我们审查ILC顶点探测器的物理要求，这导致硅像素传感器的规格安排为嵌套桶，可能增强端盖探测器，以增强小极角的覆盖范围。我们描述了如何探测器的要求是一个自然的产物，25年的发展CCD为基础的顶点探测器在固定目标和碰撞束实验，最终在307 Mpixel SLD顶点探测器。我们讨论了该技术最近已分支成十几个架构，可能会在ILC工作，其中的主要挑战是增加有效的读出速率约1000倍相比，传统的CCD，同时保留小像素（类似于20 μ m）和低功耗。在SLD中保持气体冷却为低至0.1%X-0的层厚度打开了大门。最后，我们考虑如何最好地管理电磁干扰与束波场和其他射频源在聚束列车。最后，我们提出了一个战略，从目前丰富的R&D计划，以最佳的探测器启动的ILC物理方案。(c)2006 Elsevier B.

We review the physics requirements for the ILC vertex detectors, which lead to the specification of silicon pixel sensors arranged as nested barrels, possibly augmented by endcap detectors for enhanced coverage of small polar angles. We describe how the detector requirements are a natural outgrowth of 25 years development of CCD-based vertex detectors in fixed-target and colliding beam experiments, culminating in the 307 Mpixel SLD vertex detector. We discuss how the technology has recently branched out into about a dozen architectures which might be made to work at the ILC where the main challenge is to increase the effective readout rate by about a factor 1000 compared to conventional CCDs, while preserving the small pixels (similar to 20 mu m) and low-power dissipation. Preserving gaseous cooling as at SLD opens the door to layer thicknesses as low as 0.1% X-0. Finally, we consider how best to manage electromagnetic interference associated with the beam waketields and other RF sources during the bunch train. In conclusion, we suggest a strategy for moving on from the present rich R&D programmes to optimal detectors for the startup of the ILC physics programme. (c) 2006 Elsevier B.V. All rights reserved.
