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 ##IMG## [http://ej.iop.org/images/0963-0252/29/3/035015/psstab6c42ieqn1.gif] {${10}^{16}\,{{\rm{m}}}^{-3}$} .
