一、引言1—10μm的Rh,Co和Mo金属箔是核物理研究中常用的核靶,但国内厂家一般不生产这种薄膜,只能由实验室自己制作。滚轧法是获得金属薄膜的有效方法。因Rh,Co和Mo的塑性差,用冷轧技术很难得到<10μm的金属膜。我们采用退火滚轧工艺,成功地为核物理实验制备了上述三种元素的金属薄靶。 I. Introduction 1-10μm Rh, Co and Mo metal foils are the nuclear targets commonly used in nuclear physics research. However, domestic manufacturers generally do not produce such films and can only make them by the laboratories themselves. Rolling method is an effective method to obtain the metal film. Due to the poor plasticity of Rh, Co and Mo, it is difficult to obtain a metal film of <10 μm by the cold rolling technique. We use the annealing rolling process, successfully prepared for the nuclear physics experiments of these three elements of thin metal target.
