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.

CERN大型强子对撞机(LHC)将拥有几十年来任何粒子物理设施中最高的直接能量覆盖范围，加拿大在LHC的ATLAS合作中的核心作用将使我们保持在国际粒子物理的前沿。阿特拉斯已经宣布发现了一种与标准模型希格斯玻色子一致的新粒子，打开了我们理解质量和物质起源的新纪元的大门。虽然大型强子对撞机和ATLAS将在今年完成我们的第一个延长的物理运行期，但我们已经进入了升级大型强子对撞机加速器和ATLAS探测器子系统的建造阶段。为了扩大大型强子对撞机物理计划的范围，它打算增加对撞机的瞬时光度。瞬时光度的增加将需要使用能够处理更高的辐射速率和辐射剂量的技术来大幅升级探测器。这项请求是为加拿大物理学家提供资金，以设计、建造和安装ATLAS升级的第一阶段所需的基本升级，并完成长期改进所需的研发。
