Diagnostics on Yang accelerator for Z-pinch experiment

This paper describes the diagnostics developed in recent years for gas-puff and wire array Z-pinch experiments performed on Yang accelerator (peak current 1.2 MA, rise time 85 ns). An eight-channel Dante spectrometer and a scintillator X-ray power meter were used to measure the radiation power, energy and sub-keV power spectra of soft X-ray. Two crystal spectrometers (elliptically and convex cylindrically curved) were employed to obtain the plasma parameters from the line spectra in keV range. A transmission grating spectrometer was fabricated to measure the soft X-ray spectra in sub-keV range. An X-ray framing camera, a multi-channel grazing incidence pinhole X-ray camera and a laser differential interferometer were used to obtain the image and electron density of the imploding plasmas. T
