Research Abstract

To reveal the cosmic structure formation, realization of wide field and sensitive submillimeter wavelength observations of distant galaxy clusters and protogalaxies along the large scale structure is required. Therefore, development of a sensitive large array cryogenic detector utilizing superconducting transision edge sensor "TES bolometers" was conducted and the array detector was successfully readout by efficient multiplexing method.
