Plans for the Reactor Neutrino Experiment Double-CHOOZ

A new experiment at the Chooz reactor in France is being planned to measure anti-neutrino disappearance which extends sensitivity to the neutrino oscillation parameter theta-13. The best current limit on theta-13 comes from the previous reactor neutrino experiment CHOOZ. The new experiment, a collaboration of European and US physicists, will use two 15 ton detectors to reduce most systematic errors. If fully approved in 2005, it will reach the CHOOZ sensitivity by early 2008, and sine-squared of twice theta < 0.03 by 2010.
