  1. 785. Sun-Mo-Or1-01: [Invited] Cryogenic irradiation of REBCO tapes for fusion magnets
    David Fischer

    Invited Oral

    Fusion magnets in deuterium-tritium based power plants will experience bombardment by high energy neutrons during operation. This is a particular severe problem for REBCO-based compact high-field fusion reactors. The fusion magnets in these devices will typically be operated at around 20 K and accumulate radiation damage at this very temperature.
    We have commissioned a cryogenic ion...

  2. 554. Sun-Mo-Or1-02: A ladder approach to investigate radiation damage in coated conductors for magnetic confinement nuclear fusion reactors magnets

    Contributed Oral

    Strong efforts to develop magnets for compact fusion reactors using coated conductors (CC) are presently underway. To determine the operational lifetime of fusion magnets, it is necessary to know the effects of radiation damage on the critical current density J$_c$ of the CC. According to plans, fusion magnets will operate between 10 and 30 K in a background field up to 20 T. As portions of...

  3. 104. Sun-Mo-Or1-03: Smart-insulation studies for the TF coils of the EU DEMO reactor
    Dr Mattia Ortino (EPFL-SPC)

    Contributed Oral

    The new type of insulation where metals, varistors on more in general media with a change in resistivity are called “smart insulation”. Among the latter, metal-to-insulator transition (MIT) materials have lately collected interest, since one could get both the advantage of a full insulation during charge/operation (low T) and hot-spot redistribution during a quench (high T).
    In this respect,...

  4. 480. Sun-Mo-Or1-04: DC and AC characterization of DTT superconducting cabled-in-conduit-conductor (CIC) samples
    Chiarasole Fiamozzi Zignani (ENEA)
    06/07/2025, 09:00
    Contributed Oral

    The DTT magnetic system is mainly constituted by the following superconducting coil sets: 18 Toroidal Field (TF) magnets, 6 external Poloidal Field (PF) coils and a stack of 6 independently fed Central Solenoid (CS) modules. The PF coils system, characterized by a full top-down symmetry, is realized in Nb3Sn (PF1 and PF6) and NbTi (PF2, PF3, PF4 and PF5). This work is focused on the SULTAN...

  5. 143. Sun-Mo-Or1-05: Lessons learnt from the HTS Quench Experiment campaign for the EU-DEMO CS design and operation
    Valentina Corato (ENEA)
    06/07/2025, 09:15
    Contributed Oral

    An extensive experimental campaign to study the evolution of the quench in REBCO conductors has been carried out within the EU-DEMO programme, motivated by the use of High Temperature Superconducting (HTS) conductors in the Central Solenoid (CS). The aim was to explore the quench initiation and propagation in different conditions in HTS conductors based on stacked tapes layout. Seven...
