Scientific paper

A new 4 m millimeter wave telescope has been constructed at the Department of Astrophysics at Nagoya University. The telescope is usable in a frequency range between 80 and 300 GHz. At the present time, the telescope is equipped with a cooled diode mixer with a receiver noise temperature of 200 - 250K (DSB) tunable in a frequency range between 80 and 120 GHz and with acousto-optical spectrometers. The method of fabrication of the primary reflector and the present status of the telescope's performance are described. Some observational results are presented to illustrate its performance.
