This project looks to build a new instrument for the Fred Young Submillimeter Telescope (FYST) in Chile that is part of the CCAT-prime project. The instrument being developed will be installed on FYST to measure light at a wavelength of 0.9 millimeters (350 GHz). The measurements will help astronomers learn about properties of dust and magnetic fields in the Milky Way galaxy. Understanding the Milky Way better will help researchers remove those signals from the foreground to study more distant light from the early Universe. Combining these results with other data will help understand the evolution of the Universe soon after the Big Bang. New research opportunities for students from underrepresented backgrounds and from community colleges are planned.The new instrument for FYST will enable 350 GHz polarization measurements with the CCAT-prime project. It will be within an instrument module that includes three arrays of kinetic inductance detectors (KIDs) and will provide the first polarization-sensitive measurements to exceed the current best 350 GHz data from the Planck satellite mission. This will be one of the largest scale deployments of KIDs yet, which will help advance this important technology for future applications. The instrument module will be deployed in the Prime-Cam receiver cryostat on the six-meter aperture FYST at an elevation of 18,400 feet on Cerro Chajnantor in Chile. Improved 350 GHz polarization measurements are important for advancing our understanding of Galactic dust parameters, magnetic field properties, and molecular clouds where star formation occurs. Uncertainties in these Galactic foreground sources limit constraints on the amplitude of primordial gravitational waves. Improving measurements of galactic foregrounds has the potential to reduce bias in future constraints on early Universe inflation. Developing and deploying the proposed instrumentation in a first light receiver for the CCAT-prime project will provide opportunities for training young researchers and lead to exciting astrophysical measurements from one of the best sub-millimeter sites on earth.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.

该项目旨在为智利的弗雷德·杨亚毫米望远镜(FYST)建造一台新仪器，这是CCAT-PRIME项目的一部分。正在开发的仪器将安装在FYST上，以测量0.9毫米(350 GHz)波长的光。这些测量将帮助天文学家了解银河系中尘埃和磁场的特性。更好地了解银河系将有助于研究人员从前景中移除这些信号，以研究来自早期宇宙的更远的光。将这些结果与其他数据结合起来，将有助于理解宇宙在大爆炸后不久的演化。来自代表性不足的背景和社区大学的学生计划有新的研究机会。FYST的新仪器将通过CCAT-PRIME项目实现350 GHz偏振测量。它将在一个包括三个动态电感探测器(KIDS)阵列的仪表舱内，并将提供第一批偏振敏感测量，以超过目前来自普朗克卫星任务的最佳350 GHz数据。这将是迄今为止规模最大的儿童部署之一，这将有助于推动这项重要技术在未来的应用中发挥作用。该仪器模块将部署在智利Cerro Chajnantor上海拔18400英尺的6米口径FYST上的Prime-Cam接收器低温恒温器中。改进的350 GHz偏振测量对于促进我们对银河系尘埃参数、磁场性质和恒星形成所在的分子云的理解非常重要。这些银河系前景源的不确定性限制了对原始引力波幅度的限制。改进对银河系前景的测量有可能减少未来对早期宇宙膨胀的限制。在CCAT-PRIME项目的第一个光接收器中开发和部署建议的仪器将为培训年轻研究人员提供机会，并导致在地球上最好的亚毫米站点之一进行令人兴奋的天体物理测量。该奖项反映了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。
