N2 - A Wien filter has been developed to characterize the ejecta plume of a 500 Watt Hall thruster. Wien filter, also called as E×B probe, is a velocity filter utilizing an electromagnetic force that acts on the charged particles for measurements. The ejecta plume characterizations of Hall thruster are essential parameters that should be characterized to investigate the performance of the thruster. However, the measurement accuracy of Wien filter is often degraded by the fringe field effect. Therefore, in this research, a field compensation method has been applied to minimize the negative impact from the fringe field. ANSYS Maxwell is used in the preliminary design phase to simulate the electromagnetic field topology to define the Wien filter configuration.
