X-ray Diagnosis of Z-pinch Implosions of Wire Array Centered by a Deuterated Fiber(In Chinese)

Z-pinch experiments with tungsten wire array and aluminium wire array centered,respectively,by a deuterated fiber(C_8D_8) have been carried out on Qiangguang-1 facility.X-ray radiation power was obtained by an X-ray power meter(XRPM) and soft X-ray images were given by a ten-frame time-resolved pinhole camera.Comparing XRPM's data of both two kinds of loads,tungsten wire arrays with C_8D_8 have a higher record of X-ray power and total radiation energy.The framing images indicate that implosions of tungsten wire arrays with C_8D_8 show a more ideal symmetry than those of aluminium ones.The neutron yield from the D-D reaction reached 1.5×10~9 per shot in a tungsten wire array with C_8D_8 and 3.4×10~8 per shot in an aluminium one.
