| Popis: | A novel technique toward fabricating high-current-carrying MgB2-based superconducting joints employing simple groove-rolling method has been described in this paper. Under this investigation, a superconducting joint of MgB2 monofilaments has been prepared using an in situ powder and a groove roller following a particular sequence. It has been observed that the critical current in the self-field has degraded by 9.2% or less when compared with the normal monofilamentary MgB2 samples without joints prepared in an identical fashion. These fabricated joints have demonstrated impressive current-carrying capabilities of ∼343 A at 21 K in the self-field. Joint fabrication details, testing methodology, results obtained, and probable reasons toward obtaining enhanced critical current characteristics have been described in detail in this paper. |
