Front end electronics and trigger system for the KARMEN neutrino experiment

KARMEN is a 56-t liquid scintillation calorimeter for neutrino experiments using beam-dump neutrinos from the spallation neutron source ISIS of the Rutherford Appleton Laboratory. The central detector is surrounded by two layers of antidetectors to define the fiducial volume for v reactions. The architecture of the electronics system of the KARMEN detector is described. The readout of the position-sensitive calorimeter is controlled by a trigger processor that analyzes the sum energy and multiplicity of the 512 central detector modules. Zero suppression during the ADC (analog/digital converter) scan facilitates a fast readout. A sophisticated, high degree of multiplexing leads to an economical system.<
