The data acquisition architecture for the “dark matter experiment using Argon pulse-shaped discrimination” — DEAP-3600

This paper describes the Data Acquisition (DAQ) architecture for the DEAP-3600 experiment at SNOLAB in Ontario, Canada, which is searching for Weakly Interacting Massive Particles. (WIMPs). The identification of the WIMP is based on the rejection by signal discrimination of the beta decays from the liquid
³⁹
Ar composing the detector volume (3600kg). The Data Acquisition is based on commercial electronics modules for the waveform acquisition and custom electronics for the trigger decision system. The software layer (Midas) handles the overall experiment data taking process, and the monitoring of the experimental parameters.
