CALICE SiW ECAL --板上芯片PCB解决方案的开发和测试

CALICE SiW ECAL -- Development and test of the chip-on-board PCB solution

Adrian Irles

摘要:

高颗粒硅钨电磁量能器(SiW ECAL)是国际大型探测器(ILD)概念的ECAL参考设计,这是未来国际直线对撞机(ILC)提出的两个探测器概念之一。这种类型的探测器的原型是在CALICE协作范围内开发的。这篇文章报道了一种超薄PCB的发展,称为板上芯片(COB),配备了引线键合ASIC和像素化硅晶片。这一组将构成SiW ECAL检测的基本单元。这将有利于超紧凑型热量计的设计,因为这些板的厚度为1.2 mm,与BGA封装中使用ASIC的默认解决方案变体的3 mm相比。我们还报告的第一个结果与COB板上的梁测试在DESY。

英文摘要:

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.
