Device Engineering and Advanced Physics Research Division

The Device Engineering and Advanced Physics Research Division is involved in the advancement of scientific research into radiation safety and large scale superconducting systems directed towards the realization of a safe and stable fusion reactor. As one of its technologies, research for the improvement of the performance and reliability of the LHD superconducting system is being carried out. Moreover, the Division promotes coordinated research with industrial institutions and applied research for other fields by utilizing mainly the microwave applications and superconductivity engineering.

As a result of research to improve the performance of the LHD, excitation to a higher field was achieved by adopting the subcooling system that has been newly developed. Aiming at the application to large-scale superconducting systems, we are advancing the development of Nb3Sn superconductors jacketed with an aluminum alloy by the FSW (Friction Stir Welding) method. Moreover, we are advancing the measurement of low-level radiation, the separation and collection of hydrogen isotopes, and the influence of electromagnetic radiation, for example, as radiation safety research. Regarding microwave applications, we are advancing the development of a new method of steel manufacturing that causes less damage to the environment by utilizing microwaves that can heat the iron atom and its oxides at a far higher efficiency.
