Equivalent-Circuit Method for Analyzing Shielding Current Density in Axisymmetric HTS Film

Autor: Ayumu Saitoh, Teruou Takayama, Atsushi Kamitani, Takazumi Yamaguchi

Publikováno v: IEEE Transactions on Applied Superconductivity. 29:1-4

An equivalent-circuit method is proposed for calculating the shielding current density especially for the case with an axisymmetric high-temperature superconducting (HTS) film. For this case, the behavior of the shielding current density can be expre

Numerical Investigation on Superconducting Linear Acceleration System for Pellet Injection by Using Equivalent-Circuit Model

Autor: Takazumi Yamaguchi, Teruou Takayama, Ayumu Saitoh, Atsushi Kamitani

Publikováno v: IEEE Transactions on Magnetics. 55:1-5

According to a rough estimation, a superconducting linear acceleration (SLA) system might be able to inject a fuel pellet into a core plasma. However, as the consequences of numerical simulations, it was found that the SLA system with only one electr
