Reliable measurements of electron properties are key for the validation of simulations of Hall
thrusters and similar plasma sources. In this paper, a recently-developed incoherent Thomson
scattering diagnostic is successfully applied to electron property measurement in a low-power
Hall thruster discharge. Investigations of electron properties along radial and azimuthal
directions in both conventional and magnetically-shielded architectures are performed. The high
diagnostic sensitivity gives access to electron property measurements in a plasma environment
with densities as low as 10¹⁶ m^-3. Electron temperatures reaching several tens of eV and drift
velocities on the order of 10⁶ m.s^-1 are measured in the exit plane region. The impact of the
magnetic field (intensity and direction) and discharge voltage are investigated.
