| 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.
