ICF靶丸氘氚总量非破坏性荧光测量法

NONDESTRUCTIVE FLUORESCENCE METHOD FOR MEASUREMENT OF DT IN ICF TARGETS

介绍了惯性约束聚变（ＩＣＦ）研究中，氘氚（ＤＴ）气体燃料靶丸中的氚总量监测新方法——可见光荧光法。该方法是一种非破坏性测量技术，不但适用于直接驱动的内爆靶丸，而且也适用于间接驱动方式下的各种空腔靶现场监测。给出了１９９２年“神光”装置内爆靶丸的现场监测结果，并给出了该方法用于绝对测量时需考虑的因素以及刻度因子。

This paper presents the visible fluorescence method for the measurement of the total tritium quantity in ICF target.As anondestructive method,it may be used not only in the measurement of direct drive targets,but also in the monitoring of wide variety of indirect drive cavity targets.Basing on the practically measuring results of obtained on“shenguang” in 1992,this paper gives atentative plan for application of this method in the measurement of DT quantity in plastic targets and the scale factors which are needed in the case of absolute measurement,especially the importance and necessary of development of high sensitivity fluorescence negative or detectors.
