HK40 Hall Thruster with electromagnets is tested

The most recent version of the HK40 Hall Thruster with electromagnets has been succesfully tested with the newest coaxial hollow cathode. During the testing the hollow cathode has been placed on a 2D translational stage and its location with respect to the thurster has been varied. Langmuir probe measurements of the thruster plume region have also been carried out. During the testing the magnetic field topology of the HK40 Hall thruster has been varied by changing the currents to inner and outer electromagnets of the thruster.
