As the target passes through the magnetic field gradient it effectively experiences a rapidly changing axial magnetic field, which induces strong azimuthal currents in the target liner to implode the fuel and reach fusion conditions. Among other advantages, eliminating the need to pulse the magnetic field coil allows the use of energy efficient superconducting coils in a geometry that more naturally lends itself to in-space propulsion. If successful, the proposed concept will substantially reduce Mars trip times and enable a robust architecture for human solar system exploration.
