I think it is the cosmic ray flux that Circovic is talking about, but the paper may explain that. If, on the other hand, they have a reasonable configuration in mind for the shield, then it may be worth adapting to OA. Any shield would necessarily be quite thin, even if it only just covered each inhabited planet. Such a thin shield would not stop cosmic ray photons - but a magnetic shield could deflect charged particles.
