AI 中文摘要
ALICE合作组计划在LHC的长期停机4期间进行ALICE~3升级，制造一个基于65纳米生产节点的硅MAPS技术的全新跟踪探测器。整个有源区计划为50平方米，外跟踪器占45平方米。为达到每层材料预算目标低于1% $X_0$，冷却解决方案、机械结构和电子学等问题待解决。开发了简单的传感器原型MADHAT，与最终传感器机械相同，但集成了加热元件和温度探头，用于研究最终探测器组件中的温度分布、评估容纳传感器的电路板的不同机械设计，还将用于实践整个大规模生产的工业化，包括与外部公司组装FPC。本文展示了MADHAT的设计、原型读出模块及首次测量结果。
英文摘要
The ALICE collaboration plans a completely new tracking detector based on silicon MAPS technology manufactured in the 65 nm production node as part of the ALICE~3 upgrade during Long Shutdown 4 of the LHC. The size of the whole active area is planned to be 50 m$^2$, with the Outer Tracker spanning 45 m$^2$. To reach the material budget target of less than 1% $X_0$ per layer, open questions like cooling solutions, mechanical structures and electronics have to be answered. A simple sensor prototype MADHAT (Mechanical Assessment Design for Heat And Thermal solutions), mechanically identical to the final sensor, but with integrated heating elements and temperature probes, was developed to study the temperature distribution in the final detector assembly and to assess different mechanical designs of the circuit board that houses the sensor. Furthermore, it will be used to practice the industrialization of the whole mass-production, including the assembly of FPCs with external companies. In this paper, we present the design of the MADHAT, a prototype readout module and show the results of first measurements.
