Lately, I was studying the possible methods for protecting astronauts and onboard equipment in a spacecraft from space radiation which mainly comprises solar particle events (SPEs) and galactic cosmic radiation (GCR) and poses the major hurdle. After reading a lot of papers on this topic, I am convinced that magnetic shielding is one of the best choices and an active area of research. I encountered the most effective shape of the shielding to be a hybrid torus. But unfortunately, none of the papers properly describe the hybrid torus. Can anyone please help me understand the geometry of hybrid torus and how it is effective as compared to other shapes regarding active magnetic shielding against space radiation?
