利用脉冲强磁场测量超导材料的H_（c2）和J_c（H）

The Measurement of the H_(c2) and J_c (H) of Super Conductor Material Using StrongMagnetic Field of Pulse

提出了利用脉冲强磁场对超导材料Ｈ_（ｃ２）和Ｊ_ｃ（Ｈ）的测量方案，并研制出了测试装置。对ＮｂＴｉ、Ｎｂ_３Ｓｎ、Ｎｂ_３Ｇｅ及掺ＴｉＮｂ_３Ｓｎ等超导材料的Ｈ_（ｃ２）和Ｊ_ｃ（Ｈ）进行了测量，得到了理想的测试结论和有益的测试经验。

This paper is concerned with the measurement of the H_(c2) and J_c(H) of super conductor material using strong magnetic field of pulse.A programme of measurement is put forward and a set of measurement installation has been made.Using this installation,the H_(c2) and J_c(H) of some kinds of super conductor materials,such as NbTi,Nb_3Sn,Nb_3Ge and mixing Ti Nb_3Sn,have been measured. Some ideal measuring conclusions and valuable experiences are obtained.
