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.

对于采用超导隧道结（SIJ）器件的核辐射探测器，人们根据开发时间上可能达到的能力付出了最大的研究努力，而辐射的其他原理。本研究期末发展出了利用超导现象进行探测的技术，即TES。将研究成果逐项写出。（1）取得了Nb约瑟夫森结器件的世界纪录，即FWMM 66KeV的Fe-55 X射线5.4KeV。(2)尝试开发一些新设备，特别是在ETL方面，但遗憾的是未能获得FWIIM的世界纪录。示范实验已在SPring8的同步加速器设施中制成。(3)Nb STJ已应用于并联模式以提高效率和尺寸。然后就完成了，而FWMM稍差一些。(4)对Nb STJ探测器制定了性能指标，明确了该探测器目前的目标。
