in a kinematic region. The last column headed MPS+MPD adds a magnetoplasma dynamic thruster (MPD) that has a higher thrust gain as determined by experiment and simulation. Further details are in the section for the specific design. For designs other than MPS and MPS+MPD, the thrust gain is the achieved force from the first row divided by the force of a magnetic sail alone in the second row. The magnetopause distance (m) and the coil radius (m) are design parameters. Equation with defines the magnetic field near the coil(s) as (T). The superconducting coil designs used a critical current density =2x106 (A/m) to account for warmer temperatures in the solar system. The plasma magnet uses AC power and cannot use a superconducting coil and assumed an aluminum coil with material density = 2,700 kg/m3 and coil wire radius =5 mm. All other designs assumed a superconducting coil with material density =6,500 kg/m3, coil wire radius =5 mm, and critical current 1.6 x106 A, above which the coil becomes a normal conductor. The magnetopause distance and coil radius for superconducting-coil based designs were adjusted to meet this critical current constraint. The values for the plasma magnet used a value of for =2 selected to minimize time to velocity and distance. The MPS values for and were chosen to match the thrust gain from simulation and scaled experimental results and meet the superconducting-coil critical current constraint. Equation gives the physical coil mass (kg) assuming a coil wire radius =5 mm. Equation gives the plasma magnet alternating current . Equation gives the direct current with =2 for all other designs. The plasma magnet RMF uses the input alternating current (kA) to rotate electrons in captured plasma to create an induced direct current disc carrying kA as defined in equation . Designs with a superconducting coil do not require continuous power (but may require power for other functions, such as cooling); however, the plasma magnet design requires a continuous power source as specified in equation . An estimate for the plasma magnet power supply mass assumes ~3 kg/W for nuclear power in space. Other mass was assumed to be 10 tonnes for MS and 1 tonne of other mass for plasma magnet and MPS. Acceleration is the thrust force (N) from the first row divided by the total mass (coil plus other). An optimistic approximation is constant acceleration (m/s2), for which the time to
