暗能量巡天 CCD 成像仪在费米国家加速器实验室建造，并运送到智利的托洛洛山美洲天文台，安装在 Blanco 4m 望远镜上。描述了与运输仪器的准备、设计用于最小化传输到相机的运输负载的运输箱的开发和测试以及到达天文台后对成像仪的检查有关的几项努力。运输负载被监测并被描述。为了将成像仪安装在望远镜的主焦点处，与之前安装的光学校正器配合，开发了专门的工具来安全地提升、支撑和定位容器。安装和拆卸过程在 FNAL 的望远镜模拟器模型上进行了测试，从而最大限度地降低了 CTIO 所执行工作的技术和进度风险。成像仪的最终安装计划于 2012 年 8 月进行。
The Dark Energy Survey CCD imager was constructed at the Fermi National Accelerator Laboratory and delivered to the Cerro Tololo Inter-American Observatory in Chile for installation onto the Blanco 4m telescope. Several efforts are described relating to preparation of the instrument for transport, development and testing of a shipping crate designed to minimize transportation loads transmitted to the camera, and inspection of the imager upon arrival at the observatory. Transportation loads were monitored and are described. For installation of the imager at the telescope prime focus, where it mates with its previously-installed optical corrector, specialized tooling was developed to safely lift, support, and position the vessel. The installation and removal processes were tested on the Telescope Simulator mockup at FNAL, thus minimizing technical and schedule risk for the work performed at CTIO. Final installation of the imager is scheduled for August 2012.
