Title: 韩国ALICE小组在下一代硅探测器的开发和生产方面的活动

Abstract: ALICE 3 is the proposed next-generation heavy-ion experiment at the CERN Large Hadron Collider (LHC), envisioned for operation during Run 5. The tracking system of ALICE 3 will consist of a high-precision vertex detector integrated into a retractable structure inside the beam pipe, complemented by a large-area outer tracker covering a broad pseudorapidity range. Both systems will be based on the Monolithic Active Pixel Sensor (MAPS) technology, building upon the developments realized for the recently upgraded ALICE Inner Tracking System (ITS2) and the future ITS3 upgrade. The total silicon area of the ALICE 3 tracking system is expected to be approximately five times larger than that of ITS2, presenting significant challenges in terms of large-scale sensor testing and module production. To address these challenges, research and development activities have been initiated in Korea, including the adaptation of an automated die-attach machine, commonly used in the semiconductor packaging industry, for efficient sensor-to-substrate assembly. This contribution presents the ongoing efforts of the Korea ALICE group toward the development and production of the ALICE 3 silicon tracker. The scope includes sensor evaluation, automated assembly techniques, and prototype module construction, with the aim of establishing scalable procedures for future mass production.

Abstract: ALICE 3 是在 CERN 大型强子对撞机（LHC）上提出的下一代重离子实验，计划在 Run 5 期间运行。ALICE 3 的跟踪系统将由一个高精度顶点探测器组成，该探测器集成在束流管道内的可伸缩结构中，并由一个大面积外跟踪器补充，覆盖广泛的伪快度范围。这两个系统都将基于单片有源像素传感器（MAPS）技术，建立在最近升级的 ALICE 内部跟踪系统（ITS2）和未来 ITS3 升级所实现的发展基础上。ALICE 3 跟踪系统的总硅面积预计将是 ITS2 的五倍左右，在大规模传感器测试和模块生产方面带来了重大挑战。为应对这些挑战，韩国已启动了相关研究和开发活动，包括将常用于半导体封装行业的自动芯片粘接机适配用于高效的传感器到基板组装。本贡献介绍了韩国 ALICE 小组在 ALICE 3 硅跟踪器的开发和生产方面的持续努力。其范围包括传感器评估、自动化组装技术以及原型模块的构建，旨在为未来的批量生产建立可扩展的流程。
