Scientific paper

The theory of the Cosmic Microwave Background (CMB) is presented, and the ability of CMB anisotropy measurements to test cosmological models, including Dark Matter models and galaxy formation scenarios, is discussed. Experimental techniques used in measuring CMB anisotropy are described, including the design and fabrication of a new receiver for the Millimeter-wave Anisotropy Experiment (MAX), based on an Adiabatic Demagnetization Refrigerator (ADR). The results of the first three flights of the MAX experiment are reviewed, and a detailed description of the data from the fourth flight of MAX using the new ADR-based receiver is presented. Data analysis and noise reduction methods are described, and potential systematic errors and foreground sources effecting the experiment are addressed. the cumulative measurements of CMB anisotropy by the MAX experiment are summarized, and comparisons are made to other measurements of CMB anisotropy on both medium and large angular scales.
