In this article, a simple and efficient deuterated polyethylene target preparation method is described. The method of convenient removal of the targets from a casting surface without any cryogenic freezing has been adopted. The difference in thermal expansion properties of the target material and casting surface (glass) is utilized. The target thickness was determined from 3 - α energy loss in the prepared targets. The target thickness varies from 100 µg/cm2 to 350 µg/cm2. The thickness variation in these foils was between 4% and 10%. The material retention property of a deuterated foil has been verified by Fourier-transform infrared spectroscopy and an attenuated total reflection method.

一种为核天体物理学相关实验准备氘靶的简单方法

本文介绍了一种简单高效的氘代聚乙烯靶材制备方法。采用了无需任何低温冷冻即可方便地从铸件表面去除靶材的方法。利用目标材料和铸造表面（玻璃）的热膨胀特性的差异。靶厚度由制备的靶中的 3 - α 能量损失确定。目标厚度从 100 µg/cm2 到 350 µg/cm2 不等。这些箔的厚度变化在 4% 到 10% 之间。氘化箔的材料保留特性已通过傅里叶变换红外光谱和衰减全反射方法验证。
