The Collider Detector at Fermilab (CDF) experiment is enabling the study of the highest energy proton-antiproton collisions at a centre-of-mass energy near 2 TeV. The CDF collaboration consists of scientists from 15 countries, including a group of Canadian physicists affiliated with the Institute of Particle Physics (IPP). The IPP group joined CDF in 1991 for the Run I datataking period, which had as its highlight the discovery of the top quark. In Run II, performance of the Fermilab Tevatron collider and CDF apparatus have been high with peak luminosities in excess of 3E32/cm^2/s and data-taking efficiencies near 90%, enabling us to collect and process over 4/fb of data to date. The current Tevatron run is envisaged to end in 2010, with a projected integrated luminosity nearly twice that processed so far. The IPP-Canada group is currently leading or engaged in studies of b-jet production, b-hadron fragmentation, single-top-quark production, searches for exotic W' and Z' bosons, precision measurements of the W boson mass, the search for the low-mass Standard Model Higgs boson, and exclusive final states from photo-produced quarkonia or two-photon QED interactions. Results from topics in this broad range are both unique and complementary to what can be achieved using the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. With the current commissioning of the LHC, overall Canadian involvement in CDF has been ramping down as scientific resources have naturally been redirected to the large Canadian ATLAS effort. The present proposal is for operating support of groups at four Canadian institutions consisting of researchers that joined the Canadian CDF II effort more recently (in 2003 and 2008) and are therefore well positioned to complete the capitalization of NSERC's investment in the CDF II experiment and its physics in a manner that is complementary to the intensifying LHC effort. This will allow our graduate students and researchers to meet their service obligations to CDF up to the termination of data taking and to complete several legacy physics analyses at a time when some of the most exciting physics in the history of the Tevatron program will be explored.

Fermilab（CDF）实验的对撞机检测器正在实现在2 TEV附近的质量中心能量中最高能量质子 - 抗球菌碰撞的研究。 CDF合作由来自15个国家的科学家组成，其中包括隶属于粒子物理研究所（IPP）的一组加拿大物理学家。 IPP组在1991年加入了CDF，在运行I DataTaking期间，它突出了最高Quark的发现。在Run II中，Fermilab Tevatron对撞机和CDF设备的性能较高，峰值发光度超过3E32/cm^2/s，并且在90％附近的数据提取效率，使我们能够收集和处理超过4/FB数据的数据。当前的Tevatron Run设想将于2010年结束，预计的集成光度几乎两次处理。 The IPP-Canada group is currently leading or engaged in studies of b-jet production, b-hadron fragmentation, single-top-quark production, searches for exotic W' and Z' bosons, precision measurements of the W boson mass, the search for the low-mass Standard Model Higgs boson, and exclusive final states from photo-produced quarkonia or two-photon QED interactions.在这个广泛范围内的主题的结果既独特又是互补的，并且使用CERN的大型强子对撞机（LHC）的Atlas实验可以实现的目标。 随着LHC目前的调试，由于科学资源自然被重定向到加拿大大型Atlas的努力，加拿大参与CDF的总体参与一直在逐渐下降。目前的提案是为了在加拿大四个机构的集团的运营支持，这些研究人员最近加入了加拿大CDF II的工作（2003年和2008年），因此在CDF II实验及其物理学中的资本化良好，以对强化LHC的努力进行互补的方式完成了资本化。这将使我们的研究生和研究人员能够履行其服务义务，以终止数据获取，并在探索Tevatron计划历史上一些最令人兴奋的物理学的时候完成了一些旧的物理分析。
