Abstract: The discovery and measurements of the Cosmic Microwave Background (CMB) radiation have laid the foundation of the current cosmological model, in which the universe is primarily composed of dark energy and dark matter. Higher-precision measurements of the CMB temperature and polarization anisotropies, enabled by installation of larger numbers of superconducting detectors, will unveil more information about the universe. This thesis will present my work in the Advanced Atacama Cosmology Telescope Polarimeter (AdvACT) and the Simons Observatory (SO). Both the AdvACT and SO are located at ~5200m altitude on Cerro Toco in the Atacama Desert in Chile. The AdvACT is the second and final instrument upgrade of the Atacama Cosmology Telescope (ACT), and is one of the most sensitive ground-based instruments for measuring the CMB anisotropies at small angular scales. The total number of detectors that the SO plans to deploy is one magnitude higher than the AdvACT. The major content of this thesis is related to the development, design, integration and test of the multichroic detector arrays of these two instruments.
