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，人们在研制过程中尽可能地利用其自身的能力进行研究，而对其它辐射原理的研究却很少。在本研究期的最后，发展了一种利用超导现象进行探测的方法，即TES，并将研究结果逐条列出。(1)获得了铌约瑟夫森结器件的世界纪录，即对5.4KeV的Fe-55X射线的FWMM为66 KeV。(2)人们已经尝试开发一些新装置，特别是在ETL方面，他们对未能获得世界纪录FWIIM感到不满。在SPring 8的同步加速器装置中进行了演示实验。(3)铌STJ已被应用在并行模式，以提高效率和尺寸。然后，它是完成，而FWMM有点糟糕。(4)对Nb STJ探测器的性能指标作了规定，明确了该探测器目前的目标。
