About this file

This document is an Acceptance Criteria List (ACL) for the SR PTL vacuum chambers as part of the Advanced Light Source Upgrade (ALS-U) project at the Lawrence Berkeley National Laboratory (LBNL).

The ACL outlines the detailed acceptance criteria and inspection procedures for the SR PTL vacuum chambers, including visual, mechanical, magnetic permeability, vacuum, and shipping inspections. It specifies requirements such as surface finish, dimensional tolerances, leak rates, pressure testing, and documentation to be provided. The ACL must be completed for each vacuum chamber before acceptance. This ACL is the authorizing document referenced in the LBNL ALS-U Quality Assurance Plan.
