Superconducting (SC) magnets have been used at many accelerators for several decades. In the last several years noticeable progress in the use of SC undulators (SCUs) at the Advanced Photon Source (APS) has taken place. SCUs outperform most advanced permanent magnet-based undulators. This motivated APS to significantly invest in the development of SCU technology. More than a decade of effort by the APS SCU team has culminated in several engineering advances in cryogenic, magnet, and magnet measurement designs applied to SCUs. Successful SCU prototypes led to construction of three SCUs that are currently quite reliably operated at the APS. Two of them are planar SCUs, and one is a helical SCU. Currently as part of the APS-U project, the APS SCU team builds new SCU systems, each comprising two long SC undulators housed in a 5-m-long cryostat. It also works on a quite challenging device, an arbitrary polarizing SCU called SCAPE. At the same time, the APS team, in collaboration with FNAL and LBNL, is working on the development and construction of a planar Nb3Sn SCU and will be collaborating with SLAC on the development of an SCU FEL module.

The Advanced Photon Source Upgrade (APSU) scope for insertion devices (IDs) and ID vacuum systems is extensive. Thirty-five of the 40 straight sections in the storage ring will be retrofitted with new 4.8-meter-long Superconducting Undulators (SCUs) or a mix of new and reused Hybrid-Permanent Magnet Undulators (HPMUs). All 35 ID straight sections will require new vacuum systems and new HPMU control systems. Production is well underway at multiple manufacturing sites around the world for these components. Simultaneously, ID assembly and HPMU tuning is occurring onsite at Argonne National Laboratory (ANL). In addition to component production and assembly/tuning activities, our team also started the ID swap out program at the Advanced Photon Source (APS) in late 2020. This program allows us to remove HPMUs intended for reuse from the APS storage ring and retune them to meet the APSU magnetic specifications to reduce the tuning workload during dark time. These activities have presented technical and logistical challenges that are as unique as the components themselves. Additionally, the ongoing Covid-19 pandemic presented unforeseen challenges that required new work processes to be created to sustain pace and quality of work while maintaining the high workplace safety standards required at Argonne. This paper will summarize the many challenges we encountered during the course of the project and how they were overcome.

The Advanced Photon Source Upgrade (APSU) will include four full length Superconducting Undulators (SCUs). These SCUs require new undulator magnets to achieve the required performance of the new machine. The magnets are fabricated from low carbon steel and wound with NbTi superconductor. To meet the needs of the users of the new machine these magnets will be manufactured in different lengths and magnetic periods to accommodate SCUs in both inline and canted configurations. Because the magnets for the SCUs cannot be shimmed like permanent magnet undulators, they need to have very tight tolerances for the poles and the winding grooves. This poses unique manufacturing and fabrication challenges. This paper will cover the design of the 1.9 m long magnets for the inline SCUs, their measurement data, lessons learned from manufacturing, and an overview of design changes that were made for the magnets to be used in the canted SCU configurations.

MOPB10 The Advanced Photon Source Upgrade (APSU) Superconducting Undulator (SCU) Component Database (CDB) Utilization 44

The Component Database (CDB) is a document management platform created for the use of the Advanced Photon Source Upgrade (APSU) Project. It serves two major functions: (1) a centralized location to link all data relating to field-replaceable upgrade components, and (2) a way to track the components throughout the machine’s 25-year lifetime. There are four (4) Superconducting Undulators (SCUs): two (2) Inline 16.5mm period devices, one (1) Canted 16.5mm period device, and one (1) Canted 18.5mm period device. Throughout the production process for these devices, tracking components between the different designs of SCU’s has proven to be a logistical issue, as there are uniform components among all 4 devices, but many unique components as well. As the scope evolved from a Research and Development (R&D) activity to a production scope, the CDB has been critical in communicating with a growing team, allowing anyone to identify a part or assembly and access all its design and manufacturing data. The 4.8-meter long SCUs are the first of their kind, requiring thorough onsite inspections, intricate assembly procedurals, and approved safety protocols. This is ideal information to document in an electronic traveler (e-traveler), which can then be attached to an item within the CDB. By providing a straightforward process for technicians to follow, the risk of miscommunication and unsafe practices are minimized. The CDB plays a vital role in simplifying and optimizing the transition of the SCU from an R&D unit to a production scope, from procurement to inspection, assembly and installation, and throughout the lifespan of machine maintenance.

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.

A novel technique has been developed to automatically inspect and calibrate the 53 permanent magnet insertion devices in the Advanced Photon Source (APS) storage ring. This technique employs standard frequency domain analysis to create easily identifiable signatures in an actionable format. We will discuss the mechanisms and actions taken behind various observed trends and its application for continuous monitoring and predictive maintenance of these devices. This technique has enabled predictive maintenance and provided new insights into optimizing device performance.
