| Outline of Final Research Achievements |
This research aims to advance our understanding of the beginning of our universe by improving the precision of polarization measurements of Cosmic Microwave Background (CMB). We have developed telescope control and bolometer data acquisition systems for a CMB measurement. Also, we developed a new environmental monitoring system, which was integrated into the data acquisition system. Those systems were deployed to a CMB polarization experiment, Simons Array, at the Atacama desert in Chile. The Simons Array experiment started observations in Chile using the data acquisition and transfer systems. Moreover, we also developed monitoring systems for measuring temperatures of experimental instruments and polarization modulation instruments, which can be applied broadly to future CMB experiments.
