热裂解法制备的同位素碳箔和天然碳箔在核物理实验中有多种用途。本文介绍了一种用无油真空抽气系统在金属钽丝上用热裂解法制备这种箔的装置。研究了铝箔的可达厚度、面积、均匀性、纯度和成品率等性能。我们还研究了箔生产过程中的以下问题：当Ta丝温度在开裂过程后降低时，开裂层有时会从丝上断裂成碎片。最终，我们成功地制备了厚度为0.2 ~ 5 mg/cm ~ 2、尺寸为20 × 20 mm ~ 2甚至更大的富集同位素~（12）C薄膜和天然碳薄膜。
Isotopic and natural carbon foils made by thermal cracking method are used for various purposes in nuclear physics experiments. An apparatus equipped with an oil free vacuum pumping system has been constructed to produce such foils on a resistively heated metallic Ta filament by the thermal cracking method. Properties of the foils such as accessible thickness and area, uniformity, purity and yield in the foil preparation were investigated. We also investigated the following issue during the foil production; when the Ta filament temperature was decreased after the cracking process, the cracked layer sometimes broke into pieces from the filament. Eventually, we could successfully fabricate enriched isotopic12C foils and natural carbon foils with thicknesses from 0.2 to 5 mg/cm2and with a dimension of 20 × 20 mm2or even larger.
