This award supports work performed by the National Radio Astronomy Observatory (NRAO) on the Atacama Large Millimeter/submillimeter Array (ALMA) under a contract to the National Astronomical Observatory of Japan (NAOJ). The NAOJ desires NRAO to design and produce sensitive detector components for ALMA. ALMA enables transformational research into the physics of the cold Universe, regions that are optically dark but shine brightly in the millimeter/submillimeter portion of the electromagnetic spectrum. Within the broad range of science accessible with ALMA, the top-level objectives include imaging the redshifted dust continuum and molecular line emission from evolving galaxies as early as a redshift of z~10 (500 million years after the Big Bang), determining the chemical composition and dynamics of star-forming gas in normal galaxies like the Milky Way but at z~3 (75% of the way across the Universe), and measuring the gas kinematics in young disks in nearby star-forming clouds. ALMA has already demonstrated its revolutionary impact with its dramatic images of planet, star and galaxy formation. These results will accelerate as the full array becomes operational, and with the longest baselines ALMA will achieve an angular resolution of tens of milli-arseconds. ALMA provides one to two orders-of-magnitude improvement over previous facilities in all areas of millimeter- and submillimeter-wave observations, including sensitivity, angular resolution and image fidelity.NRAO will design and produce ALMA Band 1 (35-50 GHz) low noise amplifiers and associated test and support equipment. The specific details regarding performance, materials, schedules, and other conditions are subject to the provisions of the Statements of Work and contracts between AUI/NRAO and NAOJ.

该奖项支持由国家射电天文台（NRAO）对Atacama大毫米/亚毫米阵列（ALMA）进行的工作，该工作符合日本国家天文台（NAOJ）的合同。 NAOJ希望NRAO设计和生成Alma敏感的探测器成分。阿尔玛（Alma）可以转化为冷宇宙物理学的转化研究，这些区域是光学黑暗但在电磁谱的毫米/亚毫米表中明亮地发光的区域。在与阿尔玛（Alma）可访问的广泛科学范围内，顶级目标包括成像，最早在Z〜10的红移（在大爆炸后5亿年（大爆炸之后的5亿年）中，从不断发展的星系中进行红色缩短的尘埃和分子线排放，确定了Z 〜3（75％）的恒星气体的化学成分和动态，以确定恒星形成气体的动态，并确定75％（75％）（75％）。附近恒星形成云的年轻磁盘的运动学。阿尔玛（Alma）已经用其戏剧性的星球，星星和银河系形成表现出了革命性的影响。这些结果将随着完整阵列的运行而加速，并且使用最长的基准ALMA将获得数十毫秒的角度分辨率。 ALMA在毫米和亚毫米波观测的所有区域中提供了比以前的设施相比，提供一到两个魔力级，包括灵敏度，角度分辨率和图像保真度。NRAO将设计并生产ALMA频段1（35-50 GHz）（35-50 GHz）低噪声放大器以及相关的测试和支持设备。有关绩效，材料，时间表和其他条件的具体细节遵守AUI/NRAO和NAOJ之间的工作声明和合同的规定。
