Abstract

We have developed the dual channel receiver with 100GHz and 150GHz band, which is used to make the simultaneous observation with two bands.The SIS mixers are used in both bands. The constructed dewar for receiver has the performance with the vacuum of 10^-8 Torr and the temperature of 4.2K.The receiver noise temperature is 50K (DSB)for 100GHz band and 80K (DSB)for 150GHz band, respectively.In order to achieve the simultaneous observations, the quasioptical system is precisely designed, and also evaluated by the measurement in the laboratory.We have observed the various sources using this receiver since October 1998.The relative pointing offset between two bands is 3".
