PARKER SOLAR PROBE FIELDS Level 3 Simplified Quasi-Thermal Noise (SQTN) Data (CDF)

This data set contains Parker Solar Probe FIELDS Level 3 Simplified Quasi-Thermal Noise data, derived from power spectra (10.5 kHz to 1.7 MHz) acquired by the low-frequency receiver (LFR) of the Radio Frequency Spectrometer (RFS) when connected to V1V2 dipole antenna. The technique of QTN spectroscopy consists of using the power spectrum of the voltage induced on an electric antenna by the particle quasi-thermal motion, measured by a radio receiver connected to an electric antenna. The signature of the electrons is a line at the electron plasma frequency, which leads to the total electron density (proportionnal to the square of electron plasma frequency), whereas the shape of the line reveals the electron kinetic temperature, as well as its themral (core) and suprathermal components.
