摘要

到2026年，在HL-LHC的升级过程中，ATLAS跟踪系统将被由像素和条带组成的全硅内部跟踪器(ITk)所取代。ITk像素系统的读出在数据速率方面将是最具挑战性的。读出概念的第一次测试是用ITk像素演示器进行的，该系统由几个ITk风格的模块组成，总共有120个读出芯片。它们的读出是通过GBTx芯片将数据光学传输到atca板作为检测器外组件实现的数据聚合。

ATLAS Phase-II-Upgrade Pixel Demonstrator Read-out

The ATLAS tracking system will be replaced by the all-silicon inner-tracker (ITk) consisting of pixels and strips in the course of the HL-LHC upgrade until 2026. The readout of the ITk pixel system will be most challenging in terms of data rate. First test of readout concepts are performed with the ITk Pixel Demonstrator, a system composed of several ITk-style modules with in total 120 readout chips. Their readout is realised with data aggregation via GBTx chips transmitting data optically to ATCA-boards acting as off-detector components.
