Readout and Data Acquisition in the NEXT-NEW Detector based on SRS-ATCA

The Scalable Readout System (SRS) was defined by the CERN RD51 Collaboration as a multi-channel, scalable readout platform for a wide range of front ends. In 2014, SRS was ported to the ATCA (Advanced Telecommunications Computing Architecture) standard. NEXT is an underground experiment aimed at searching for neutrinoless double-beta decay. NEXT-DEMO, a small-scale demonstrator, was read-out using SRS. NEXT has adopted SRS-ATCA for its first stage, called NEXT-NEW. Our presentation will describe the readout, DAQ and trigger for NEXT-NEW based on SRS-ATCA. This is, to our knowledge, the first experiment operating entirely on SRS-ATCA.
