[Spaceships] Magnetic Shielding above TL8

What I'm actually aiming to protect against are the charged particles that result when a STL craft impacts interstellar atoms at >0.01c. Anything else that gets protected against is gravy.


(About the only non-superscience way I know of to protect against gamma-ray-level EM radiation are to use a high-atomic-weight material, thick enough to absorb secondary impacts; and I haven't been able to make that work with my mass budget. So for this sub-problem, I'm using massively-redundant, fault-tolerant, radiation-hardened computers.)


I've just found a potentially-useful reference; in Ultra-Tech, there's a line that force-fields give an rPF equal to their DR. So an Energy-only screen, which I drop down to TL10, could offer in the neighbourhood of rPF 200 for 25 lbs and $12,500; maybe drop that down to 150 for the TL decrease. Or maybe apply that to Spaceships' force screens.

I'm still open to any other ideas, of course.
