Development of a new radiation Detector using Super-Conducting Junctions

对于采用超导隧道结（SIJ）装置的核辐射探测器，在研制时间内根据其能力尽了最大的努力，而另一方面则采用了辐射原理。利用超导现象的探测，即TES，在本研究末期得到了发展。研究结果是逐项写的。(1)获得Nb， Josephson结器件的世界纪录，即Fe-55 x射线的FWMM为66KeV （5.4KeV）。(2)尝试开发了一些新装置，特别是在ETL中，遗憾的是未能获得世界纪录FWIIM。在SPring8同步加速器装置上进行了演示实验。(3)采用Nb - STJ并联方式，提高了效率和尺寸。然后在FWMM稍微差一点的时候完成。(4)制定了Nb - STJ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.
