Summary
The Rafael Ltd R-200 thruster is a Hall Effect Thruster (HET) suitable for low to medium mass satellite platform (< 500kg) with Xenon as propellant.
The non-conventional configuration of having an elongated discharge channel and co-axial anodes helps overcome the low mass utilization efficiency issues. The system is fully space-qualified and has been subjected to vibration, shock and full lifetime tests.
During the development phase, the thruster underwent proof-of-concept tests, selection of wall material, experimental and numerical validation of physical mechanisms, performance testing, and thermal, magnetic and structural simulations of thruster engineering model.
The engineering model was produced and mapped for full performance during this phase, followed by a Qualification Model (QM) production of the thruster. The QM is tested for a steady state performance characterization, shock and vibration test, ignition tests and a 75 kN-sec (1,500-hrs) endurance test.
The lifetime, reliability and readiness time were increased using the low current heaterless hallow cathode. Unlike the traditional HET, this cathode design eliminates the need for power-consuming heater power supply.
