About this file
This document contains technical specifications for the manufacture of ConFlat vacuum chambers in two sizes: 8 inches and 10 inches. All components must be fabricated from 316LN stainless steel flanges and 316L or 316LN stainless steel tubing, with an electropolished finish suitable for ultra-high vacuum (UHV) service. Welds must be cleaned, and all parts must undergo UHV service cleaning prior to delivery. Dimensional tolerances are set at +/- 0.060 inches with 1-degree angular tolerance on welded dimensions unless otherwise specified in referenced documentation. Government approval of vendor-supplied drawings is mandatory before manufacturing commences.
Each chamber must meet strict performance and quality standards for acceptance. All deliverables must pass leak-rate testing at less than 10^-9 mbar·L/s at NIST facilities. For both the 8-inch and 10-inch ConFlat chamber variants, dimensions, flanges, and welded mounting points must precisely match attached CAD files, with all tolerances conforming to ranges specified in referenced PDF files. These specifications ensure compliance with ultra-high vacuum system requirements for precision vacuum chamber construction.
