Neutrino Beams

I am very supportive of DUNE. We need a flagship particle physics experiment, and DUNE is the best one we are getting in the next 10-15 years. In addition to measuring the CP violating phase, it also will provide a reasonable supernova neutrino observatory.

Despite my support of DUNE, neutrinos are very difficult to pin down and part of this is the fact that the current method to produce a neutrino beam produces neutrinos with a broad energy spectrum. That is why I was very interested a few months ago to read Mono-energetic neutrinos with enough energy to produce a muon.

I was very interested in a neutrino factory and other neutrino beam ideas, but this sounds very promising, and may turn out to be necessary to really utilize our neutrino detectors and observatories.
