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…
DESHIMA on ASTE: On-sky Responsivity Calibration of the Integrated Superconducting Spectrometer
Tatsuya Takekoshi, Kenichi Karatsu, Junya Suzuki +36
We are developing an ultra-wideband spectroscopic instrument, DESHIMA (DEep Spectroscopic HIgh-redshift MApper), based on the technologies of an on-chip filter-bank and Microwave K…
First light demonstration of the integrated superconducting spectrometer
Akira Endo, Kenichi Karatsu, Yoichi Tamura +36
Ultra-wideband 3D imaging spectrometry in the millimeter-submillimeter (mm-submm) band is an essential tool for uncovering the dust-enshrouded portion of the cosmic history of star…
Planar Superconductor-Insulator-Superconductor Mixer Array Receivers for Wide Field of View Astronomical Observation
Wenlei Shan, Shohei Ezaki, Jie Liu +3
We present a conceptual framework of planar SIS mixer array receivers and the studies on the required techniques. This concept features membrane-based on-chip waveguide probes and…
The Atacama Large Millimeter/submillimeter Array (ALMA) Band-1 Receiver
Yau De Huang, Oscar Morata, Patrick Michel Koch +29
The Atacama Large Millimeter/submillimeter Array(ALMA) Band 1 receiver covers the 35-50 GHz frequency band. Development of prototype receivers, including the key components and sub…
A New 100-GHz Band Two-Beam Sideband-Separating SIS Receiver for Z-Machine on the NRO 45-m Radio Telescope
Taku Nakajima, Kimihiro Kimura, Atsushi Nishimura +11
We have developed a two-beam waveguide-type dual-polarization sideband-separating SIS receiver system in the 100-GHz band for {\it z}-machine on the 45-m radio telescope at the Nob…
