μm pulse power source and it's application in Z-pinch diagnosis

This paper presents a microsecond pulse power source with adjusted voltage range (0~120V) and regulative pulse duration (3~14μs), which is used in the measurement of the soft X-ray total energy of high power Z-pinch plasma. By the application of microsecond pulse power source and voltage difference recording method and by the analyses of test circuit, the change of resistance in measurement is considered to be result of the Ni-film bolometer change caused by X-ray irradiation.
