This project is for the development and construction of a stable, cooled sapphire oscillator that will allow improvements in millimeter wave Very Long Baseline Interferometry by providing an improved frequency reference. Enabling Very Long Baseline Interferometry at higher frequencies would provide for greater angular resolution, which in turn would provide for observations of unprecedented detail of various important science targets, including the center of the Milky Way Galaxy. The technology can be deployed at worldwide sites used for Very Long Baseline Interferometry, and could be deployed at future large millimeter wave telescopes, including the Atacama Large Millimeter Array.

该项目旨在开发和建造一种稳定的冷却蓝宝石振荡器，通过提供改进的频率基准，改进毫米波甚长基线干涉测量。在更高的频率下实现甚长基线干涉测量将提供更高的角分辨率，这反过来将提供对各种重要科学目标（包括银河系中心）前所未有的细节的观测。该技术可以部署在用于甚长基线干涉测量的全球站点上，也可以部署在未来的大型毫米波望远镜上，包括阿塔卡马大型毫米波阵列。
