistive charging. The Marx generator has been characterized using aqueous resistive load and the reflex triode vircator. Experiments have been conducted using the Marx generator and reflex triode system to generate intense relativistic electron beams and high power microwaves.

متن کاملStudy on Decomposition of Indoor Air Contaminants by Pulsed Atmospheric Microplasma
Decomposition of formaldehyde (HCHO) by a microplasma reactor in order to improve Indoor Air Quality (IAQ) was achieved. HCHO was removed from air using one pass through reactor treatment (5 L/min). From an initial concentration of HCHO of 0.7 ppm about 96% was removed in one pass treatment using a discharge power of 0.3 W provided by a high voltage amplifier and a Marx Generator with MOSFET s...
