Cathodes

SETS is currently engaged in the in-house design and development of reliable and flexible cathodes to serve as plasma sources for various electric propulsion systems

NON-PREHEATED HOLLOW CATHODE SHC60

The hollow cathode is non-preheated cathode modification and has a simpler construction compared to traditionally heated cathodes. The alkali metal salts are used as cathode activator substances in this cathode. The maximum start time is not more than 5 seconds for this modification.The cathode provides up to 2.0 A discharge current at a mass flow rate of the working substance up to 0.05 mg /sec. The power consumption is up to 15 W.

PREHEATED HOLLOW CATHODE SHC70

The structure of this cathode corresponds to the classical scheme of the hollow cathode and includes the start heater and the keeper. The alkali metal salts as the activator material as working substance is a unique feature of the cathode. The using of alkaline metals salts as the material of the activator allows keeping on working efficiency of the product under the conditions of vacuum system depressurization, besides use a high purity gaseous working substance is not required.
