Experimental high-energy physics is almost entirely carried out by large international collaborations based at a very few facilities located around the world. The University of Toronto is currently involved in two of the most high-profile new experiments in the world, the ATLAS experiment at the CERN Large Hadron Collider, which will study physics at an entirely new energy scale, and the T2K experiment in Japan, which will provide precision measurements in the neutrino sector of the Standard Model. Additionally, we are involved with R&D related to future accelerators, with research on the design, construction and testing of superconducting RF cavities for an electron linear accelerator. The infrastructure needed to maintain both existing and future research efforts is substantial. For instance, the large volumes of data that will be produced by the LHC experiments have lead to a grid computing model in which data will be distributed amongst computer centres around the world. These centres are of different sizes, referred to as Tier-0 (at CERN), Tier-1 (there are 10 around the world, with one located at TRIUMF), Tier-2 and Tier-3. There will be two Tier-2 centres in Canada, with the largest situated mainly at the University of Toronto, as part of the SciNet computing facilities funded through the CFI. The purchase and installation of this facility is now in progress. However, for some years we have had a 500-cpu Linux cluster financed in a previous CFI competition, and since 2004 we have employed an MFA-funded person responsible for managing the scientific use of this cluster, in support of the various experimental groups. This person has played a key role in the design of the SciNet facility, and is expect to continue this level of involvement. Additionally we currently support a High-Energy Physics Engineer, who has played key roles in the group's hardware contributions to both ATLAS and T2K. His expertise will be needed during at least the initial T2K running, and access to his skills also forms an important part of our plans for R&D on ATLAS upgrades and superconducting RF cavities. In addition, reinstating an Instrumentation Technologist position is crucial to the continuation of our work in these fields.

高能物理实验几乎完全是通过位于世界各地的极少数设施的大型国际合作来进行的。多伦多大学目前正在参与世界上最引人注目的两项新实验：欧洲核子研究组织大型强子对撞机的 ATLAS 实验，该实验将在全新的能源尺度上研究物理学，以及日本的 T2K 实验，该实验将在一个全新的能源尺度上研究物理学。将提供标准模型中微子区域的精确测量。此外，我们还参与与未来加速器相关的研发，研究电子直线加速器超导射频腔的设计、构建和测试。维持现有和未来的研究工作所需的基础设施是巨大的。例如，大型强子对撞机实验将产生大量数据，从而形成网格计算模型，其中数据将分布在世界各地的计算机中心之间。这些中心规模各异，分别称为 Tier-0（位于 CERN）、Tier-1（全球共有 10 个中心，其中一个位于 TRUMF）、Tier-2 和 Tier-3。加拿大将有两个二级中心，其中最大的中心主要位于多伦多大学，作为 CFI 资助的 SciNet 计算设施的一部分。该设施的购买和安装正在进行中。然而，多年来我们在之前的 CFI 竞赛中资助了一个 500 个 CPU 的 Linux 集群，并且自 2004 年以来，我们聘请了一位由 MFA 资助的人员负责管理该集群的科学使用，以支持各个实验组。此人在 SciNet 设施的设计中发挥了关键作用，并预计将继续这种程度的参与。此外，我们目前还支持一名高能物理工程师，他在该团队对 ATLAS 和 T2K 的硬件贡献中发挥了关键作用。至少在最初的 T2K 运行期间需要他的专业知识，而利用他的技能也是我们 ATLAS 升级和超导射频腔研发计划的重要组成部分。此外，恢复仪器技术专家职位对于我们继续在这些领域的工作至关重要。
