The International Linear Collider (ILC) project is expected to be the next world-wide particle physics facility. Its accelerators will collide electrons on positrons at energies from 250 GeV up to 1 TeV. While the Large Hadron Collider (LHC) at the research centre CERN has discovered the Higgs particle which helps understand the origin of mass, the ILC will be essential in extending these discoveries and making precision measurements on and with these particles, their properties and modes of interaction. The two facilities are highly complementary and are both needed to challenge and feed the most fundamental theories of our physical world. Intensive world-wide efforts are currently pursued toward these objectives. Accelerator and detector design reports have been completed. Experimental detector collaborations have formed. A site has been selected in Japan to host the ILC. With international support, Japan should soon present the first political decisions. Novel calorimeters based on particle flow algorithm techniques and high granularity detectors have gone apace and are still developed. Prototypes were constructed and tested for the ILC experiments. These activities are coordinated by the international CALICE collaboration. Researchers are achieving unprecedented jet energy resolution, actual particle calorimetry tracking and are now adding precise timing information. Canadians have joined CALICE in 2005 and have already contributed to the effort out of proportion to their number. We would like to be able to continue and expand our work on calorimeter prototypes, taking data at test beams as required and performing major physics analysis of the detector responses. We have to establish the full scope of the results and prepare for their integration into the final designs required by the ILC detectors. This entails detailed response to the different types of particles, full calibration, energy and space resolution performances characteristics, as well as full development of algorithms to operate the detectors.

国际直线对撞机（ILC）项目预计将成为下一个世界性的粒子物理设施。它的加速器将使能量从250 GeV到1 TeV的电子与正电子碰撞。虽然欧洲核子研究中心的大型强子对撞机（LHC）已经发现了希格斯粒子，这有助于理解质量的起源，但ILC将在扩展这些发现和对这些粒子及其相互作用的性质和模式进行精确测量方面发挥重要作用。这两个设施是高度互补的，都需要挑战和喂养我们的物理世界的最基本的理论。目前正在全世界加紧努力实现这些目标。加速器和探测器设计报告已经完成。实验探测器合作已经形成。已在日本选定一个地点作为国际法委员会的东道国。在国际社会的支持下，日本应该很快就能做出第一批政治决定。基于粒子流算法技术和高粒度检测器的新型量热仪已经快速发展，并且仍在开发中。为ILC实验构建并测试了原型。这些活动由CALICE国际协作组织协调。研究人员正在实现前所未有的喷射能量分辨率，实际粒子量热跟踪，现在正在添加精确的时间信息。加拿大人于2005年加入了CALICE，并已为这一努力作出了与其人数不成比例的贡献。我们希望能够继续和扩大我们在量热计原型上的工作，根据需要在测试光束上获取数据，并对探测器响应进行主要的物理分析。我们必须确定结果的全部范围，并准备将其整合到ILC探测器所需的最终设计中。这需要对不同类型的粒子作出详细的反应，全面校准，能量和空间分辨率性能特征，以及全面开发操作探测器的算法。
