| Outline of Final Research Achievements |
In this research, we have developed a superconducting MKID (microwave kinetic inductance detector) camera for wide field-of-view millimeter/submillimeter-wave astronomical observations. MKIDs composed of superconducting LC resonators sense the change in superconductive impedance when Cooper pairs are broken into quasi-particles by millimeter waves. A double slot antenna for receiving submillimeter waves and silicon substrate lens-array are combined to increase light collection efficiency. We have also developed a new FFT based MKID readout system and a compact cryogenic system consisted of large diameter silicon lenses (4K objective lens) and 1K eyepiece). The MKID camera covers 2000 pixels with 4 modules of 600 pixels. To confirm the feasibility as an observation system, a demonstration of the camera was carried out at Nobeyama 45 m telescope.
