Abstract:
The Radio and Plasma Wave instrument (RPW) for Solar Orbiter includes a Time Domain Sampler sub-unit (TDS) designed to capture electromagnetic waveform measurements of high frequency plasma waves and antenna voltage spikes associated with dust impacts. TDS digitizes three components of the electric field and one magnetic field component at a sampling rate of 524 kHz and scans the obtained signal for plasma waves and dust impact signatures. The RPW instrument, including TDS, has been operating and collecting scientific data since shortly after the launch and through the first Solar Orbiter perihelion in June 2020. In this presentation, we will introduce the operation modes and data products of the TDS instrument and discuss observations of multiple plasma phenomena in the solar wind between 0.5 and 1 AU: Langmuir waves including those associated with in situ type III bursts, low frequency ion-acoustic waves and dust impacts.
