What is DAEδALUS?

DAEδALUS: Decay at rest Experiment for δcp studies At the Laboratory for Underground Science

DAEδALUS is a proposed phased neutrino experiment which aims to produce many interesting physics results and, ultimately, to search for evidence of CP violation in the neutrino sector. The latter goal is currently one of the most important priorities in neutrino physics because it may help to explain fundamentally important questions about the development of the early universe, such as the observed matter/antimatter asymmetry. As we move towards constructing an experiment to explore this question, we also aim to use each building phase for more new physics, for example, sterile neutrino searches, H2+ dissociation studies, and high-power cyclotron development.

The complete experiment will comprise several accelerator-based modules located at three different distances from a single gadolinium-doped water Cerenkov detector. Each of these modules will then make use of new low-cost, high power proton cyclotrons to produce decay-at-rest neutrino beams. The beam windows are staggered in time so that events measured by the detector can be uniquely identified with one of the neutrino beams. The object will then be to search for evidence of CP violation in the oscillation of muon antineutrinos to electron antineutrinos or ν(bar)μ → ν(bar)e over short baselines of up to 20 km. Possible locations for the experiment are being explored at the moment.

This new type of search, which will complement the work of presently proposed experiments such as the Long Baseline Neutrino Experiment (LBNE) at Fermilab, can provide measurements that will lead to a substantially better exploration of CP violation in the neutrino sector.
