Abstract:
This process specification is for the process of oxidizing mirror finished (Super #8) 304 stainless steel baffles for Advanced LIGO to provide baffling for stray light beams. A high temperature furnace baking process reduces the reflectivity of the stainless steel baffle @1064nm to approx 12%. It includes material requirements and the process and preparation for oxidation. These baffles are for use in an Ultra-High Vacuum (UHV) system.
