Description
The Double Chooz experiment, which will use the antineutrinos produced in the
Chooz nuclear power plant in France, aims at measuring theta_13 or further
lowering its limit if no signal is observed. To achieve this purpose, a new
concept using two detectors has been introduced: one close to the power plant
to monitor the flux of electron antineutrinos emitted by the power plant and
one at 1.05 km, where the disappearance is expected to be maximal. In addition,
the detector design has been optimized to reduce backgrounds. The expected
sensitivity at 90% C.L. is sin2(2theta_13)<0.03 (with Dm^2 =2.5 10^-3 eV^2) after three years of data taking.
The aim of this poster is to present the read-out chain and data acquisition
system of the Double Chooz experiment. All its components will be described
in detail from the photomultiplier tube to the storage of data on disk. Special
focus will be devoted to the capabilities of the 8 bits 500 MHz FADC waveform
digitisers and the Level-1 trigger and timing system. Data from the preliminary
performance of the ensemble will be shown. The on-line system will be also
discussed focusing on the high degree of diagnosis and real time data analysis
of the data monitoring system.
