Status Report on Double Chooz

Abstract

Double Chooz main target is to measure Theta13 oscillation parameter by comparing reactor neutrino fluxes in two identical detectors located respectively at 400 m and 1 km away from the 2 Chooz reactor cores. The far detector is now under construction, while we have just completed the design phase of the near one. In this report I will discuss the detector principle, sensitivity and its present construction status.Comment: 4 pages, 5 figures, proceedings of "44th Rencontres de Moriond", "Electroweak interactions and unified theories" session, 7-14 March 2009, La Thuile (I
