Abstract :
We developed a new observing system to improve the performance of the 45-m telescope at Nobeyama Radio Observatory (NRO). The system consists of new receivers, new IF converters, new A/D converters, and a new spectrometer. The technologies developed for ALMA (the Atacama Large Millimeter/Submillimeter Array) were used for many parts (e.g., receivers and spectrometers). With the new system, we are conducting surveys of distant primeval galaxies and line surveys of various targets.
