  1. 725. Wed-Af-Po.01-01: EPOS: A Stellarator to use ReBCO High-Temperature Superconductors
    Paul Huslage (Max-Planck-Institute for Plasma Physics)

    Poster

    The EPOS stellarator, a compact device for confining electron-positron plasmas, will leverage high-temperature superconductors (HTS) to generate a highly optimized toroidal magnetic field. To achieve this, we will employ non-planar, non-insulated coils made from rare-earth barium copper oxide (ReBCO) tapes, which enable a 2T magnetic field on axis and a plasma volume of approximately 10L. We...

  2. 615. Wed-Af-Po.01-02: Designing Robust Stellarator ReBCO Coils
    Pedro Gil (Max-Planck-Institute for Plasma Physics, Garching, Germany)

    Poster

    The APEX (A Positron Electron eXperiment) collaboration is developing a “tabletopsized”
    stellarator, EPOS (Electrons and Positrons in an Optimized Stellarator). In this
    work, we present ReBCO non-planar, non-insulated (NI) coils designed to confine pairplasmas
    within a quasi-axisymmetric magnetic field of 2.0 T on axis. The stellarator’s
    small size enhances its utility by reaching higher...

  3. 678. Wed-Af-Po.01-03: Canis: 3x3 array of sub-scale planar coils for the Eos stellarator
    Brian Chen (Thea Energy, Inc.)

    Poster

    The “Canis” 3x3 array of high-temperature superconductor (HTS) planar coils was designed, manufactured, and tested by Thea Energy, Inc to demonstrate the viability of its core technology to generate stellarator magnetic fields for “Eos”, the company’s first integrated fusion system. The Canis 3x3 magnet array demonstrated the ability to create complex magnetic field shapes with sufficiently...

  4. 661. Wed-Af-Po.01-04: Multi-Objective Optimization of C0 Stellarator Coils with Only Planar Segments in DESC
    Egemen Kolemen (Princeton University, Princeton Plasma Physics Laboratory)
    02/07/2025, 14:30
    Poster

    Magnetic confinement fusion devices, such as tokamaks and stellarators, use coils to confine plasma in a toroidal shape. Tokamaks rely on D-shaped pancake coils but also require a toroidal current in the plasma to generate the desired magnetic fields. Stellarators, on the other hand, avoid the need for a plasma current by relying solely on external coils, which leads to complex 3D coil...

  5. 764. Wed-Af-Po.01-05: S.M.A.R.T.: A bold design to achieve aneutronic fusion energy
    Carl Weggel (M.A.G.I.C., LLC)

    Poster

    S.M.A.R.T. promises to be the boldest design to generate aneutronic fusion energy, first as process heat, and then as electricity for the power grid. I propose to incorporate 27 novel features to enable the Toroidal-Field (TF) system--with its brittle ceramic HTS conductor--to survive the peak stresses--and strains--from the (J x B) Lorentz forces generated by a peak ambient field of more...
