The laser-wire activities in Oxford aim at demonstrating that it is possible to measure the size of the ILC beams with a resolution of 1 micrometre or less by using a laser beam scanned accross the path of the electrons. To achieve such goals tests will be done at the Accelerator Test Facility (ATF) at KEK in Japan and at PETRA, DESY in Germany. As the ILC will need beam size measurements in several different locations, it is important to demonstrate that many laser-wire can be coordinated to work sequentially at the same facility. Such scheme will also be tested in Japan. At the ILC bunches of particles within a train will be spaced only by hundreds of nanoseconds but trains containing thousands of bunches will be spaced by almost two hundreds milliseconds. This makes the requirements on the laser very specific and no such laser exists to date but we plan to build one. This high power laser will also have to be more stable and reliable than what is currently available. Leading the effort to build a laser suitable for the ILC will also allow us to offer our expertise to ther groups that might need such lasers such as the group in charge of measurement the beam size at the focus point of the ATF-2. Finally, we will also try to understand how laser-wires can be integrated in the ILC design and how they can help the tuning of the accelerator.

牛津的激光 - 线活性旨在证明可以通过使用激光束扫描的电子路径来测量以1毫米或更少的分辨率测量ILC梁的大小。为了实现此类目标测试，将在日本Kek的加速器测试设施（ATF）和德国Desy的Petra进行。由于ILC需要在几个不同位置进行光束尺寸测量值，因此必须证明许多激光线可以在同一设施上依次工作。这种计划也将在日本进行测试。在ILC，火车内的一堆颗粒只有数百纳秒的间隔，但是包含数千束的火车将被近200毫秒所隔开。这使得激光的要求非常具体，迄今为止没有这样的激光器，但我们计划构建一个激光。这种高功率激光器还必须比当前可用的更稳定和可靠。领导构建适合ILC的激光器的努力还将使我们能够为可能需要这样的激光器（例如负责测量测量的小组）的专业知识提供专业知识，该小组处于ATF-2的焦点。最后，我们还将尝试了解如何将激光 - 线整合到ILC设计中，以及它们如何帮助加速器的调整。
