论文摘要
高度颗粒状的硅 - 丁香电磁热量计（SIW ECAL）是国际大型探测器（ILD）概念的ECAL的参考设计，这是为未来国际线性碰撞者（ILC）提出的两个检测器概念之一。这种类型的检测器的原型是在Calice协作中开发的。这项贡献报告了一种称为Chip-on-Board（COB）的超薄PCB的开发，该PCB配备有线轴的ASIC和像素化硅晶片。该集合将构成SIW ECAL检测的基本单位。它将有利于超紧凑量热量表的设计，因为这些板的厚度为1.2 mm，可与使用BGA包装中ASIC的3毫米默认解决方案变体进行比较。我们还报告了DESY的横梁测试中使用芯片板获得的第一个结果。
The highly granular silicon-tungsten electromagnetic calorimeter (SiW ECAL) is the reference design of the ECAL for the International Large Detector (ILD) concept, one of the two detector concepts proposed for the future International Linear Collider (ILC). Prototypes for this type of detector are developed within the CALICE Collaboration. This contribution reports on the development of an ultra-thin PCB called Chip-on-Board (COB) that is equipped with wirebonded ASICs and pixelated silicon wafers. This set will form the basic unit of detection of the SiW ECAL. It will favour the design of an ultra compact calorimeter since these boards feature a thickness of 1.2 mm to be compared with the 3 mm of the default solution variant using ASICs in BGA packaging. We report also on the first results obtained with the COB boards on a beam test at DESY.
