As expected, the example application given is only one option, and this is basically a long-range radiation death ray: > We are certainly aware of the fact that this kind of device can not only target the nuclear bombs but other kinds of weapons of mass destruction and also, unfortunately, any kind of living object including human. If I understand it correctly, from skimming the paper, this depends on the beam passing through earth without interaction and then "emerging" (starting to interact) at a precise point. Is that how these beams work at least in theory, i.e. will a "perfect" beam emerge in a point rather than distributed along a line due to the process being probabilistic? Of course, getting the beam perfect would then be the next challenge. (Conveniently, this part of the problem seems to have been left for a separate publication.)
