Abstract
In a radiation detection device using superconducting tunnel junctions, the increase in electric capacitance and the decrease in electric resistance due to the increase in junction area for improvement of the detection efficiency are largely repressed by the invention. The junctions are connected in series. The number of the series-connected junctions is settled in the range of larger than 0.05 (SC.sub.o /C')0.5 and smaller than 20 (SC.sub.o /C')0.5 or 10SCo/C', whichever is larger, where S is the total area of the junctions, cm.sup.2, C.sub.o is the electric capacitance per unit area of the junctions, F/cm.sup.2, and C' is the electric capacitance connected to the device in parallel so as to transfer and amplify the signals from the device, F.
