This is a proposal to PPARC for a 3 year R&D programme aimed at answering key questions associated with the design of a replacement tracker for the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. In order to increase further the ability of the LHC to discover and study fundamental physics at the smallest scales, it is proposed to extend LHC running and to greatly increase the collision rate after a long shutdown starting in 2014. To maintain the performance of ATLAS in this new phase of data-taking it will be necessary to replace the central component of the experiment which tracks the trajectories of charged particles produced in LHC collisions. This new 'tracker' will require novel technologies in order to withstand the much increased radiation flux associated with the greater collision rate and yet still measure the much larger numbers of charged particles per unit time with the same precision as will be obtained prior to the LHC upgrade. This project will develop these technologies and incorporate them into a layout for the replacement tracker which meets all the requirements imposed by physics performance, radiation tolerance and other constraints.

这是PPARC的一项为期3年的研发计划，旨在回答与欧洲核子研究中心大型强子对撞机（LHC）ATLAS实验替代跟踪器设计相关的关键问题。为了进一步提高LHC在最小尺度上发现和研究基础物理的能力，建议延长LHC的运行时间，并在2014年开始长时间关闭后大幅提高碰撞率。为了保持ATLAS在这一新的数据采集阶段的性能，有必要更换实验的核心部件，该部件跟踪LHC碰撞中产生的带电粒子的轨迹。这种新的“跟踪器”将需要新的技术，以承受与更大的碰撞率相关的更大的辐射通量，但仍然测量单位时间内更大数量的带电粒子，其精度与LHC升级之前相同。该项目将开发这些技术，并将其纳入替代跟踪器的布局中，以满足物理性能、辐射容限和其他限制所提出的所有要求。
