This project covers the hardware design of a large-format, wide-field imager for the Large Synoptic Survey Telescope (LSST). The imager is in the critical path for the LSST, and may eventually represent a $20 M expenditure. The project covers the investigation of key hardware issues for the imager mosaic module, and will include the following tasks: definition of detector specifications based upon community-defined science requirements; competition for the supply of sample imager modules; engineering of the focal plane array layout and cool substrate; panel analysis of the module performance and estimated cost; and the letting of a contract for two science-grade sample modules, with lab tests. The design process is critical to the eventual development of the wide-field imager, which will have broad impact to the astronomical community as a critical component of the LSST.

本项目涵盖了大型天气巡天望远镜（LSST）大画幅、宽视场成像仪的硬件设计。成像仪是在LSST的关键路径，并可能最终代表2000万美元的支出。该项目涵盖了对成像仪拼接模块的关键硬件问题的研究，并将包括以下任务：根据社区定义的科学要求定义探测器规格；成像仪模块样品供应的竞争；焦平面阵列布局与冷基板工程；面板分析模块性能及预估成本；并签订了两个科学级样品模块的合同，并进行了实验室测试。设计过程对大视场成像仪的最终发展至关重要，作为LSST的关键组成部分，它将对天文学界产生广泛的影响。
