Abstract: AN ELONGATED METALLIC TUBE HAS SECURED THEREIN, WITH SUBSTANTIAL LINE CONTACT, A SHEATHED FILAMENTARY SUPERCONDUCTOR, HAVING AN OUTSIDE DIAMETER MUCH LESS THAN THE INSIDE DIAMETER OF THE TUBE; PREFERABLY THE SHEATH METAL AND THE METAL OF THE TUBE ARE THE SAME (FOR EXAMPLE COPPER, ALUMINUM, OR ALLOYS THEREOF). ACCORDING TO THE METHOD, A LONG BAND IS PROVIDED ALONG THE LENGTH OF WHICH THE SUPERCONDUCTOR IS FIRST BONDED, FOR EXAMPLE BY WELDING, OR FUSING OF THE SHEATH METAL TO THE BAND; THEREAFTER, THE BAND IS FOLDED AND FORMED INTO THE TUBE, THE LATERAL EDGES OF THE BAND BEING SEAMED TOGETHER TO FORM A FLUID TIGHT SEAL FOR EXAMPLE BY WELDING, COLD FLOWING OR THE LIKE.
