摘要:

本文报道了用Fe、Si和Pb三种入射离子测量高能核-核碰撞中总电荷变化碎裂截面的结果。将几组具有不同靶组合的CR 39核径迹探测器以正入射方式暴露于高能加速器束流中,其积分密度约为2000个离子/平方厘米。对核径迹探测器箔进行化学蚀刻,并使用自动图像分析仪系统测量离子径迹。截面的确定是基于束离子及其碎片的电荷识别以及它们通过堆叠的路径的重建。

英文摘要:

We report on the measurements of the total charge changing fragmentation cross sections in high-energy nucleus-nucleus collisions using Fe, Si and Pb incident ions. Several stacks of CR39 nuclear track detectors with different target combinations were exposed at normal incidence to high energy accelerator beams to integrated densities of about 2000 ions/cm^2. The nuclear track detector foils were chemically etched, and ion tracks were measured using an automatic image analyzer system. The cross section determination is based on the charge identification of beam ions and their fragments and on the reconstruction of their path through the stacks.
