Description
The Double Chooz Experiment aims at the measurement of the only not-yet-determined neutrino mixing angle θ13 using neutrinos from the commercial nuclear reactors in Chooz, France. Precise measurement of this angle is highly important in order to direct the formulation of unification theory and moreover, the feasibility of future leptonic CP violation parameter observation. Liquid scintillator is the key detector component in Double Chooz. Commissioning two types of scintillators in the innermost part of the detector is designed to achieve high detection efficiency, high energy resolution and signal reconstruction together with a powerful background rejection for neutrino observation. The scintillator installed in the very center is identified as Neutrino Target, which is Gadolinium-loaded, while a Gamma-Catcher scintillator without Gadolinium surrounds the Neutrino Target. To satisfy the above mentioned requirements, they are newly developed to assure the long term stability including the characteristics of high light yield, light transparency and adapted density.
In the poster, scintillator properties in their final large scale production and careful procedure for the filling of the Double Chooz detector will be presented.
