About this file
This is a technical engineering drawing for a support bracket component used in the Advanced Light Source (ALS-U) Storage Ring at Ernest Orlando Lawrence Berkeley National Laboratory (LBNL). The document specifies detailed manufacturing specifications for part number AL-1880-8281, revision B, which is an aluminum alloy (5052-H32) support bracket weighing 0.192 kilograms.
The drawing provides comprehensive dimensional specifications in millimeters with U.S. customary unit conversions, including overall dimensions of 266mm length and 231mm width, with multiple hole patterns (8 holes with R3 radius, 4 full radius slots, and 3 holes at 6.60mm diameter with specific tolerances). Manufacturing requirements include surface finishing to 3.2 micrometers or better per ASME Y14.36M, burr removal with 0.25 to 0.75mm chamfer or radius, and permanent part marking per EG-1002-1955 specifications. The drawing was authored by Dennis Li, checked by bholmquist and smyers, and officially released by dgudkov on April 7, 2026. All applicable standards referenced include ASME Y14.5M-2009 for dimensioning and tolerancing, ASME Y14.38 for abbreviations, and ANSI/AWS A2.4 for welding symbols. The document is classified as pre-staging design and released to the LBNL Document Control Center with standard intellectual property protections.
