Compact Toroid Formation Using an Annular Helicon Preionization Source
Formation and ejection of compact plasma toroids for high-thrust and high-specific impulse applications are modeled in conjunction with experimental efforts for concept development. in particular, use of field-reversed configuration plasma with an annular helicon pre-ionization source is being investigated. This type of thruster would have high thrust and no need for electrodes or grids that limit lifetime and reliability. Results from modeling the pulsed power system, the FRC formation process, and acceleration indicate that the annular helicon pre-ionization source is ideal for FRC processes to maximize coupling between the pulsed field and the plasma.
