Experimental research on Z-pinch at Qiangguang-Ⅰ facility

Experimental research on plasma radiation characteristics and plasma implosion of Kr gas-puff, W wire array, Ne gas-puff and Al wire array Z pinches performed on Qiangguang-Ⅰ pulsed power generator of 1.4~ 2.1 MA current with 80~100 ns rise time is reported. In the experiments, the voltage divider and two Rogowskii coils were used to measure the voltage and the current of diode respectively, a filter-XRD and a scintillator-photodiode detector with even energy respond in the energy region from 100 eV to 1 400 eV were used to measure X-ray waveforms, the Ni-film bolometer was developed for measuring the total soft X-ray energy, the time-resolved X-ray image diagnostic system was developed for recording the imploding process of Z pinches, and an elliptically-curved crystal spectrometer with
