  1. 73. Thu-Mo-Po.01-01: Numerical study on Transport AC loss in REBCO-coated conductors with magnetic substrates carrying non-sinusoidal currents
    Dr Wenhao Li (Shanghai University)

    Poster

    In practical high-temperature superconducting (HTS) applications, various harmonics are present, causing the transport current to become non-sinusoidal, which may pose new challenges for controlling AC losses. However, the transport AC loss characteristics of REBCO coated conductor (CC) with magnetic substrates under non-sinusoidal currents are still unclear. In this study, we performed a...

  2. 838. Thu-Mo-Po.01-02: AC Loss Prediction in High-Temperature Superconducting Coils Using a Transformer-Enhanced Surrogate Model
    Dr Linjie Zhou (Wuhan National High Magnetic Field Center, Huazhong University of Science and Technology)

    Poster

    AC losses significantly impact the design and operation of superconducting power devices, making their fast and accurate calculation essential. However, calculating AC losses in high-temperature superconducting coils often requires substantial computational resources. This paper proposes an artificial neural network (ANN) model with a Transformer architecture to calculate AC losses in...

  3. 587. Thu-Mo-Po.01-03: Magnetic field analysis and shielding of components for the Material Plasma Exposure Experiment
    Earle Burkhardt (Oak Ridge National Laboratory)

    Poster

    The magnet system for the Material Plasma Exposure eXperiment (MPEX) provides the necessary field profile to enable rf source and heating along the length in order to meet the desired key performance parameters (KPPs) at the target area. In addition to the magnet system, MPEX has other systems (vacuum, diagnostics, rf source and heating) that operate in close proximity and require shielding...

  4. 645. Thu-Mo-Po.01-04: Insulated HTS pancake AC simulation with different numerical approaches: A-H and H-phi formulations and circuit model
    Rebecca Riccioli

    Poster

    Many experimental and theoretical research studies have been conducted in recent years at the Paul Scherrer Institute (PSI, Switzerland) on the treatment of cancer with proton therapy. The PSI approach is based on fast volumetric rescanning, a technique in which the energy of the beam changes quickly. The development of a suited electromagnetic model to study superconducting magnets for proton...

  5. 162. Thu-Mo-Po.01-05: Non-contact Method for Critical Current Estimation of Superconducting Stacked Cable by Measured Magnetization Loss
    Dr Miyeon Yoon (Tech University of Korea)
    03/07/2025, 08:45
    Poster

    A non-contact method for estimating critical current is proposed, which can be applied to both single superconducting wires and various types of cables with multiple superconducting wires. The authors have previously proposed a method for measuring magnetization loss of a superconducting wire as a means of non-contact estimation of the critical current of a single superconducting wire. Since...
