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.

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.
