7 ECR Thruster Principle ECR source + Plasma acceleration in a magnetic nozzle ECR effect: application of an EM field at electron cyclotron frequency at 2.45 GHz, B=875 Gauss ce eb m e Efficient ionization of the propellant gas Principle of operation: ECR discharge heats the electrons (10s of ev) Hot electrons «blow up» the plasma Ions follow (dense plasma) More electrons acceleration: gyrokinetic conversion 7 neutral plasma coming out cathodeless thruster
8 Thruster physics: position among electric thrusters Thrust Thrust Thrust Thrust B E E B Magnetic nozzle E B E GIE FEEP ES BP-ES BP-GIE HET HEMP MPD PPT PIT ECR HPT ICR (VASIMR) 8 Electrostatic thrusters GIE = Gridded Ion Engine FEEP = Field Effect Electric Propulsion ES = ElectroSpray (=colloid) BP = bipolar HET = Hall Effect thruster HEMP = High Efficiency Multistage Propulsion Neutralizerless («cathodeless») thrusters MPD = Magneto Plasma dynamics PPT = Pulsed Plasma Thruster PIT = Inductive Plasma thruster ECR = Electron Cyclotron Resonance HPT = Helicon Plasma thruster ICR = Ion Cyclotron Resonance
9 Detailed advantages of ECRA Characteristics System impact Advantage Lower recurring cost No Neutralizer Removal of the neutralizer as a critical component (failure, lifetime) Simplified PPU Single fluidic line Higher reliability Longer lifetime Lower recurring cost Higher reliability Lower recurring cost Lower recurring cost (ground testing) Low Xe purity acceptable Lower cost of flight propellant No fragile or complex parts (no grids, etc...), low part number Magnetic nozzle Microwave power = only electrical input Reacting gases acceptable (e.g. O 2 ) Simple design Thrust vectoring Ambipolar acceleration Magnetic shielding Simplified PPU DC uncoupling of thruster and PPU MW generator = new element in PPU Lower cost Xe tank Compatible with air breathing Compatibility with all alternative propellants. Lower recurring cost Higher reliability Longer lifetime Lower recurring cost (no gimbal mount needed) No Child law limit to thrust per unit area (similar to HET) High efficiency Longer lifetime Lower recurring cost Lower recurring cost (no galvanic isolation of PPU) Increases cost 9
10 Technical hurdles PPU efficiency: off-the-shelf microwave generators have efficiencies < 70% there are new solid state solutions emerging with up to 90% efficiency at low power (~5W). Magnetic torque: the DC magnetic field created by the permanent magnets using thrusters in pair, with reversed magnetic field, or placing a magnet creating an opposite torque on the satellite plateform. EM field: low emission when plasma ON (not visible on detector). Needs to be quantified. 10 Magnet heating: current permanent magnet technologies (samarium-cobalt for example) can go to high enough temperatures Reflected power: some theories on ECR thruster show 50% power reflection: only the RCP wave (right circularly polarize) would be absorbed. experimentally we routinely achieve 95%. No show stopper
11 Developing an ECR Thruster : challenges - Plasma physics more complex than other thrusters (wave/ionisation/acceleration coupling): difficult to model. Full model not yet available. Magnetic nozzle challenging. IONIZATION AND ACCELERATION ZONES Growing modeling difficulty DC FREQUENCY MHz or pulsed µs ( >L) Separated GIE ICR-VASIMR Coupled HET HEMP MPD HPT PPT PIT - No direct experimental knowledge of the total current and of the ion energy: need for ion beam probes and very refined experimental characterization GHz ( <L) ECRA 11 - Good vacuum levels needed: magnetic nozzle much larger than the source and extends in the vacuum tank. need to be < 10-5 mbar (HET can work up to 10-4 mbar) need 10 times higher pumping
12 Example of parameters to investigate Magnetic topology: larger ECR zone (parallel B region) magnetic mirror at the exit: control of energy, better ionization magnetic mirror at the entrance: reduce losses to back wall B field variations at the exit: vectoring Microwave coupling: antenna, waveguide,. Develop low and high impedance coupling (issue of matching) 12 Effect of frequency: try 4 GHz, 1 GHz Effect of wall material: conductive vs dielectric, spuutering/secondary emission yield, Effect of scale-up : 200W then 1 kw One of the questions for scale up: should the wavelength (ie frequency) scale with the thruster?

20 Work package achievements #
21 WP3 Modeling: hybrid code The hybird code (fluid+pic) tailored to the ECR thruster is being developped by UC3M. The SURFET code is subdivided in 4 modules: Plasma-wave interaction module: 2D cold-plasma dielectric tensor code (module #1 of SURFET). Kinetic submodels and/or information from ROSEPIC will be used to model accurately the resonance regions. Ion/neutral PIC-DSMC subcode: 2D quasi-structured Particle-In-Cell code based on magnetic grid. Will include ionization, recombination, excitation and transport dynamics Electron fluid subcode: magnetized electron fluid with energy balance. Fluid electrons (instead of PIC) reduce substantially the computational complexity, at the expense of a minor loss of physical detail Magnetic nozzle module: two-fluid, 2D code of the plasma expansion in the magnetic nozzle 21 Perfect conductor PML Magnetoplasma options: Cold + collisions Kinetic damping j a B 0 IEPC Preliminary version of Wave-plasma module planned for M12 Ongoing work IEPC Ongoing work
22 22 WP3 Modeling: PIC code Development of a PIC/MCC code ES-PIC for Low pressure plasma modeling DSMC capability: vacuum chamber analysis EM-PIC for ECRA Features : Serial / 2-level parallelism (MPI/ OpenMP) Block cartesian mesh Arbitrary geometry : immersed boundary method Tiled structure Vacuum chamber simulation, 72 cores ~ particles 22 Status of the Code All particle modules developed 3D DSMC test done Maxwell Solver : 1D done 2D 3D parallel version under development P.Q. Elias, Advances in the kinetic simulation of the microwave absorption in an ECR thruster, IEPC D PIC modeling
23 WP4: Thruster design optimization (1/2) The goal is to improve the understanding and performances (efficiency, thermal management, lifetime) Achievements: - Developped a thrust balance measurement for reliable performance assessment (waveguide-to-coax feedthrough with no mechanical force) - Parametric experimental study: antenna length, diameter, source length Antenna length 23 Antenna diam. - Effect of background pressure Source length.
24 WP4: Thruster design optimization (2/2) - Measurement of plume properties, with Langmuir / Faraday probes - Combination with LIF measurements Achievement: Measurement of acceleration voltage profile - Development of new techniques: plasma diamagnetism 24 Achievement: Measurement of perpendicular electron temp. (anisotropic distribution)
25 WP6: Scale up and erosion Thrust balance for high power thruster in JUMBO facility: cannot measure 5mN for 200W test in MINOTOR. Achievement: A thrust balance dedicated to low thrust measurements (1-10 mn) has been acquired, to be used for MINOTOR. It was manufactured by the Advanced Space Technology (AST) company, shared between German Space Center (DLR) Goettingen and JLU Giessen. It consists of an aluminium frame onto which a parallelogramstructure is attached by (bending) bearings. The thrust is measured by a moving coil method where a counterforce is generated which compensates the thrust. Ongoing work: Tests with coil steps 1-10 mn Integration of the thrust balance into the Jumbo test facility Assessment of the quality of the calibration scheme Thrust measurements with a RIT-10 Determination of thrust balance parameters (resolution, temperature drifts, offset, etc) 200W scale-up work at ONERA 25
26 WP7: MW generator PPU efficiency is a major factor in the thruster system efficiency. No off-the-shelf MW generator with higher than 60-70% eff. BUT new technology + Thales patent can reach high power 85-90% efficiency. To be developped in WP % efficient. Structure of the microwave generator planned for MINOTOR. Achievement: 25W PA 60% efficiency so far, efforts to improve the efficiency ongoing.
27 WP8: System Impact Focus on the simplification of the PPU: ECRA requires: - No cathode - No coil - No galvanic isolator (thruster floating) HET ECRA Achievement: 27 Saving of >50% of the PPU Cost. But need to add MW amplifier Cost (SSPA).
28 WP9: Requirements and validation Ongoing work: - Gathering reference data for thruster performance comparison - Following ECRA performances. Setup a server to put thruster data for sharing between experimental and modeling teams 28
