The Atacama Large Millimeter-submillimeter Array (ALMA), sited on the high desert plains of Chajnantor in Chile, has opened a new window onto solar physics in 2016 by providing con…
Over seven decades of solar microwave data obtained with Toyokawa and Nobeyama Radio Polarimeters
Masumi Shimojo, Kazumasa Iwai
Monitoring observations of solar microwave fluxes and their polarization began in Japan during the 1950s at Toyokawa and Mitaka. At present (April 2022), monitoring observations co…
OCTAD-S: Digital Fast Fourier Transform Spectrometers by FPGA
Kazumasa Iwai, Yûki Kubo, Hiromitsu Ishibashi +5
We have developed a digital fast Fourier transform (FFT) spectrometer made of an analog-to-digital converter (ADC) and a field-programmable gate array (FPGA). The base instrument h…
