    In developing large-scale next-generation superconducting radio frequency (SRF) linear accelerators using superconducting films on Cu, the design and development of dissimilar welding and joining metals, such as Cu to Inconel, stainless steel, and Nb, are essential. In this talk, we present the development of procedures for electron-beam welding of Cu-Inconel 625 and evaluation of the...

    Contributed Oral

    An integrated computational model based on a multiscale modeling approach was developed to utilize niobium sheets in forming processes required for high-performance superconducting radio frequency (SRF) cavities. The effects of microstructural features, such as crystalline texture and grain morphology in polycrystalline niobium, on mechanical properties were evaluated based on crystal...

    Contributed Oral

    Transition niobium (Nb) metal has been widely accepted in superconducting technology due to its strong isotropic superconductivity. Its high mechanical formability allows the application of the radio frequency (RF) resonator (cavity) by fabricating a complex device form. The residual resistivity ratio (RRR: 300K/10K) is used to define the purity of superconducting Nb. To date, high RRR Nb (>...

  4. 375. M1Or1A-04: Development of thermal joints for conduction-cooling applications
    Jacob Lewis (Old Dominion University)
    5/19/25, 10:15 AM
    Contributed Oral

    Adequate heat transfer is essential for components and systems that operate in cryogenic environments. In conduction-cooling applications, bolted joints are commonly employed to facilitate the heat transfer between the devices and cryocoolers. The performance of these joints is dependent on a multitude of factors such as material properties, surface topography, pressure distribution, and the...
