薄膜技术在原子核物理实验中应用很广。由于核物理实验的特殊要求,在制备技术上与一般制膜技术有所不同,它吸取各种类型薄膜制备的某些特点,发展成独特的核物理薄膜制备工艺。一、薄膜在核物理实验中的应用薄膜在核物理实验中有着广泛的应用,通常用作为核反应实验的靶核、气体靶薄窗、放射源和靶基衬等等。仅以核反应用的靶核为例,因研究对象不同,对薄膜的要求也不一样,在原子核结构研究中需要对一系列元素制成各种薄膜。例如,在核反应实验中,产生(p,n)
Thin film technology is widely used in nuclear physics experiments. Due to the special requirements of the nuclear physics experiment, it differs from the general film making technology in the preparation technology. It absorbs certain characteristics of various types of film preparation and develops into a unique nuclear physical film preparation process. First, the application of thin film in nuclear physics experiments Film has a wide range of applications in nuclear physics experiments, usually used as the target of nuclear reaction experiments, gas targets thin windows, radioactive sources and the target substrate and so on. Only target nuclei for nuclear reaction, for example, because of the different subjects, the requirements of the film is not the same, in the nuclear structure of a series of elements need to make a variety of films. For example, in a nuclear reaction experiment, (p, n)
