The Next Bubble to Burst

In 1968 Ray Davis devised an experiment to study the neutrino emission from the Sun. This set off 40 years of detector development aimed at understanding these particles and explaining what Ray Davis' experiment had dubbed the Solar Neutrino Deficit Problem. The story is not yet concluded. Over 99% of the total solar neutrino flux, those neutrinos coming from proton-proton fusion reactions in the Sun, have not yet been detected in real-time. This talk will give a brief introduction to the history of neutrinos and their detection and introduce the design of a novel new detector technology being developed which takes advantage of “electron-bubbles” to access this low energy part of the solar neutrino spectrum.
