ABSTRACT:
An electrical conductor particularly suited for use as a downlead to low temperature devices includes a ceramic honeycomb body having longitudinal channels wherein films of substantially single crystals of a ceramic superconductor are grown. The maximum current carrying capacity of the ceramic superconductor may be oriented parallel to the channels. Square channels arranged in alternating rows of oppositely directed current provide desirable magnetic field cancellations and permit high current flows. A method for making the electrical conductor and a method of extruding the ceramic honeycomb body are also disclosed.
