As a high-temperature superconducting (HTS) conductor with a large current capacity applicable to a nuclear fusion experimental device, REBCO (REBa 2 CuO y ) tapes and high-purity aluminum sheets are alternately laminated, placed in a groove of an al

We recently developed and characterized an absorber for millimeter wavelengths. To absorb a millimeter wave efficiently, we had to develop a low reflection and high absorption material. To meet these requirements, we added polystyrene beads in the ep

The presented research aims to establish a theoretical framework for the analysis of the transient behaviour of vapour bubbles resulting from superfluid helium boiling under the conditions of microgravity. As long as the volume of a bubble is small i

As a qualification test of ITER-TF coils, each joint sample was tested prior to manufacture of each TF coil. Eleven joint samples were tested by a conductor test facility with a 9 T split coil. The joint sample comprised two short TF conductors that

In a cold test of the JT-60SA CS1 module, which is composed of six octa-pancake coils and one quad-pancake coil wound with Nb3Sn CIC conductors, the measurement of self-magnetic fields generated by the CS1 module was conducted. As a result, the decay
