For the nuclear radiation detectors using Super Conducting Tunnel Junction (SIJ) Device, the best research efforts have been paid according to those ability possible in the developing time, while the other principle of radiation. detection using super conducting phenomena, that is TES, has been developed in the end of this research periods.The research results are written in an itemized way.(1) The world record for Nb, Josephson Junction Device was obtained, that is the FWMM of 66KeV for Fe-55 X-ray of 5.4KeV.(2) Some new devices have been tried to develop especially in ETL, that is unhappy to be failed to obtain the world record FWIIM.Demonstration experiment has been made in the Synchrotron facility of SPring8.(3) Nb STJ has been applied in the parallel mode to increase the efficiency and size. Then it is completed while the FWMM a little worse.(4) The specifications of performance has been made for the Nb STJ dctections, the present goal for this detector has been clarified.

对于使用超级传导隧道连接器（SIJ）设备的核辐射探测器，最佳的研究工作是根据发展时期的能力支付的，而另一个辐射原则则是根据可能的。在本研究期结束时已经开发了使用超级传导现象的检测。研究结果是以逐项编写的。（1）获得NB的世界记录，即NB，Josephson插口设备，这是FE-55 X射线的66KeV的FWMM，X射线为5.4Kev。 FWIIM。已在Spring8的同步加速器设备中进行了示出实验。（3）NB STJ已在平行模式下应用以提高效率和大小。然后完成，而FWMM稍差一些。（4）已针对NB STJ DCTECTIONS制定了性能的规格，该检测器的当前目标已被阐明。
