Abstract :
This paper presents the hardware architecture and the main features of the ICARUS trigger system. The ICARUS detector is a very massive liquid Argon Time Projection Chamber aimed at the study of some of the fundamental issues of astroparticle physics such as solar and atmospheric neutrino interactions, neutrinos following a Supernova explosion, neutrino oscillations with beams from particle accelerators and nucleon decay as predicted by Grand Unification Theories. The main feature of the proposed trigger design is its "segmentation", i.e., the capability to trigger different sectors of the detector on different events allowing for the efficient detection of rare events
