The X-ray radiation properties of titanium wire X-pinch are investigated on the Yang accelerator at 500800 kA peak current with a rise time of about 80 ns. The radiation power, spectrum and source size of the X-pinch X-ray source are measured and analyzed using X-ray diodes, a transmission grating spectrometer, a crystal spectrometer and a slit camera. The hot dense spot smaller than 15 m emits 1 J of X-ray with an FWHM of 200 ps and a peak power of 1.5 GW distributed in the range of 14 keV. A method to efficiently generate a single X-ray pulse during the X-pinch implosion is demonstrated. The X-pinch presented here is useful for imaging the early stage interior structure of Z pinch as a backlight source.
