    摘要： According to various embodiments, a system for using magnetic reconnection to accelerate plasma is disclosed. The system includes a pair of electrodes including two concentric rings separated by an electrode gap and held at different electrostatic potential by applying a voltage to generate an inter-electrode electric field. The system further includes a plurality of magnetic coils configured to produce magnetic field lines that connect the pair of electrodes. The system additionally includes a gas injector configured to inject gas into the electrode gap, the injected gas being partially ionized by the inter-electrode electric field to generate a poloidal current that flows along open magnetic field lines across the electrode gap. A total Lorentz force causes oppositely directed magnetic field lines to be expanded around a region of the gas injector to further create an azimuthal current in the form of an axially elongated current sheet that is unstable such that the axially elongated current sheet reconnects and breaks into plasmoids.

    摘要： Systems, devices, and methods generating a plasma flow are disclosed. A method may include applying energy that alternates between being at a base level for a first duration and at a pulse level for a second duration according to a controlled pattern, generating a plasma flow having a directional axis, and discharging the plasma flow alternating between a base configuration and a pulse configuration according to the controlled pattern. The plasma flow in the base configuration may have (1) a first temperature at the outlet and (2) a first flow front that advances along the directional axis. The plasma flow in the pulse configuration may have (1) a second temperature at the outlet that is greater than the first temperature and (2) a second flow front that advances along the directional axis at a speed greater than the first flow front.
