Langmuir probes are used to determine the electron energy probability function (eepf) at different axial positions, revealing the non-local character of the distributions. The second part of the paper details a combined diagnostics of non-intrusive diamagnetic loop measurements and laser induced fluorescence to estimate the perpendicular electron temperature inside the plasma source. Averaged perpendicular electron pressure, plasma density, ion velocity at the exit plane and perpendicular electron temperature are determined as functions of the mass flow rate.10application/pdfengAnisotropic plasma propertiesMagnetic nozzle expansionElectron cyclotron resonance thrusterECR thrusterconference proceedingsAeronáuticaopen access110CC/0000028191
