Numerical evaluation of AC losses in an HTS insert coil for high field magnet during its energization
K. Kajikawa, S. Awaji, K. Watanabe
AC losses in a high temperature superconducting (HTS) insert coil for a 25-T cryogen-free superconducting magnet are numerically calculated during its energization, assuming slab a…
A Simple Method to Eliminate Shielding Currents Generated when Magnetization is Perpendicular to Superconducting Tapes Wound into Coils
Kazuhiro Kajikawa, Kazuo Funaki
Application of an external AC magnetic field parallel to superconducting tapes helps in eliminating the magnetization caused by the shielding current induced in the flat faces of t…
Hysteretic ac loss of polygonally arranged superconducting strips carrying ac transport current
Yasunori Mawatari, Kazuhiro Kajikawa
The hysteretic ac loss of a current-carrying conductor in which multiple superconducting strips are polygonally arranged around a cylindrical former is theoretically investigated a…
Hysteretic ac loss of superconducting strips simultaneously exposed to ac transport current and phase-different ac magnetic field
Yasunori Mawatari, Kazuhiro Kajikawa
A simple analytical expression is presented for hysteretic ac loss of a superconducting strip simultaneously exposed to an ac transport current and a phase-differen…
Alternating current loss in radially arranged superconducting strips
Yasunori Mawatari, Kazuhiro Kajikawa
Analytic expressions for alternating current (ac) loss in radially arranged superconducting strips are presented. We adopt the weight-function approach to obtain the field distribu…
