为欧洲核子研究中心雅典娜实验设计、研制和制造了一种工作在液氮温度下的新型反氢湮没最终产物探测器。需要满足的要求是在高磁场(4T)下低温工作(80K)、体积紧凑、低功耗(5W)和高粒度。探测器由两层组成，每层16个双面硅微带模块(长16厘米)，周围环绕192个纯CsI闪烁晶体(≈4 cm~3)，由雪崩光电二极管读取。前端电子也工作在80K，采用VLSI CMOS工艺实现，并具有自触发功能。
A new kind of detector for the end products of antihydrogen annihilations, operating at liquid nitrogen temperatures, was designed, developed and built for the ATHENA experiment at CERN. Requirements to be met were low-temperature operation (80 K ) in a high magnetic field (4 T ) , compact size, low-power consumption (5 W ) and high granularity. The detector consists of two layers of each 16 double-sided silicon micro-strip modules (16 cm long), surrounded by 192 pure-CsI scintillation crystals (≈4 cm3), read by avalanche photo diodes. The frontend electronic also working at 80 K is realised in VLSI CMOS technology and features a self-triggering capability.
