Abstract

Test modules of the ANTARES underwater neutrino detector have already been immersed several times with autonomous data acquisition and the construction of a string with electro-optical transmission of analog signals to the shore is in its final phase. The next generation prototypes are already under construction. Data are digitised inside the optical modules by a fast analog memory ASIC developed within the collaboration, the Analog Ring Sampler. Data waveforms and/or time and charges are stored locally until a local (level 1) or global (level 2) trigger is formed. Data rate reduction, data transmission along strings and to the shore and trigger designs with configurable analogue coincidences are described. Calibrations of time and amplitude are outlined
