Strange how the paper chose aluminum GCR shielding, not something more sensible like water and/or polyethylene (often in the form of supply mass you already carry).
It's long been known that aluminum shows a local minimum around 30 g/cm^2. Water and PE don't have this problem.

- fwlr 3y agoOh, if it’s true that aluminum alone has this local minimum issue, then the paper is even weaker than I initially thought. I took them at their word when they said other shielding may have better coefficients but still suffers from the same general limitation, but your paper makes it sound like that’s a false (but commonly accepted) assumption.
