Equipment: MRI: Track 1 Development of CODAS: A System for Concurrent and Multi-Technique Observations of Time-Sensitive Stellar Astrophysics

近几十年来，天文学家发现，宇宙在所有时间尺度上都比之前认为的更具活力。依赖于同时使用多台仪器进行观测的天文研究在组织和实现方面具有挑战性。并发观测和数据采集系统(CODAS)提供了一个多模式的观测工具，可以满足对同步数据的需求。这个项目将把现有的和新的硬件集成到一个单一的、有凝聚力的仪器中，可以探索时间敏感的天体物理学的许多领域。眼镜蛇仪器阵列在从紫外线到红外的广泛波长范围内都很灵敏。用户将能够为他们的观测快速选择最优的仪器配置。来自附近拉美裔服务机构的学生将被招募，并在他们的年度实习计划中优先考虑。CODAS利用指向平台的能力来携带共同对准的36英寸和14英寸望远镜以及导航获取包(GAP)，该包可将光线快速重定向到36英寸上的多个仪器访问端口之一。该项目将设计、设计和记录支持并行数据采集(同时36英寸和14英寸观测)和连续数据采集(36英寸间隙上的不同仪器端口)所需的硬件和软件。它将开发天文学家使用尾巴进行有效观测所需的用户软件界面。现有的观测模式有标准滤光光度法、长缝和梯形光谱仪，以及高精度的偏振仪，其中包括高效率的成像偏振仪。大多数仪器的设计都是为了在近紫外线(300 Nm)到近红外(1000 Nm)的大气截止范围内敏感，并利用天文台典型的亚弧秒观测。额外的近红外探测器将成像和光谱模式的范围扩大到2.5微米。这项工作增加了使用多个仪器响应时间域关键瞬变事件的关键能力。该项目将在仪器设计、工程和制造以及软件开发领域为高中和大学阶段的实习生提供培训。这一奖项致力于/推进宇宙之窗的目标。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

In recent decades, astronomers have discovered that the Universe is more dynamic, on all time scales, than previously believed. Astronomical research that depends on observations made with multiple instruments at the same time is challenging to organize and achieve. The Concurrent Observing and Data Acquisition System (CODAS) offers a multi-mode, observing tool that can address the need for simultaneous data. This project will integrate current and new hardware into a single, cohesive instrument that can explore many areas of time-sensitive astrophysics. The CODAS array of instruments is sensitive over a broad range of wavelengths, from the ultraviolet to the infrared. Users will be able to quickly select the optimal instrument configuration for their observations. Students from nearby Hispanic Serving Institutions will be recruited and prioritized within their annual internship program.CODAS utilizes the capacity of the pointing platform to carry the co-aligned 36-inch and 14-inch telescopes and the Guidance-Acquisition Package (GAP), which quickly redirects light to one of multiple instrument access ports on the 36-inch. This project will design, engineer, and document the hardware and software necessary to support concurrent data acquisition (simultaneous 36-inch and 14-inch observations) and contiguous data acquisition (different instrument ports on the 36-inch GAP). It will develop the user software interface required for astronomers to efficiently observe with CODAS. The available observing modes include standard filter photometry with CCD and CMOS detectors, long-slit and echelle spectrographs, and high-precision polarimeters, including a high-efficiency imaging polarimeter. Most instruments are designed to be sensitive from the atmospheric cutoff in the near-ultraviolet (300nm) to the near-IR (1000nm), and to take advantage of the typical sub-arcsecond seeing at the observatory. Additional near-IR detectors extend this range to 2.5 microns for the imaging and spectroscopic modes. This work adds a crucial ability to respond to time domain-critical transient events with multiple instruments. This project will provide training for high school and early college-level interns in the areas of instrument design, engineering and fabrication, and software development. This award addresses/advances the goals of the Windows on the Universe Big Idea.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
