Abstract

BiDAQ is a custom filtering and data acquisition system designed for next-gen bolometric experiments dedicated to the search of neutrinoless double beta decay. The system is composed of 12-channel analog-to-digital boards interfaced with FPGA SoC modules that collect and transmit the 24-bit data to the storage computers with a sampling rate up to 25 kHz. Low noise, low power, high modularity and configurability, and an easy interface with Gigabit Ethernet are the main characteristics of the BiDAQ system.
