Fortunately, Lederman, Schwartz, and Steinberger won the 1988 Nobel Prize in Physics for figuring out how to build a neutrino beam, which is much easier than detecting them. Basically, slam a proton beam into a few feet of something big and heavy. The big heavy stuff will absorb everything else, and leave just a beam of neutrinos, which don't care if you have miles of armor rather than feet.
