Ka-band cryogenic low-noise receiver of the Misasa 54 m antenna for deep-space communications and radio astronomy

Masato Tsuboi Yutaka Hasegawa Go Tabuchi Yasuhiro Murata Koji Yuchi Tomoaki Toda Takashi Uchimura Kimihiro Kimura Takashi Kasuga

Publications of the Astronomical Society of Japan 75(3) 567-583 2023年4月 [査読有り]

We built a Ka-band dual-circular-polarization low-noise receiver for the Misasa 54 m parabola antenna in Misasa, Japan. The antenna is designed to be combined with a transmitter and receiver system at the X band (around 8 GHz) and simultaneously w...

Abstract

We present a detection of a bright burst from the fast radio burst (FRB) 20201124A, which is one of the most active repeating FRBs, based on S-band observations with the 64 m radio telescope at the Usuda Deep Space Center/JAXA. This is ...
