Argus : a 16-pixel millimeter-wave spectrometer
Abstract/Contents
- Abstract
- This thesis presents the development and deployment of Argus, a 16-pixel millimeter-wave spectrometer for the 100 m Robert C. Byrd Green Bank Telescope (GBT). Argus enables astronomical imaging at state-of-the-art mapping speeds and high angular resolution over the 76-116 GHz band. Its applications include studies of star formation, comets, astrobiology, and astrochemistry. Argus was installed on the GBT and measured rst light in March 2016. It will be available to the general radio astronomy community beginning in the winter 2016 observing semester. This work has demonstrated a novel scalable approach to building a focal plane array. The Argus array is built in 4-pixel subunits, which are tiled together to form the 16-pixel array. In principle, these subunits could be used as the building blocks of an even larger array. Every part is designed to be compact, mass-producible, and as economical as possible. The core technology is based on miniaturized receiver modules, which integrate low-noise ampli ers, a bandpass lter, and a mixer into a single compact unit that would be amenable to automated assembly. The Argus receiver array achieved low noise performance over a very wide bandwidth, which both enables a number of new scienti c opportunities in the near term while demonstrating the viability of the design concept for future receiver designs.
