The Cosmic Microwave Background has become one of our fundamental tools for understanding the global properties of the universe. It has already yielded high-precision cosmological results, with the promise of even more to come. The brute force CMB analysis methods are computationally prohibitive for all but the simplest experiments, so we have developed new analysis methods for use on interferometric microwave background data. We apply these methods to the data from the Cosmic Background Imager (CBI) to obtain a power spectrum, and, both alone and in concert with other experiments, use the power spectrum to measure fundamental cosmological parameters. The CBI is a very sensitive 13-element interferometer located at 16,700 feet in northern Chile that has provided the highest resolution measurements yet of primary CMB anisotropies.
