The erosion of the ceramics made of Al2O3 of the SPT20 Hall effect thruster manufactured by the National Aerospace University "KhAI", has been studied by an optical method. The ratio of Al I, Xe I, Xe II emission lines was analysed using actinometry and coronal assumptions. The erosion rate of the ceramics has been evaluated for different operating conditions for the thrusters.

The series of low power Hall effect thrusters (LPHT) SPT-20M was developed and manufactured in STC SPE of the National Aerospace University "KhAI". The main aim was to create a thruster with high performances: high specific impulse and the efficiency up to 40%. During SPT-20M experimental research a number of tests was made. The LPHT magnet system was investigated by taking into account construction thermal conditions. The experimental results show that final model SPT-20M6.1 has good enough performances with respect to the power consumption, which is lower than 100 W.
