The HEMP-Thruster Module for LEO applications
The HEMPT EV0 module (HTM EV0), is composed of a thruster (THR) and of a neutralizer (NTR) compensating the resulting electric charge of the spacecraft. THR integrates the magnetic system, the discharge channel, the anode, which performs the function of a gas distributer in the discharge channel too, the radiator, which as a part of mechanical interface. All necessary electrical connections are performed inside the module, in the rear part, with the heat-resistant cables.
These cables are electrical interface to the satellite systems or GSE. The gas interfaces are the anode and the cathode gas lines. The thermal design of HTM EV0 allows for an effective “no heat sink” to the satellite.
HTM EV0 operating anode power range is 200 W … 700 W, with the thrust up to 32 mN. HTM EV0 is capable to operate under anode voltages from 300 V to 800 V, reaching the Isp of 2000s. HTM EV0 operates efficiently both with gases Xenon and Krypton in the whole range of operating parameters
