About this file
This is a technical drawing for a Cover, AFE Enclosure component, designated as Drawing Number AL-1899-3881, Revision B, released May 19, 2026. The drawing is the property of Ernest Orlando Lawrence Berkeley National Laboratory (LBNL) and is released on a confidential basis subject to return on demand.
The component is part of the Advanced Light Source project at LBNL's ALS-U Storage Ring. The part has an estimated mass of 0.067 pounds and is manufactured from two materials: ALUM_6061-T6 and ALUM_7075-T6, both requiring electroless nickel plating per ASTM B733 Type II, Class 5, with a minimum thickness of 0.0015 inches. The drawing specifies detailed dimensional tolerances, with unspecified dimensions toleranced to ±0.01 inches for two-place decimals and ±0.005 inches for three-place decimals. All machined surfaces must achieve 63 microinches or better finish per ASME Y14.36M. The part requires 12 through-holes (0.081 inches diameter), 6 holes at 0.084 inches, 2 holes at 0.110 inches, and various other precision-machined features including radii and chamfered edges. Additional requirements include removal of burrs and weld splatter, break edges between 0.020 and 0.25 inches maximum, and laser etching with the drawing number and part serial number in 0.125-inch high characters. The drawing conforms to ASME Y14.5M-2009 dimensioning and tolerancing standards and ANSI/AWS A2.4 welding symbols.
