Temperature Dependance of Propagation Velocity in a Silver Sheathed Bi-family Superconducting Oxid Tape

Bi계 은시스산화물초전도테프의 쿠엔치전파특성의 온도의존성

Owing to the discover of oxide superconducting over critical temperature100K, it is being made experimentally somewhere under the possibility that there is superconducting magnet by cooling liquid nitrogen. The issues of thermal stability and quench process of Low-Tc superconductor has been studied and used application of oxide superconducting magnets. However the quench propagation property of oxide superconductor, especially experimental data about thermal behavior has not been reported yet. Therefore we measured the effect of temperature dependance of quench propagation velocity, Vq, by using the short samples made up of silver sheathed Bismuth-family (2223phase) superconducting oxide tape.
