The glow discharge cleaning(GDC) is widely used for the fusion devices such as JT-60U, JET and TFTR at present. The HL-1M Tokamak has a single shell of the vacuum chamber liner made of 00Cr18Ni10Ti and graphite. 6％ of the interior wall is covered by the graphite. Two sets of ultra-high vacuum pumping machines are used on HL-1M Tokamak. There are various impurities in the vacuum chamber without cleaning. The metal impurities Cr, Ni comes from the vacuum chamber material. The first wall processing methods such as the siliconization
