APPLYING DETECTOR ADVANCES TO THE LSST CAMERA

本项目是大型天文观测望远镜(LSST)大幅面、广视场成像仪的硬件设计。成像仪处于LSST的关键路径，最终可能代表着2000万美元的支出。该项目包括调查成像仪拼接模块的主要硬件问题，并将包括以下任务：根据社区确定的科学要求确定探测器规格；竞争样品成像仪模块的供应；设计焦平面阵列布局和冷衬底；对模块性能和估计成本进行小组分析；签订两个科学级样品模块的合同，并进行实验室测试。设计过程对广域成像仪的最终开发至关重要，作为LSST的关键组成部分，它将对天文学产生广泛的影响。

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.
