The possibility of determining the rate of erosion of the discharge chamber of a thruster with closed electron drift and extended zone of acceleration using the method of emission spectroscopy

Based on the method of emission spectroscopy, an approach is suggested to the investigation of the rate of erosion of the discharge chamber of a thruster with closed electron drift and extended zone of acceleration. Experimental investigations are performed of the rate of erosion for different topologies of magnetic field. The resultant data are compared with the results of direct measurements of the rate of erosion.
