Abstract

AbstractA single-channel data acquisition (DAQ) module is developed for the dark matter search experiment using a superheated emulsion detector. This paper describes the basic design of the instrument, containing analog signal conditioning and data acquisition using ARM-7-based System-On-Chip. This module detects the production of acoustic emission by superheated liquid due to bubble nucleation using a piezoelectric sensor. Testing of the DAQ module as a prototype of the actual experimental setup is also described with the results.
