低通量慢中子对Bi系超导体的辐照效应

IRRADIATION EFFECT WITH SLOW NEUTRONS OF LOW FLUENCE ON Bi-BASED SUPERCONDUCTORS

本文研究低通量慢中子对Bi系超导体的辐照效应。实验结果表明:(1)Bi系超导体在适量慢中子辐照后,临界电流密度Jc和零电阻温度Tco都有不同程度提高;(2)低通量慢中子和高通量快中子对Bi系超导体具有相似的辐照效应。

Effect of slow neutron irradiation of low fluence on bismuth-based superconductors is studied. It's shown through experiments that (1) both critical current density J。 and zero-resistance temperature Tc0 are increased, though to different extents, after the Bi-based superconductors were irradiated with slow neutrons to suitable fluence and (2) slow neutrons of low fluence and fast neutrons of high fluence have similar irradiation effects on Bi-based superconductors.
