利用超导隧道结研制硬X射线和α粒子低温探测器的工作已经开始。已经制作了具有系列STJ阵列的探测器芯片，并进行了用于评估芯片性能的实验。对5.48MeV的α粒子获得了0.77%的半峰全宽能量分辨率。相反，硬X射线的能量分辨率一直很差，因为坏的信噪比。
Development of cryogenic detectors for hard X-rays and α-particles using superconducting tunnel junctions has been started. Detector chips with series STJ arrays have been fabricated and experiments for evaluation of the chip properties have been carried out. 0.77% of energy resolution in full-width at half-maximum for 5.48 MeV α-particles has been obtained. To the contrary, energy resolutions for hard X-rays have been poor because of bad signal-to-noise ratio.
