Measurements of the magnetic field fluctuations in the Solar Orbiter project

Abstract : We estimated the characteristic amplitudes and frequencies of different kinds of waves in the Solar wind on the characteristic distance of the order of 0.2 AU that corresponds to the orbit of the Solar Orbiter. These estimates are based on the measurements of Helios I and 2 satellites. On this basis we have evaluated the experimental requirements for the magnetic field sensors onboard of the Solar Orbiter. We present the characteristics of the search coil magnetometers that are developed in the LPCE. In addition to traditional search coils we present the new magnetic loop antenna characteristics that can be used for the high frequency wide band magnetic field fluctuations measurements in the range 10 kHz-20 MHz.
