Superconductors for fusion: a roadmap
/ Mitchell, Neil (Euratom, St. Paul Lez Durance) ; Zheng, Jinxing (Hefei, Inst. Plasma Phys.) ; Vorpahl, Christian (EFDA-CSU, Garching) ; Corato, Valentina (ENEA, Frascati) ; Sanabria, Charlie (Unlisted, US) ; Segal, Michael (Unlisted, US) ; Sorbom, Brandon (Unlisted, US) ; Slade, Robert (Unlisted, GB) ; Brittles, Greg (Unlisted, GB) ; Bateman, Rod (Unlisted, GB) et al.
With the first tokamak designed for full nuclear operation now well into final assembly (ITER), and a major new research tokamak starting commissioning (JT60SA), nuclear fusion is becoming a mainstream potential energy source for the future. A critical part of the viability of magnetic confinement for fusion is superconductor technology. [...]

Superconducting Detector Magnet for BabyIAXO
/ Bykovskiy, Nikolay (CERN) ; Dudarev, Alexey (CERN) ; Pais Da Silva, Helder (CERN) ; de Sousa, Patricia Borges (CERN) ; Mentink, Matthias (CERN) ; Ten Kate, Herman H J (CERN)
BabyIAXO, a 20 m-long telescope aiming at the search for solar axions, is planned since late 2017 as a smaller scale but fully functional demonstrator of the International Axion Observatory (IAXO). It essentially comprises a superconducting magnet, optics and X-ray detectors, installed on a Sun-tracking drive system providing rotation and tilting of the detector. [...]

Axions are a natural consequence of the Peccei-Quinn mechanism, the most compelling solution to the strong-CP problem. Similar axion-like particles (ALPs) also appear in a number of possible extensions of the Standard Model, notably in string theories. [...]

Mechanical Design and Analysis of the Baby-IAXO Magnet Cold Mass, Cryostat and Support System
/ Pais Da Silva, Helder (CERN) ; Bykovskiy, Nikolay (CERN) ; Borges de Sousa, Patricia (CERN) ; Dudarev, Alexey (CERN) ; Ten Kate, Herman H. J. (CERN)
According to the so-called Primakoff effect, axions and axion-like particles can transform into photons in the presence of a strong magnetic field. To continue the search for these hypothetical particles, a new helioscope called the International Axion Observatory IAXO, and its subscale but fully functional demonstrator Baby-IAXO, are being designed.

Demonstration of engineering current density exceeding 1 kA mm$^{−2}$ in ultra-thin no-insulation, soldered coil windings using NbTi/Cu wires with CuNi cladding
/ Bykovskiy, N (CERN) ; Kaal, S (CERN ; Twente U., Enschede) ; Dudarev, A (CERN) ; Mentink, M (CERN) ; ten Kate, H H J (CERN ; Twente U., Enschede)
The no-insulation, or more precisely, controlled-resistance coil winding method, nowadays being exclusively used for high-temperature superconducting solenoids, has proven its effectiveness for improving quench protection. When considering low-temperature superconductor magnet technology, which is mostly focused on stability and training issues, controlled-resistance insulation windings are directly addressing these aspects as well.

Quench protection of the BabyIAXO magnet
/ Bykovskiy, N (CERN) ; Dudarev, A (CERN) ; Silva, H (CERN) ; ten Kate, H H J (CERN)
BabyIAXO, a 20 m-long twin-bore helioscope aiming for search of axion like particles, is currently in the engineering design phase and its construction is to be completed within the next 4 years. In addition to X-ray detectors and focusing optics, the system is equipped with a 50 MJ magnet with a common coil layout, containing two 10 m-long NbTi flat racetrack coils cooled by a group of cryocoolers.

Thermal analysis and cryogenics of the Baby-IAXO magnet
/ Silva, H F P (CERN) ; Dudarev, A (CERN) ; Bykovskiy, N (CERN) ; de Sousa, P Borges (CERN) ; ten Kate, H H J (CERN)
Baby-IAXO is a new helioscope, a demonstration version of the proposed full-size IAXO, the International Axions Observatory. It is currently under design and once installed it will search via the Primakoff effect for axions or axion-like particles (ALPs) originating in the Sun. [...]
