The CERN Large Hadron Collider (LHC) will have the highest direct energy reach of any particle physics facility for decades, and Canada's central role in the ATLAS collaboration at the LHC will keep us in the forefront of international particle physics. ATLAS has already announced the discovery of a new particle consistent with the Standard Model Higgs boson, opening the door to a new era in our understanding or the origin of mass and matter. While the LHC and ATLAS will only complete our first extended physics operational period this year, we are already entering the construction era for upgrading both the LHC accelerator and the ATLAS detector sub-systems. In order to extend the reach of the LHC physics program, it is intended to increase the instantaneous luminosity of the collider. The increase in instantaneous luminosity will require significant detector upgrades using technologies capable of handling the higher rates and radiation doses. This request is for funds for Canadian physicists to design, build and install essential upgrades for the first phase of ATLAS upgrades, and to complete R&D necessary for longer term improvements.

数十年来，CERN大型强子对撞机（LHC）将拥有任何粒子物理设施的最高直接能量覆盖范围，而加拿大在LHC的Atlas合作中的核心作用将使我们处于国际粒子物理学的最前沿。阿特拉斯（Atlas）已经宣布发现了与标准模型希格斯玻色子（Higgs Boson）一致的新粒子，这为我们的理解或质量和物质起源打开了大门。尽管LHC和ATLAS只能完成我们今年的第一个扩展物理运营期，但我们已经进入了升级LHC加速器和Atlas检测器子系统的施工时代。为了扩展LHC物理计划的范围，它旨在增加对撞机的瞬时光度。瞬时发光度的增加将需要使用能够处理较高速率和辐射剂量的技术进行大量检测器升级。此请求是为加拿大物理学家提供资金，以设计，建立和安装Atlas升级的第一阶段的基本升级，并完成长期改进所需的研发。
