Primary study on production of keV level characteristic X-radiation via high power Z-pinch on Qiangguang-I generator

The physical mechanism for producing keV level X-radiation via high power Z-pinch and a two-level model for K-shell radiation scaling of the imploding Z-pinch plasma were investigated, and the results of the numerical simulation by the two-level model were given in detail. The performance parameters of Qiangguang-Ⅰ generator for driving Z-pinch loads, the configuration and parameters of double-shell neon gas puff load and aluminum wire array were described, and the experimental arrangement was introduced. The waveform of X-ray measured by special X-ray diode for Qiangguang-Ⅰ with neondouble gas puff indicated that a good result of keV level characteristic X radiation could be obtained when the initial pressure of neon is 0.8 MPa.
