Radio mission instrumentation team<\/h2>\n\n\n\n

Radio astronomy studies the invisible Universe by detecting radio waves emitted by celestial objects. ATC develops instruments for the radio telescopes of NAOJ research facilities, including the Nobeyama Radio Observatory (NRO) in Nagano, Japan, and the Atacama Large Millimeter\/submillimeter Array (ALMA), built in northern Chile, through an international collaboration among East Asia, North America, and Member States of the European Southern Observatory, with the support of the Republic of Chile. ATC also provides support for the development of radio astronomy instruments by universities and related institutes.<\/p>\n\n\n\n

The Advanced Technology Center has developed ultra-sensitive superconducting receivers in three frequency bands (bands 4, 8, and 10) for ALMA , and completed manufacturing and shipping a total of 219 units in February 2014. The shipped receivers are currently integrated on antennas and used for astronomical observations. The Advanced Technology Center maintains receiver test facilities for each band for receiver maintenance.<\/p>\n\n\n\n
