Laser-induced fluorescence of the neutral-xenon 6s[3/2]206p[3/2]2(3P2-1D2) transition at 823.2nm and the xenon-ion 5d[3]7/26p[2]5/20(4D7/2-4P5/2) transition is used to measure plasma parameters in the plume of alaboratory-model xenon Hall thruster. The Hall discharge operates nominally at 62V, 4.2A, and 3.2mgs-1 xenon flow, with an overall thruster power of 320W. Atunable semiconductor diode laser and an Ar+-pumped dye laser are used to probe the respective excited-state transitions. Axial velocity measurements are made at anumber of axial and radial locations up to 4.5cm downstream of the thruster-exit plane and under avariety of thruster operating conditions. Neutral velocities from 100ms-1 to 400ms-1 and ion velocities as high as 12kms-1 are calculated from measured Doppler shifts. The charge-exchange phenomenon evidently does not significantly affect the xenon neutrals. The spectral-line shapes of the ion indicate aspread in ion energies through anon-Maxwellian distribution of axial velocities. Neutral kinetic temperatures of 500(200)K are observed under standard operating conditions. Zeeman and Stark effects on the spectral-line shapes, from the thrusters magnetic and electric fields, are not substantial. The measured line center of the ion transition is 16521.23(0.02)cm-1.
