Outline of Final Research Achievements

Terahertz waves, located in the gap between radio waves and visible light, have been recognized as a potential tool for the detection of the red-shifted continuum radiation from first stars in the early universe. We developed a terahertz-wave detector (receiver) with high sensitivity, broadband detection and large array capability for the all sky survey of the Cosmic InfraRed Background (CIRB). Concretely, we developed a microwave kinetic inductance detector (MKID) array based on not conventional metal superconductors but nitride superconductors. We also automated the data acquisition system from the cooling through the measurement. The larger format array offers the further improvement of the imaging capability.
