Abstract : Turbulence Heating ObserveR (THOR) is the first mission ever flown in space fully dedicated to plasma turbu-
lence. The search-coil magnetometer (SCM) of THOR is a triaxial dual-band antenna dedicated to measuring the
magnetic field fluctuations in the frequency range [1Hz,4kHz] and [1,200]kHz. THOR/SCM has a long heritage
from earlier space missions such as Cluster, Themis, MMS, BepiColombo, Taranis, Solar orbiter and Solar Probe.
In comparison to those missions, the SCM of THOR has a higher sensitivity level, which makes it capable of mea-
suring very low amplitude magnetic fluctuations, in particular in the solar wind. Those measurements are crucial
to address the problem of turbulence and energy dissipation at electron scales, a central goal of the THOR mission.
