英文摘要The darkside-50 experiment at the laboratori nazionali del gran sasso is a search for dark matter using a dual phase time projection chamber with 50 kg of low radioactivity argon as target. light signals from interactions in the argon are detected by a system of 38 photo-multiplier tubes (pmts), 19 above and 19 below the tpc volume inside the argon cryostat. we describe the electronics which processes the signals from the photo-multipliers, the trigger system which identifies events of interest, and the data-acquisition system which records the data for further analysis. the electronics include resistive voltage dividers on the pmts, custom pre-amplifiers mounted directly on the pmt voltage dividers in the liquid argon, and custom amplifier/discriminators (at room temperature). after amplification, the pmt signals are digitized in caen waveform digitizers, and caen logic modules are used to construct the trigger; the data acquisition system for the tpc is based on the fermilab artdaq software. the system has been in operation since early 2014.
