超导隧道结（STJ）粒子探测器发展中的一个严重问题是难以设计出对核辐射敏感的大面积探测器。这个问题已经通过使用串联连接的微型STJ组件（串联STJ检测器）来解决，该组件被设计用于检测通过用核辐射照射后衬底（蓝宝石）而产生的非热声子。该探测器不仅对电离事件敏感，而且对非电离事件敏感，为核辐射探测提供了一种新的方法。本文介绍了串联STJ探测器的一些特性。
One of the serious problems in the development of particle detectors with superconducting tunnel junctions (STJ) is the difficulty in devising a large area that is sensitive to nuclear radiations. The problem has been solved by using an assembly of micro STJs connected in series (series‐connected STJ detector), which is designed for detecting nonthermal phonons created by irradiating the rear substrate (sapphire) with nuclear radiations. The present detector is sensitive not only to ionizing events but also to nonionizing events, providing us with a new method to detect nuclear radiations. Some features of the series‐connected STJ detector are described in this article.
