布鲁克海文国家实验室STAR实验用高集成度硅探测器的设计和制造
Design and Fabrication of a Highly Integrated Silicon Detector for the STAR Experiment at Brookhaven National Laboratory
摘要：
我们提出了一个探测器的设计，用作粒子跟踪装置在布鲁克海文国家实验室的RHIC对撞机的STAR实验。“板条”，其中24个组成了完整的探测器，是一个高度机械集成的设计，包括6个定制的硅传感器安装在Kapton基板。4608引线键合将这些传感器连接到安装在同一基板上的36个模拟前端芯片。从混合电路到前端芯片的电源和信号连接由引线键合提供。整个电路安装在一个碳纤维基地共固化到Kapton基板。我们提出了这种探测器的独特的设计挑战和克服它们的一些新技术。
英文摘要：
We present the design of a detector used as a particle tracking device in the STAR experiment at the RHIC collider of Brookhaven National Laboratories. The "stave," 24 of which make up the completed detector, is a highly mechanically integrated design comprised of 6 custom silicon sensors mounted on a Kapton substrate. 4608 wire bonds connect these sensors to 36 analog front-end chips which are mounted on the same substrate. Power and signal connectivity from the hybrid to the front-end chips is provided by wire bonds. The entire circuit is mounted on a carbon fiber base co-cured to the Kapton substrate. We present the unique design challenges for this detector and some novel techniques for overcoming them.
