Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Corrugated horn & Optics covering 210-375 GHz band
Yasumasa Yamasaki, Sho Masui, Hideo Ogawa +21
The corrugated horn is a high performance feed often used in radio telescopes. There has been a growing demand for wideband optics and corrugated horns in millimeter and submillime…
Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Receiver development & the first light of simultaneous observation in 230GHz and 345GHz bands with an SIS-mixer with 4-21GHz IF output
Sho Masui, Yasumasa Yamasaki, Hideo Ogawa +22
We have developed a wideband receiver system for simultaneous observations in CO lines of J = 2-1 and J = 3-2 transitions using the Osaka 1.85-m mm-submm telescope. As a frequency…
Waveguide-Type Multiplexer for Multiline Observation of Atmospheric Molecules using Millimeter-Wave Spectroradiometer
Taku Nakajima, Kohei Haratani, Akira Mizuno +5
In order to better understand the variation mechanism of ozone abundance in the middle atmosphere, the simultaneous monitoring of ozone and other minor molecular species, which are…
Wideband 67-116 GHz receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, V. Belitsky +43
ALMA has been operating since 2011, but has not yet been populated with the full suite of intended frequency bands. In particular, ALMA Band 2 (67-90 GHz) is the final band in the…
Experimental Study of a Planar-integrated Dual-Polarization Balanced SIS Mixer
Wenlei Shan, Shohei Ezaki, Keiko Kaneko +3
A dual-polarization balanced superconductor-insulator-superconductor mixer operating at 2 mm wavelength is realized in form of a monolithic planar integrated circuit. Planar orthom…
Wideband 67-116 GHz cryogenic receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, L. Testi +25
The Atacama Large Millimeter/sub-millimeter Array (ALMA) is already revolutionising our understanding of the Universe. However, ALMA is not yet equipped with all of its originally…
