TI - The Advanced Photon Source Upgrade (APSU) Straight Section Vacuum Systems First Article Fabrication J2 - Proc. of MEDSI2020, Chicago, IL, USA, 24-29 July 2021 CY - Chicago, IL, USA T2 - Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation T3 - 11 LA - english AB - The Advanced Photon Source Upgrade (APSU) includes 40 straight sections, 35 of which will be outfitted with Superconducting Undulators (SCUs) or Hybrid-Permanent Magnetic Undulators (HPMUs). The vacuum systems for these devices are primarily fabricated from aluminum extrusions and are required to provide Ultra-High Vacuum continuity between storage ring (SR) sec-tors for a nominal distance of ~5.4 meters. Each vacuum system has unique fabrication challenges, but all first article (FA) components have been produced successfully. The FAs arrived onsite at ANL installation-ready, but have undergone functional testing activities to verify the production and vacuum certifications. The Insertion Device Vacuum Chamber (IDVC), used in HPMU sec-tors, is produced by SAES Rial Vacuum (Parma, Italy). The SCU vacuum system components are produced by two vendors, Cinel Instruments (Venice, Italy) and Anderson Dahlen (Ramsey, MN, USA). Based on the reliable outcomes and lessons learned from the FAs, production of the straight section vacuum systems is underway.
