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″.展开更多

The frequency independent matching of Gaussian beam is applied to design the quasioptical system with two focusing elements for each band, respectively. The emphasis is on the design to be satisfied with two bands simultaneously. The beam measurement system is also developed to measure the quasioptical system and their components as well as to align the quasioptical elements. We have measured the intensity distributions of the Gaussian beam in the transverse plane and the variations of the beam widths along the propagation axis near the Cassegrain focus. The measured results are also compared the theory.展开更多
