使用小口径、大规模生产的望远镜进行大视场测量有可能将仪器硬件成本降低几个数量级。Argus阵列系列仪器将通过高节奏、全天空成像为光学瞬变研究开辟新途径。第一个原型，九望远镜阿格斯技术演示器，已经在天空中，并验证了跟踪和高速数据简化的新概念。接下来，资金充足的Argus Pathfinder由38台望远镜组成，将在每晚观测-20°至+72°的天空。该项目计划以Argus光学阵列的形式达到高潮，该阵列将以1秒的速度用900台望远镜同时观测整个天空的20%。随着望远镜数量的增加，维护要求也在增加。对于一个标准的露天阵列在许多安装，这可能会导致运营成本远远超过那些等效的单片望远镜，并导致不一致的天空覆盖，而部分阵列离线。为了减少磨损以及清洁、重新校准和调焦的需要，我们将望远镜密封在过滤和空调环境中。这个外壳将被严格绝缘，并保持在一个足够小的温度范围内，以防止望远镜焦点发生可测量的变化。存储模块中的摄像机和其他电源采用水冷方式，热量会被转移到包含阵列的HVAC和支持设备的隔离服务模块。从那里，系统温度保持在几个季节性变化的设定点。本文介绍了探路者的外壳和环境控制系统的设计。
Wide-field surveys using small-aperture, mass-produced telescopes have the potential to lower instrument hardware costs by orders of magnitude. The Argus Array series of instruments will open new pathways into the study of optical transients via high-cadence, all-sky imaging. The first prototype, the nine-telescope Argus Technology Demonstrator, is already onsky and validates novel concepts in tracking and high-speed data reduction. Next, the fully funded Argus Pathfinder consists of 38 telescopes on a single mount, and will observe the sky between -20° and +72° declination over the course of each night. The project is planned to culminate with the Argus Optical Array observing 20% of the entire sky simultaneously with 900 telescopes at cadences as fast as 1 second. As the number of telescopes increases, so do the maintenance requirements. For a standard open-air array on many mounts, this could result in operations costs far in excess of those of an equivalent monolithic telescope and lead to inconsistent sky coverage while parts of the array are offline. To limit wear and the need for cleaning, re-alignment and focusing, we seal our telescopes in a filtered and air-conditioned environment. This enclosure will be heavily insulated and maintained within a temperature range small enough to prevent measurable changes in telescope focus. Cameras and other power sources in the enclosure are water-cooled and the heat is removed to an isolated service module containing the array’s HVAC and support equipment. From there, the system temperature is maintained at a few seasonally changed set-points. This paper presents the design of the Pathfinder enclosure and environmental control system.
