一种制备核天体物理实验用氘靶的简单方法
A simple method to prepare deuterated targets for experiments relevant to nuclear astrophysics
摘要：
在这项工作中，一个简单而有效的薄（$50- 350μg/cm^2$）氘代聚乙烯靶的制备方法。本文介绍了一种不使用任何深冷冷冻而能从铸件表面容易地去除薄靶的方法。利用热膨胀特性的差异将薄膜与载玻片分离。3-使用$α$放射源测量靶厚度。利用衰减全反射（ATR）方法对制备的靶材的材料特性进行了验证。
英文摘要：
In this work, a simple and efficient thin ($50- 350μg/cm^2$) deuterated polyethylene target preparation method is described. The method of easy removal of thin targets from casting surface without using any cryogenic freezing has been described. The difference in thermal expansion properties is used to separate films from glass slides. 3-$α$ radioactive source is used to measure the target thickness. The material property of the prepared targets is verified by Attenuated total reflection (ATR) method.
