New technologies in neutrino physics

Within the last two decades major progress was achieved in experimental neutrino physics. This was only possible due to the constant development of new technologies in this field. Today a very broad progress of technologies can be observed, making possible neutrino experiments at very low energies (i.e. in the sub- MeV regime) until extreme high energies. In this lecture I will try to describe two examples, how new technologies developed within the last years. Both are mainly dealing with low energy neutrinos (i.e. below ≈1GeV), however we will see how this technology may also be expanded to search for proton decays. This contribution will begin with a brief description of neutrino oscillations and the experimental status quo, followed by a short discussion about open questions in neutrino physics. Then the new technology developed for the search of θ₁₃with the three reactor neutrino experiments will be presented, which started data taking in 2011. Finally I will discuss some aspects of a future project utilizing a very large, homogeneous liquid-scintillator volume.
