Depending on the temperature the coil can handle before it quenches, the rate of fire and the size of the pellet, it seems somewhat doable.Ģ) Your coils would need backing, so they don't burst from the strength of their magnetic field. That means that between your superconducting coil and the reaction chamber, you'll want some kind of heatshield. Some issues:ġ) You still need to absorb the waste heat from the reaction. The fusion products are expelled the other way, providing thrust. From the POV of the pellet, the magnetic field slams into it, heats it and compresses it, and just as the particle crosses the crux of the field, it fuses. A pellet of Deuterium/He-3 is wrapped in a lithium foil, then shot out the back towards the magnetic field at say 1000 km/sec (I've heard that as a ballpark for impact fusion). Perhaps, they use extremely powerful magnetic fields around a loop as their exhaust port. I've thought about this myself, but reached a somewhat different conclusion given the numerous problems encountered by laser-driven fusion on Earth: impact fusion. In other words, the fusion output can be increased 10 times and all the performance falls back in line with what was calculated so far. The 'multiplier' mentioned earlier jumps from 46,300 to 461,300, just over 10 times better than before. To adjust for this while maintaining the same performance, we would simply state that the fusion reaction is ignited 10^0.5: 3.16 times further away, or 948m. If we assumed a ten times greater density for the Rocinante, for example, we would have an empty mass of 2500 tons. A stronger field allows for fusion products to be redirected from further away, so that an even smaller portion of the harmful energies are intercepted. The variable will be the ignition point distance from the spaceship and therefore the magnetic field strength of the coils in the 'nozzle'. This proposed design can be easily scaled to adjust for different figures for mass, acceleration and deltaV. Of 21.2 thousand kilometres in about 10 minutes, and 0.76 million kilometres in
