Abstract:
The Ion Cyclotron Resonance Heating(ICRH)stage is the RF-booster of the Magnetoplasma Rocket Engine(MPRE)in which the RF power is directly coupled to ions. The heating effect of the ICRH stage has an important influence on the thrust performance of the engine. A multi-fluid, two-dimensional, axisymmetric model was developed to study the heating effect of ICRH stage and the helicon plasma source of MPRE together with the ICRH stage of different input parameters were simulated. The results show that the operation mode of helicon plasma source changes continuously during the discharge due to the evolution of the the deposited power. The mode conversions are accompanied by the electron temperature peaks and the plasma density rises dramatically. After the ICRH input is turned on, the electron parameters are basically unchanged while the ion temperature increases significantly, which indicates the ICRH stage has an obvious heating effect on the ions and the ion temperature increases with the amplitude and the turns of the ICRH input current.
