DeltaV: thanks for that shielding pdf. It looks like it will be an interesting read. I should be able to do a better (more accurate) shielding design for my ships :)

Glad to be of help. Radiation calcs are not really my gig, but, assuming Polywell works, shielding mass seems to be the biggest hindrance to putting it in a flying machine. I'm still hoping for some sort of nanotech breakthrough that results in drastically lighter shields. Layers of different materials seems to be a step in the right direction.

Fresnel approach

Thanks, MSimon. Watch your back.

I was reading in a NASA report on space shielding options that they wanted more research into carbon nanostructures loaded with hydrogen (compounds?). One idea was that carbon composites might do double-duty; load-bearing structures and radiation shields.

Maybe boron or could also be used. It would have to yield a really big improvement, however, to justify the added hassle/expense of nanostructures vs. macroscopic layers.

In theory there is no difference between theory and practice, but in practice there is.
