摘要环形正负电子对撞机(CEPC)被认为是精确测量希格斯玻色子性质的希格斯工厂。CEPC顶点探测器要求低材料预算、高空间分辨率、快速读出和低功耗。单片有源像素传感器(MAPS)作为一种很有前途的候选技术,已经在CEPC顶点检测器的研发活动中进行了研究。本文介绍了最近开发的MAPS原型使用TowerJazz 180 nm CMOS图像传感器工艺。设计了两种不同的二进制前端电路,以探索适合于与矩阵内稀疏化读出电路组合的紧凑像素的像素内前端结构。为了实现高粒度和快读出速度,实现了一种新的异步数据驱动矩阵读出结构。原型包含128行和64列,具有25 μ m的小像素间距。一个命中像素的地址可以在25 ns内读出。这项工作提出了原型的设计,目前正在测试中。
Abstract The Circular Electron Positron Collider (CEPC) is proposed as a Higgs factory for precision measurement of properties of the Higgs boson. The CEPC vertex detector requires low material budget, high spatial resolution, fast readout and low power consumption. Monolithic Active Pixel Sensor (MAPS), as one of the promising candidate technologies, has been studied within the R&D activities for the CEPC vertex detector. This proceeding introduces recent development of a MAPS prototype using the TowerJazz 180 nm CMOS Image Sensor process. Two different binary front-end circuits have been designed to explore an in-pixel front-end structure suitable for a compact pixel in combination with an in-matrix sparsified readout circuitry. To achieve high granularity together with fast readout speed, a new architecture of asynchronous data-driven matrix readout has been implemented. The prototype contains 128 rows and 64 columns featuring a small pixel pitch of 25 μ m. The address of one hit pixel can be read out in 25 ns. This work presents the design of the prototype, which is currently under test.
