摘要：
A laser interferometer gravitational wave detector requires an ultra high vacuum in the tubes in which the laser beams pass. To avoid noise due to scattered light from the surface of tubes, the surface should be treated with "black" coating without increasing the outgassing rate. We found that diamond-like Carbon (DLC) coatings are suitable for this aim. in An outgassing rate of 3 x 10(-9) Pa m(3) s(-1) m(-2) at 50 h was achieved for DLC coatings on SUS304 without baking. This rate was better than the surface of SUS316 with baking. The reflectivity of the DLC surface was 5% at minimum for a laser beam of Nd:YAG (lambda = 1064 nm) which is used as a light source for the gravitational wave detector.) (C) 2003 Elsevier Ltd.
