soldering of bi 2223 ag high temperature superconducting tapes with sn pb bi ag alloy paste
Physica C-superconductivity and Its Applications, 2010Co-Authors: Zou Guisheng, Wu Aiping, Bai Hailin, Ren JialieAbstract:Abstract Soldered joints of Bi-2223/Ag-sheathed high temperature superconducting multifilamentary tapes were fabricated using 63 wt.%Sn–34 wt.%Pb–1 wt.%Bi–2 wt.%Ag paste. The soldered joints were observed by scanning electron microscope (SEM) and X-ray diffraction (XRD). Moreover, the electrical properties of joints were evaluated by current–voltage curves, and the tensile strengths of the joints were also tested. The results show that the soldered joint consists of Ag sheath – Ag 3 Sn compound layer – PbSn 2 and Ag 3 Sn solder layer – Ag 3 Sn compound layer – Ag sheath. The joints are obeyed with Ohms Law and the magnitude of the joint resistance, which deceases with the increase of the overlap length, can reach the order of 10 −8 Ω. The tensile strength of the joints with a brittle fracture mode is a little lower than that of the original tapes.

nonlocal Ohms Law plasma resistivity and reconnection during collisions of magnetic flux ropes
The Astrophysical Journal, 2018Co-Authors: Walter Gekelman, T Dehaas, P Pribyl, S Vincena, B Van Compernolle, R D Sydora, Shreekrishna TripathiAbstract:The plasma resistivity was evaluated in an experiment on the collision of two magnetic flux ropes. Whenever the ropes collide, some magnetic energy is lost as a result of reconnection. Volumetric data, in which all the relevant time-varying quantities were recorded in detail, are presented. Ohm's Law is shown to be nonlocal and cannot be used to evaluate the plasma resistivity. The resistivity was instead calculated using the AC Kubo resistivity and shown to be anomalously high in certain regions of space.
