Abstract
This paper presents the scope of challenges which are faced in development and manufacturing of the cathode-compensator dedicated for micro-SPTs, and possible ways of how to overcome them. As compared to standard models, such a cathode shall be smaller in dimensions, shall have a lover propellant flow rate, as well as lover heater power and power consumption when self-operated; and it shall be able to operate in the current range of 0.3…1A or lower.
