ATLAS实验正在为计划中的大型强子对撞机(超级发光大型强子对撞机或sLHC)的亮度升级做准备,其跟踪开发方案能够承受比目前探测器更大数量级的辐射通量和更高的命中占用率。这导致了全硅跟踪器的概念,其具有增强的性能、基于像素的内部区域和用于大部分更高半径的短带。这两个子系统采用了许多共同的技术,包括建议的“冷却壁”概念的综合冷却和支持。对于短带区域,使用这种集成冷却壁概念需要将单面模块安装在薄的中央轻质支撑的两侧。每个传感器分为四行23.82mm长的条带;每行内有1280个74.5μm间距的条带。超过100个原型传感器正在由Hamamatsu Photonics(HPK)交付给日本,欧洲和美国。我们目前的第一个20芯片ABCN 25 ASIC混合这些传感器的结果,第一个原型5120条模块内置40 ABCN 25读出ASIC的结果,和ATLAS跟踪器升级五线谱计划正在开发的混合动力车和模块的状态。
The ATLAS experiment is preparing for the planned luminosity upgrade of the LHC (the super-luminous LHC or sLHC) with a programme of development for tracking able to withstand an order of greater magnitude radiation fluence and much greater hit occupancy rates than the current detector. This has led to the concept of an all-silicon tracker with an enhanced performance pixel-based inner region and short-strips for much of the higher radii. Both sub-systems employ many common technologies, including the proposed “stave” concept for integrated cooling and support. For the short-strip region, use of this integrated stave concept requires single-sided modules mounted on either side of a thin central lightweight support. Each sensor is divided into four rows of 23.82mm length strips; within each row, there are 1280 strips of 74.5μm pitch. Well over a hundred prototype sensors are being delivered by Hamamatsu Photonics (HPK) to Japan, Europe and the US. We present results of the first 20 chip ABCN25 ASIC hybrids for these sensors, results of the first prototype 5120 strip module built with 40 ABCN25 read-out ASICs, and the status of the hybrids and modules being developed for the ATLAS tracker upgrade stave programme.
