论文摘要
已经采用了电阻加热和机械滚动方法来制备116SN（〜380μg/cm2），124SN（〜400μg/cm2）和112SN（1.7 mg/cm2），120SN（120SN（1.6 mg/cm2）的较厚的箔纸），124SN（〜400μg/cm2），制备同位素富集的薄材料箔。在制造薄靶的几个挑战中，准备富含材料的富集靶标，用于薄靶标的释放剂和分离沉积材料的分离是一项挑战。已经使用241AMα-SORCE测量了目标的均匀性。 NaCl已被用作释放剂，以制备薄靶标。这些靶标已成功地用于VECC的核物理实验。
Resistive heating and mechanical rolling methods have been employed to prepare isotopically enriched thin target foils of 116Sn (~380 μg/cm2), 124Sn(~400 μg/cm2) and thicker foils of 112Sn (1.7 mg/cm2),120Sn (1.6 mg/cm2),respectively. Preparation of enriched targets with small amount of material, selection of releasing agent for thin targets and separation of deposited material insolvent were among the several challenges while fabrication of the thin targets. Uniformity of the targets has been measured using 241Am α-source. NaCl has been used as releasing agent in preparation of the thin targets. These targets have been successfully used in nuclear physics experiments at VECC.
