Challenges and opportunities of srf theory for next generation particle accelerators
Alex Gurevich, Takayuki Kubo, James A. Sauls
We suggest a program to establish theoretical performance limits of srf cavities using modern theories of nonequilibrium superconductivity under a strong electromagnetic field. The…
Large-gap magnetic topological heterostructure formed by subsurface incorporation of a ferromagnetic layer
Toru Hirahara, Sergey V. Eremeev, Tetsuroh Shirasawa +17
Inducing magnetism into topological insulators is intriguing for utilizing exotic phenomena such as the quantum anomalous Hall effect (QAHE) for technological applications. While m…
Multilayer coating for higher accelerating fields in superconducting radio-frequency cavities: a review of theoretical aspects
Takayuki Kubo
Theory of the superconductor-insulator-superconductor (S-I-S) multilayer structure in superconducting accelerating cavity application is reviewed. The theoretical field limit, opti…
Vortex-penetration field at a groove with a depth smaller than the penetration depth
Takayuki Kubo
Analytical formula to evaluate the vortex-penetration field at a groove with a depth smaller than penetration depth is derived, which can be applied to surfaces of cavities or test…
Superconducting nano-layer coating without insulator
Takayuki Kubo
The superconducting nano-layer coating without insulator layer is studied. The magnetic-field distribution and the forces acting on a vortex are derived. Using the derived forces,…
Review of the multilayer coating model
Takayuki Kubo, Yoshihisa Iwashita, Takayuki Saeki
The recent theoretical study on the multilayer-coating model published in Applied Physics Letters [1] is reviewed. Magnetic-field attenuation behavior in a multilayer coating model…
