Abstract

Abstract

Axial X-ray radiations of four types of wire-arrays were diagnosed via 1-D streak camera system on JL-Ⅰ. Because of the influence of Rayleigh-Taylor instability, wire-arrays mostly had the behavior that X-ray rose up later near both cathode and anode than that of the middle, X-ray near anode rose up later than that of cathode and the intensity of X-ray close to anode seemed weaker than that of cathode. With the comparison of different types of wire-arrays, the optimized mass per unit length of a 20 mm diameter wire-array on JL-Ⅰ was about 0.9 mg/cm. Further, there was a correlation between axial radiation synchronization and radiation power.
