摘要

Ion thrusters are bright light sources allowing a spectral analysis in a short time without disturbance of the plume. rnAccordingly, the light emission of a Thales HEMP3~) thruster DM6 was studied while the performance of the thruster was investigated in the JUMBO fest facility of the Giessen University. The front end of a light waveguide was positioned in the demagnified image of the thruster exit diaphragm and its other end fixed in the entrance slit of a monochromator of 30 cm focal length, equipped with a CCD as detector. rnThe HEMP thruster was mounted on a thrust balance. The angular distribution of the emitted ions could be monitored by a three axis scanner. Mass flow and discharge voltage were varied during the performance test. The collected spectra contain lines from neutral, singly and doubly charged Xe serving as propellant. The dependence of the relative intensities of selected lines on the discharge parameters will be discussed.
