    Poster

    MQXFAP1b was the second test of a long prototype quadrupole magnet for AUP which ended with training clearly limited by a single coil (QXFP03). Post testing, an investigation was launched to try and determine what drove the difference in the performance of the limiting coil in comparison to one of the best performing coils (QXFP04). Visual observations were made, followed by electrical...

    Poster

    Complex stress/strain can arise from the winding, cooling down and intense field in YBCO superconducting coils, which can induce maximum internal strain to several thousand micro-strain in coils. Thus, efficient production and operation of YBCO superconducting magnets will benefit from smart sensors that may be embedded within structure without damaging its structural integrity. Currently，most...

    Poster

    The new Nb3Sn superconducting magnet system for a 45 GHz electron cyclotron resonance (ECR) ion source is under developing in the Institute of Modern Physics (IMP). The sextupole coil, which is wound by a single Nb3Sn wire, is indeed a great technical challenge. Because of the complicated technology process and the stress sensitivity of the full-length Nb3Sn sextupole coil, a sextupole...

    Poster

    The Fourth-generation ECR (FECR) ion source Nb3Sn Superconducting Magnet is being developed by Institute of modern physics, Chinese Academy of Sciences. In order to reduce the risk of development, a representative prototype is designed. The FECR prototype consists of two Nb3Sn solenoid coils and six Nb3Sn sextupole coils, This paper reports on the assembly process and cool-down to cryogenic...

  5. 373. Preliminary strain measurement in high field superconducting magnets with fiber Bragg gating (FBG) (WED-PO2-716-07)
    Zhen Zhang (Institute of High Energy Physics, Chinese Academy of Sciences)

    Poster

    High field superconducting magnets sustain large Lorenz force during operation. The superconductors for high field applications like Nb3Sn is strain sensitive, therefore it is essential to measure the strain level in superconducting coils during operation. Compared with traditional approach with resistance stain gauges, Fiber Bragg Grating Sensors (FBG) has significant advantages in high field...

    Poster

    EU DEMOnstration reactor (DEMO) aims towards demonstrating the feasibility of commercial fusion power plant. Various activities are in progress as part of EUROfusion’s framework for the design of DEMO. As part of the mechanical assessment activities, various Finite Element (FE) analysis on these complex systems are performed. Due to the large dimensions of the magnets, a multiscale approach is...
