【摘要】：碳沉积效应普遍存在于核物理实验中,对低能核反应实验有很大影响。本工作在反应靶前后加不同电压,利用~(12)C束流持续轰击~(13)C靶,研究了~(12) C有效厚度的变化。测量结果表明,碳沉积量与束流轰击时间呈正比。本文分析了碳沉积的成因,研究了降低碳沉积效应的有效实验方法,可为相关实验提供参考。
[Abstract]:Carbon deposition effect exists in nuclear physics experiment and has great influence on low energy nuclear reaction experiment. In this work, the effective thickness of ~ (12) C is studied by continuous bombardment of ~ (13) C target with different voltages before and after the reaction target. The results show that the amount of carbon deposition is proportional to the beam bombardment time. In this paper, the origin of carbon deposition is analyzed, and the effective experimental method to reduce the carbon deposition effect is studied, which can be used as a reference for the relevant experiments.
