The ion far-field plume of the 100 W-class ISCT100-v2 Hall Thruster (HT) has been characterized by means of an E×B probe. The influence of operating parameters on both velocities and fraction of different ion species was investigated over a 40 • circular arc. E×B spectra were thus recorded for different background gas pressures, discharge voltages, angular positions and propellants (namely xenon and krytpon). The probe alignment is also discussed in this contribution, since measurements were recorded for the probe aligned with both the thruster centerline and the thruster mid-channel.
