Shielding efficiency and E(J) characteristics measured on large melt cast Bi-2212 hollow cylinders in axial magnetic fields
J-F Fagnard, S Elschner, J Bock +3
We show that tubes of melt cast Bi-2212 used as current leads for LTS magnets can also act as efficient magnetic shields. The magnetic screening properties under an axial DC magnet…
Use of 2G coated conductors for efficient shielding of DC magnetic fields
J. -F. Fagnard, M. Dirickx, G. A. Levin +3
This paper reports the results of an experimental investigation of the performance of two types of magnetic screens assembled from YBa2Cu3O7-d (YBCO) coated conductors. Since effec…
Modification of the trapped field in bulk high-temperature superconductors as a result of the drilling of a pattern of artificial columnar holes
Gregory P. Lousberg, J. -F. Fagnard, M. Ausloos +2
The trapped magnetic field is examined in bulk high-temperature superconductors that are artificially drilled along their c-axis. The influence of the hole pattern on the magnetiza…
Magneto-thermal phenomena in bulk high temperature superconductors subjected to applied AC magnetic fields
P Vanderbemden, P Laurent, J-F Fagnard +3
In the present work we study, both theoretically and experimentally, the temperature increase in a bulk high-temperature superconductor subjected to applied AC magnetic fields of l…
Pulsed-field magnetization of drilled bulk high-temperature superconductors: flux front propagation in the volume and on the surface
Gregory P Lousberg, J-F Fagnard, E Haanappel +4
We present a method for characterizing the propagation of the magnetic flux in an artificially drilled bulk high-temperature superconductor (HTS) during a pulsed-field magnetizatio…
Measurement of the magnetic field inside the holes of a drilled bulk high-Tc superconductor
Gregory P Lousberg, Jean-Francois Fagnard, Jacques G Noudem +3
We use macroscopic holes drilled in a bulk YBCO superconductor to probe its magnetic properties in the volume of the sample. The sample is subjected to an AC magnetic flux with a d…
