APPLYING DETECTOR ADVANCES TO THE LSST CAMERA

本项目主要是为大型综合巡天望远镜（LSST）设计一台大幅面、宽视场成像仪。成像仪处于LSST的关键路径中，并且最终可能代表2000万美元的支出。该项目包括调查成像器镶嵌模块的关键硬件问题，并将包括下列任务：根据共同体确定的科学要求确定探测器规格;竞争供应成像器模块样品;焦平面阵列布局和冷却基片的工程设计;模块性能和估计成本的小组分析;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。设计过程对于最终开发宽视场成像仪至关重要，而宽视场成像仪作为LSST的一个关键组成部分，将对天文学界产生广泛影响。

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.
