This CAREER award will enable Dr. Kuo and his team to develop technology that will assist in the design of the POLAR array. The POLAR array will be a ground-based array that will detect and characterize the polarization signal in the cosmic microwave background (CMB), one of the most reliable and powerful probes in cosmology. Many cosmological parameters have been determined through the study of this remnant of the Big Bang. The technology development components of the proposal include the design of the focal plane, the detector/feed antenna architecture, readout electronics, techniques to implement large cold optics, and large aperture infrared filtering. All of these have the goal of maximizing the scientific output of the POLAR array.The broader impacts of the award include the training of undergraduate, graduate, and post-doctoral students. Data obtained by the array will serve as a legacy data set on the high-redshift mass distribution which will benefit the entire astronomical community. Dr. Kuo and his team will also work with teachers that take part in a RET program at Stanford.

这项职业奖将使郭博士和他的团队能够开发有助于POLAR阵列设计的技术。POLAR阵列将是一个地面阵列，用于探测和表征宇宙微波背景（CMB）中的极化信号，这是宇宙学中最可靠和最强大的探测器之一。通过对大爆炸遗迹的研究，已经确定了许多宇宙学参数。该提案的技术开发组件包括焦平面设计、探测器/馈电天线架构、读出电子器件、实现大冷光学的技术和大孔径红外滤波。所有这些都是为了最大限度地提高POLAR阵列的科学输出。该奖项更广泛的影响包括培养本科生、研究生和博士后。该阵列获得的数据将作为高红移质量分布的遗留数据集，使整个天文学界受益。郭博士和他的团队还将与参加斯坦福大学RET项目的教师合作。
