I think this system is worth studying. IF both parts leave Sol by maser
sail, and separate at the halfway point. with the decellerator keeping
the maser sail (using it as an antenna converting the maser to elec) and
blasting (new twist) fusion fuel right down the Explorer's throat, i
think it might work.

I think in order to work, it needs to combine your explorer drive with my
maser sail. The one big problem I see is when the decellerator's
velocity overcomes the exhaust velocity. the ions would then be moving
toward TC with some residual velocity. Provided this is small enough,
this just might work. Let me think on this.
