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.

这是针对PPARC进行3年研发计划的一项建议，旨在回答与CERN大型强子撞机（LHC）ATLAS实验的替换跟踪器有关的关键问题。 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.这种新的“跟踪器”将需要新型技术，以承受与更高的碰撞速率相关的大大增加的辐射通量，但仍以与LHC升级之前获得的精度相同的精度，但仍在测量大量的电荷颗粒。该项目将开发这些技术，并将它们纳入替换跟踪器的布局中，该替换跟踪器满足物理性能，辐射公差和其他约束所施加的所有要求。
