Abstract

The Large Millimeter and Submillimeter Array (LMSA) being planned at the National Astronomical Observatory of Japan (NAOJ) is a high priority plan for the future large-scale ground-based astronomical facility coming after the Subaru telescope. The LMSA will consist of 50 10-m antennas. The planning of the instrument places a special emphasis on high- resolution and high-sensitivity observations at submillimeter wavelengths. Efforts at Nobeyama Radio Observatory (NRO) have been focused in the site testing at the two candidate sites in Northern Chile and engineering developments, especially in antenna design, submillimeter mixers, high-speed digital technology for wide-band correlator, and phase calibration methods. A possible joint-array operations with other large array projects is under discussion.
