The Double Chooz Hardware Trigger System — •Andi Cucoanes, Franz Beißel, Bernd Reinhold, Stefan Roth, Achim Stahl, and Christopher Wiebusch — RWTH Aachen
The Double Chooz neutrino experiment aims to improve the present knowledge on θ13 mixing angle using two similar detectors placed at ∼280 m and respectively 1 km from the Chooz power plant reactor cores. The detectors measure the disappearance of reactor antineutrinos.
The hardware trigger has to be very efficient for antineutrinos as well as for various types of background events. The triggering condition is based on discriminated PMT sum signals and the multiplicity of groups of PMTs.
The talk will give an outlook to the Double Chooz experiment and will explain the requirements of the trigger system. The resulting concept and its performance is shown as well as first results from a prototype system.
