This paper presents the experimental setup of the Endurance Test of a Field Emission Electric Propulsion (FEEP) thuster presently underway at the ESTEC Electric Propulsion Laboratory. The setup includes a fully automated 3-D ion beam scanning system to assess the plume current distribution and a triple filament Langmuir probe. The test is aimed at totalling 2000 hours of operation. The criteria behind the test setup are discussed and the experimental arrangement is presented. First operational results are shown.
