About this file

Written by GovTribe AI ·

This is a Bill of Materials (BOM) document for the SR Alignment System, which is a component of the Advanced Light Source (ALS-U) Storage Ring girder assembly at Lawrence Berkeley National Laboratory.

The document lists 15 primary line items and multiple sub-assemblies required for the SR Alignment System, with detailed specifications for each component. Key items include SR plinth studs (M20), thrust bushings (lockdown and alignment versions), magnetized neodymium magnets, fasteners (M24 and M10 specifications), an SR raft alignment pusher block assembly, alignment plates for X and Z-axis adjustments, and various boss covers. The BOM identifies both custom-fabricated parts (designated with AL part numbers) and commercial off-the-shelf (COTS) items (designated with HW part numbers sourced from McMaster-Carr). Each line item specifies the part number, revision level, release date, quantity per raft kit, and McMaster-Carr part numbers where applicable. The document was officially released by the Lawrence Berkeley National Laboratory Document Control Center on May 18, 2026, with revision level B, and includes authorship by D. Munson, A. Gestopa, and S. Nguyen. The BOM supports the procurement and assembly of multiple girder units for the ALS-U Storage Ring project.
