About this file
This is an Acceptance Criteria List (ACL) for HBEND Mechanical Components and Sub-Assemblies, prepared by Lawrence Berkeley National Laboratory for the Advanced Light Source (ALS-U) project. Document AL-1835-2074, Revision B, was released January 16, 2026, and specifies quality acceptance requirements for mechanical components and sub-assemblies related to a horizontal bending magnet system.
The ACL establishes 28 acceptance criteria organized into four categories: Receiving (items 1-4), Mechanical Requirements (items 5-24), Functional Performance (items 25-26), and Calibration Documentation (items 27-28). Acceptance criteria require verification of undamaged shipping containers, drop indicators, packing lists, and visual inspection by the LBNL Magnet Production Engineer. Material certification and coordinate measuring machine (CMM) inspection requirements are specified for upper and lower yokes (AISI 1018 Carbon Steel), midplane blocks (1006 steel), base weldment assembly (A36 steel), linkage plates (Stainless Steel 304), and fiducial supports (Stainless Steel 316), with 100% inspection rates for critical components. Machined parts under sub-assembly AL-1828-1699 require CMM inspection of all first articles and 20% inspection for remainder. Certificates of conformance are required for multiple commercial components including drive motors (Kollmorgen AKM32HACSNR-02), linear encoders (Fagor S2ABC50-120-3-A), motor couplings, bearings, linear guides, and adjuster plates. Functional performance acceptance requires the drive actuator to operate through full range with encoder positioning error less than 5 micrometers unloaded, and perform 1-millimeter steps under 2,000±100 newton load with identical positioning accuracy. All calibration records for CMM and torque wrenches, along with complete documentation, must be uploaded to Windchill.
