摘要
建立了烘烤出气和辉光放电清洗(GDC)出气的物理模型,研究了装置器壁的烘烤出气和辉光放电清洗出气特点。烘烤出气是体出气,出气过程满足扩散方程;GDC出气是溅射脱附过程,它主要是器壁表面的溅射诱导出气。由此分析了HL-1M装置的烘烤出气和辉光放电清洗出气特点,得出了一些经验公式。
The model of out-gassing by baking and glow discharge cleaning （GDC） is set up. The properties of them are studied. Out-gassing by baking is from bulk and it obeys the diffusion equation. Out-gassing of glow discharge cleaning is mainly on surface, it is inducement out-gassing by sputtering. Thus the properties of out-gassing for baking and GDC on the HL-1M tokamak are analyzed. Some empirical formulas are given.
