This work presents the near exit plane velocity field of the Busek Company BHT-200-X3 200 W Hall thruster at a single operating condition with a 250 V anode potential. The ionized propellent velocities were measured -- using laser induced fluorescence of the 5d47/2 - 6p35/2 excited state xenon ionic transition at 834.7 nm. Ion velocities were interrogated from the acceleration channel exit plane to a distance 107 mm from the ...
Measurements are presented for the density of ground-state neutral xenon atoms in the near field of a 200W co-axial Hall thruster. The diagnostic strategy employed is a variation of a classical absorption technique, using retro-reflected intrinsic line emission from the resonance 147 nm vacuum ultraviolet (VUV) transition in atomic xenon as a source for absorption. In this way the technique has, in principal, the sensitivity of narrow-band absorption methods Preliminary ...
