The outline of this chapter is as follows. Section 1.1 introduces the electromagnetic
quantities and basic equations. Next, Section 1.2, we present analytical formulas that also …

We parallelize the LU factorization of a hierarchical low-rank matrix (H-matrix) on a
distributed-memory computer. This is much more difficult than the H-matrix-vector …

We developed a novel software for large-scale electromagnetic field analyses of coils
wound with coated conductors based on current-vector-potential formulation with thin-strip …

Hierarchical Matrix (H-matrix) is an approximation technique which splits a target dense
matrix into multiple submatrices, and where a selected portion of submatrices are low-rank …

A three-dimensional electromagnetic field analysis model was developed to estimate ac
losses in high-temperature superconductor (HTS) coils composing superferric magnets for …

Hierarchical matrices (H-matrices) can robustly approximate the dense matrices that appear
in the boundary element method (BEM). To accelerate the solving of linear systems in the …

We carried out repeated excitation experiments of a test magnet for accelerator applications
of RE-123 coated conductors in order to study its tolerance against ac loss and the stability …

A hierarchical matrix (H-matrix) is an approximated form of a dense matrix, which is derived
from an integral equation with a degenerate kernel. An H-matrix is constructed by …

A cryocooler-cooled high-temperature superconducting magnet was constructed, and it was
tested on the beam line of the heavy ion medial accelerator in Chiba (HIMAC). The magnet …

抄録 High-temperature superconducting (HTS) wires such as those used for Bi-2223 and
REBCO tapes, which are commercially available, are expected to be used in future electric …
