通过一维条纹相机诊断系统对“聚龙一号”(JL-Ⅰ)四类单层丝阵负载进行了轴向X光辐射测量。由于瑞利-泰勒不稳定性的影响,大部分负载表现出两端发光比中间滞后、阳极端发光比阴极端滞后、阳极端发光总强度弱于阴极端的现象。通过不同类型丝阵对比,对于20mm直径的丝阵,JL-Ⅰ驱动器的匹配负载线质量在0.9mg/cm附近。轴向辐射同步性与辐射功率之间存在相关性。 Axial X-ray radiance measurements were carried out on four single-layer filament arrays of “Julong No.1” (JL-Ⅰ) through a one-dimensional streak camera diagnostic system. Due to the Rayleigh-Taylor instability, most of the loads showed a lag of emission at both ends compared to the middle, with the anode emitting less light than the cathode and the total emission intensity at the anode being weaker than that at the cathode. Through the comparison of different types of filaments, the mass of matching load line of JL-I driver is about 0.9mg / cm for a 20mm diameter filament array. There is a correlation between axial radiation synchronicity and radiant power.
