Plasma injectors for onboard use

Reliable and operationally convenient flight-designed alkaline plasma injectors are applicable for space experimentation on:
- space plasmadynamics;
- spacecraft charge control;
- plasma contactor of tethered systems;
- problem of interaction between RF signals and plasma plumes of electric thrusters.

Basic versions of hardware have been qualified to meet the launch requirements generally applied to Soviet boosters payloads.
Flight hardware is provided with certificated test equipment which could be delivered on demand.
EPICURE arcjet of multiplex switching was flight tested on Kosmos satellites.
Single switching muniature arcjet OKA was used for high altitude active experiments on board meteorogical rocket probes.

Both EPICURE and OKA hardware could be updated to meet other requirement in the power consumption range from 1 to 4 kW on demand.
