Development of a new radiation Detector using Super-Conducting Junctions

对于使用超导隧道结(SIJ)器件的核辐射探测器，在研制过程中，一直在根据可能的能力进行最大限度的研究，而另一种辐射原理。本研究期末开展了超导现象探测，即TES。研究成果以分项的方式写成。(1)获得了Nb约瑟夫森结装置的世界纪录，即对于5.4keV的Fe-55 X射线，获得了66keV的FWMM。(2)一些新的装置已经尝试开发，特别是在ETL中，不高兴未能获得FWIIM的世界纪录。在SPring8的同步加速器装置上进行了演示实验。(3)将Nb STJ应用于并行模式，以提高效率和尺寸。(4)制定了NBSTJ探测器的性能指标，明确了该探测器目前的目标。

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.
